-PURPOSE: Use this script to convert your OMOP V4 common data model to CDM V5.
-
-last revised: 04 August 2015
-authors:  Patrick Ryan, Chris Knoll, Anthony Sena
-
-!!!!!!!!!!!!!!!!!!!!! PLEASE READ THESE INSTRUCTIONS !!!!!!!!!!!!!!!!!!!!!!!!!!!
-
-This script was authored using OHDSI-SQL which will require you to run this
-script through SqlRender to creat a version that is compatible with your target
-RDBMS. We have pre-generated these scripts using SQL Render and have placed
-them in folders for each RDBMS. Depending on which script you are viewing, your
-instructions will be slightly different.
-
-General Assumptions
--------------------
-
-This script assumes that your V4 and V5 database are located on the same
-RDBMS server. It also assumes that the V4 and V5 databases were created
-using the standard data definition scripts for these databases. If you 
-altered your V4 database in any way, this script will likely require
-some mo
-
-Getting Started
----------------
-
-Before you can use this script, there are some prerequisites:
-
- 1. Create a target CDMv5 database on your database server using the 
-    appropriate script from https://github.com/OHDSI/CommonDataModel
- 2. Load VocabV5 into the target database/schema that will contain CDMv5 using
-    Athena: http://ohdsi.org/web/ATHENA
-
-OHDSI-SQL File Instructions
------------------------------
- 
- 1. Set parameter name of schema that contains CDMv4 instance 
-    (@SOURCE_CDMV4, @SOURCE_CDMV4_SCHEMA)
- 2. Set parameter name of schema that contains CDMv5 instance 
-    (@TARGET_CDMV5, @TARGET_CDMV5_SCHEMA)
- 3. Run this script through SqlRender to produce a script that will work in your
-    source dialect. SqlRender can be found here: https://github.com/OHDSI/SqlRender
- 4. Run the script produced by SQL Render on your target RDBDMS.
-
-<RDBMS> File Instructions
--------------------------
-
- 1. This script will hold a number of placeholders for your CDM V4 and CDMV5
-    database/schema. In order to make this file work in your environment, you 
-	should plan to do a global "FIND AND REPLACE" on this file to fill in the 
-	file with values that pertain to your environment. The following are the 
-	tokens you should use when doing your "FIND AND REPLACE" operation:
-
-	a. [SOURCE_CDMV4]
-	b. [SOURCE_CDMV4].[SCHEMA]
-    c. [TARGET_CDMV5]
-	d. [TARGET_CDMV5].[SCHEMA]
-
- 2. Run the resulting script on your target RDBDMS.
-

- * The #concept_map table will hold the mapping of source_concept_ids to target_concept_ids
- * and their respective domain_ids. As a result, the results of this table will have 
- * some source_concept_ids that map to multiple target_concept_ids which is expected.
- *
- * In some of the conversion queries below, we will use the distinct values from the
- * #concept_map table since our need in those instances is to understand the domain_id
- * that will provide the destination table in the target V5 database. To make the code
- * easier to read, we dervied a #concept_map_distinct table that holds the distinct
- * source_concept_id and target domain_id.
- *
- * As of the dateof this script, the following domains contain source_concept_ids that 
- * map to multiple target_concept_ids:
- *
- * Condition
- * Device
- * Drug
- * Measurement
- * Observation
- * Procedure
- * Spec Anatomic Site
- *
- * Also, as of the date which this script was authored, no source_concept_ids map to multiple domains

-PURPOSE: Use this script to convert your OMOP V4 common data model to CDM V5.
-
-last revised: 04 August 2015
-authors:  Patrick Ryan, Chris Knoll, Anthony Sena
-
-!!!!!!!!!!!!!!!!!!!!! PLEASE READ THESE INSTRUCTIONS !!!!!!!!!!!!!!!!!!!!!!!!!!!
-
-This script was authored using OHDSI-SQL which will require you to run this
-script through SqlRender to creat a version that is compatible with your target
-RDBMS. We have pre-generated these scripts using SQL Render and have placed
-them in folders for each RDBMS. Depending on which script you are viewing, your
-instructions will be slightly different.
-
-General Assumptions
--------------------
-
-This script assumes that your V4 and V5 database are located on the same
-RDBMS server. It also assumes that the V4 and V5 databases were created
-using the standard data definition scripts for these databases. If you 
-altered your V4 database in any way, this script will likely require
-some mo
-
-Getting Started
----------------
-
-Before you can use this script, there are some prerequisites:
-
- 1. Create a target CDMv5 database on your database server using the 
-    appropriate script from https://github.com/OHDSI/CommonDataModel
- 2. Load VocabV5 into the target database/schema that will contain CDMv5 using
-    Athena: http://ohdsi.org/web/ATHENA
-
-OHDSI-SQL File Instructions
------------------------------
- 
- 1. Set parameter name of schema that contains CDMv4 instance 
-    ([SOURCE_CDMV4], [SOURCE_CDMV4].[SCHEMA])
- 2. Set parameter name of schema that contains CDMv5 instance 
-    ([TARGET_CDMV5], [TARGET_CDMV5].[SCHEMA])
- 3. Run this script through SqlRender to produce a script that will work in your
-    source dialect. SqlRender can be found here: https://github.com/OHDSI/SqlRender
- 4. Run the script produced by SQL Render on your target RDBDMS.
-
-<RDBMS> File Instructions
--------------------------
-
- 1. This script will hold a number of placeholders for your CDM V4 and CDMV5
-    database/schema. In order to make this file work in your environment, you 
-	should plan to do a global "FIND AND REPLACE" on this file to fill in the 
-	file with values that pertain to your environment. The following are the 
-	tokens you should use when doing your "FIND AND REPLACE" operation:
-
-	a. [SOURCE_CDMV4]
-	b. [SOURCE_CDMV4].[SCHEMA]
-    c. [TARGET_CDMV5]
-	d. [TARGET_CDMV5].[SCHEMA]
-
- 2. Run the resulting script on your target RDBDMS.
-
-*********************************************************************************/
-/* SCRIPT PARAMETERS */
- -- The CDMv4 database name
-	 -- The CDMv4 database plus schema
-	 -- The target CDMv5 database name
-	 -- the target CDMv5 database plus schema
-
-ALTER SESSION SET current_schema =  [TARGET_CDMV5];
-
-/*
- * The #concept_map table will hold the mapping of source_concept_ids to target_concept_ids
- * and their respective domain_ids. As a result, the results of this table will have 
- * some source_concept_ids that map to multiple target_concept_ids which is expected.
- *
- * In some of the conversion queries below, we will use the distinct values from the
- * #concept_map table since our need in those instances is to understand the domain_id
- * that will provide the destination table in the target V5 database. To make the code
- * easier to read, we dervied a #concept_map_distinct table that holds the distinct
- * source_concept_id and target domain_id.
- *
- * As of the dateof this script, the following domains contain source_concept_ids that 
- * map to multiple target_concept_ids:
- *
- * Condition
- * Device
- * Drug
- * Measurement
- * Observation
- * Procedure
- * Spec Anatomic Site
- *
- * Also, as of the date which this script was authored, no source_concept_ids map to multiple domains

-PURPOSE: Use this script to convert your OMOP V4 common data model to CDM V5.
-
-last revised: 04 August 2015
-authors:  Patrick Ryan, Chris Knoll, Anthony Sena
-
-!!!!!!!!!!!!!!!!!!!!! PLEASE READ THESE INSTRUCTIONS !!!!!!!!!!!!!!!!!!!!!!!!!!!
-
-This script was authored using OHDSI-SQL which will require you to run this
-script through SqlRender to creat a version that is compatible with your target
-RDBMS. We have pre-generated these scripts using SQL Render and have placed
-them in folders for each RDBMS. Depending on which script you are viewing, your
-instructions will be slightly different.
-
-General Assumptions
--------------------
-
-This script assumes that your V4 and V5 database are located on the same
-RDBMS server. It also assumes that the V4 and V5 databases were created
-using the standard data definition scripts for these databases. If you 
-altered your V4 database in any way, this script will likely require
-some mo
-
-Getting Started
----------------
-
-Before you can use this script, there are some prerequisites:
-
- 1. Create a target CDMv5 database on your database server using the 
-    appropriate script from https://github.com/OHDSI/CommonDataModel
- 2. Load VocabV5 into the target database/schema that will contain CDMv5 using
-    Athena: http://ohdsi.org/web/ATHENA
-
-OHDSI-SQL File Instructions
------------------------------
- 
- 1. Set parameter name of schema that contains CDMv4 instance 
-    ([SOURCE_CDMV4], [SOURCE_CDMV4].[SCHEMA])
- 2. Set parameter name of schema that contains CDMv5 instance 
-    ([TARGET_CDMV5], [TARGET_CDMV5].[SCHEMA])
- 3. Run this script through SqlRender to produce a script that will work in your
-    source dialect. SqlRender can be found here: https://github.com/OHDSI/SqlRender
- 4. Run the script produced by SQL Render on your target RDBDMS.
-
-<RDBMS> File Instructions
--------------------------
-
- 1. This script will hold a number of placeholders for your CDM V4 and CDMV5
-    database/schema. In order to make this file work in your environment, you 
-	should plan to do a global "FIND AND REPLACE" on this file to fill in the 
-	file with values that pertain to your environment. The following are the 
-	tokens you should use when doing your "FIND AND REPLACE" operation:
-
-	a. [SOURCE_CDMV4]
-	b. [SOURCE_CDMV4].[SCHEMA]
-    c. [TARGET_CDMV5]
-	d. [TARGET_CDMV5].[SCHEMA]
-
- 2. Run the resulting script on your target RDBDMS.
-
-*********************************************************************************/
-/* SCRIPT PARAMETERS */
- -- The CDMv4 database name
-	 -- The CDMv4 database plus schema
-	 -- The target CDMv5 database name
-	 -- the target CDMv5 database plus schema
-
-SET search_path TO  [TARGET_CDMV5];
-
-/*
- * The #concept_map table will hold the mapping of source_concept_ids to target_concept_ids
- * and their respective domain_ids. As a result, the results of this table will have 
- * some source_concept_ids that map to multiple target_concept_ids which is expected.
- *
- * In some of the conversion queries below, we will use the distinct values from the
- * #concept_map table since our need in those instances is to understand the domain_id
- * that will provide the destination table in the target V5 database. To make the code
- * easier to read, we dervied a #concept_map_distinct table that holds the distinct
- * source_concept_id and target domain_id.
- *
- * As of the dateof this script, the following domains contain source_concept_ids that 
- * map to multiple target_concept_ids:
- *
- * Condition
- * Device
- * Drug
- * Measurement
- * Observation
- * Procedure
- * Spec Anatomic Site
- *
- * Also, as of the date which this script was authored, no source_concept_ids map to multiple domains

-Conversion from CDM v4 to CDM v5
-==============================================================
-
-The scripts in this directory will aid you in moving your data from the Common Data Model (CDM) version 4 to version 5. 
-
-Overview
-==============================================================
-
-The resources in this folder provide you with a means for converting your CDM V4 database to CDM V5. The goal of these scripts is to provide a path for converting your data to the CDM V5 to take advantage of the other tools that are being built to support research on CDM V5. These scripts are **NOT** designed to replace a proper ETL from your source data to CDM V5.
-
-One of the most important aspects to this conversion script is the use of the **[Standarized Vocabularies](http://www.ohdsi.org/web/wiki/doku.php?id=documentation:vocabulary:introduction "Standarized Vocabularies")** to map from tables in the V4 database to their cooresponding V5 table using the vocabulary **[domains](http://www.ohdsi.org/web/wiki/doku.php?id=documentation:vocabulary:domains "domains")**. At the beginning of the conversion script, we create a #concept\_map temporary table which holds a mapping from source_concept_id's to standard target_concept_ids for each of the domains. This table is then used throughout the remainder of the script to map rows from each of the source V4 tables (i.e. condition\_occurrence) to the proper table in the V5 data model. As a result, the number of rows in the V4 condition\_occurrence will not be the same as in V5 since some rows may be converted to a different table based on the standard concept mapping. 
-
-Assumptions
-==============================================================
-
-We have created a directory per Relational Database Management System (RDBMS) that contains the conversion script for that database platform. All of the scripts have the same assumptions:
-
-1. Your source CDM V4 database is on the same sever as your target CDM v5 database.
-2. You have read rights to the CDM V4 database and database owner privileges on the target V5 database as this script will create an "ETL_WARNINGS" table in the process.
-3. You have enough storage on your database server to perform the conversion. 
-
-Usage
-=====
-
-1. **Create your V5 Target Database:** Create a CDM V5 database on the same server as your CDM V4 database by using the **[Common Data Model Scripts](https://github.com/OHDSI/CommonDataModel "Common Data Model Scripts")** for your RDBMS. **NOTE: Please review the data types that exist on your V4 database and ensure you carry forward any data type changes from V4 to V5. For example, if you converted columns from an INT to a BIGINT to accommodate tables with > 2.1 Billion Rows, you will need to make the corresponding changes in your V5 Database and potentially to this conversion script** 
- 
-2. **Load the V5 Vocabulary**: Download the V5 vocabulary from **[Athena](http://www.ohdsi.org/web/athena/ "Athena")** and load them into the V5 database created in step 1 above.
-
-2. **Download the conversion script:** The **[CDM V4 to V5 Conversion](https://github.com/OHDSI/CommonDataModel/tree/master/Version4%20To%20Version5%20Conversion "CDM V4 to V5 Conversion Directory")** folder has subfolders with scripts that will work on each RDBMS.  In order to make this file work in your environment, you will need to perform a global "FIND AND REPLACE" on the conversion script to fill in the file with values that pertain to your environment. The following are the tokens you should use when doing your "FIND AND REPLACE" operation:
- 
-	 * [SOURCE_CDMV4] - Your V4 database name
-	 * [SOURCE_CDMV4].[SCHEMA] - Your V4 database name + schema
-     * [TARGET_CDMV5] - Your V5 database name
-	 * [TARGET_CDMV5].[SCHEMA] - Your V5 database name + schema
-
-3. Run the resulting script on your target RDBDMS. ** **NOTE** ** If you are running the Oracle script via Sql Developer or similar, you may need to alter the script to include the appropriate "/" symbols to mark the end of the anonymous code blocks. This has been done in the Oracle script that has been provided in this repository.
-4. At the end of the conversion process, several tables will be produced that will help you to understand how your data has changed as a result of the conversion process. This is described in the Quality Assurance section below.
-
-
-Quality Assurance
-===================
-
-At the end of the conversion script, there are 3 queries which will provide information on the conversion process. For reference, this section of the conversion script has a header comment:
-
-/**** QUALITY ASSURANCE OUTPUT ****/
-
-The first query provides a means for comparing the table row counts between the V4 and V5 databases.  As mentioned in the overview section above, table row counts will differ between V4 and V5 based on the way that the standard vocabulary maps the data. The next set of queries will help to tie out the row count changes in these tables. 
-
-The second query shows the source V4 table (i.e condition\_occurrence) and how the row counts maps to the V5 domain. This table is useful to understand how the data from the V4 source was distributed into the V5 tables. As a note, 1 record in the V4 table could map to multiple records in V5 as some concepts will map to multiple standard domains.
-
-The third query uses the information from the second query and provides a summary for each V5 domain. This is useful for tying out the rowcounts we'd expect from the script with the actual results observed in the first query. 
-
-We have included a spreadsheet called "QA-Results.xlsx" which provides an example of how to utilize these 3 result queries to understand the results of the conversion process. The results of the first query go into the "Rowcounts" worksheet. The results of the second and third queries go into the "Classification Map Results" worksheet. If the conversion process worked as expected, all of the "Difference" columns should equal 0 in the "Classification Map Results" worksheet.
-
-Getting Involved
-==============================================================
-Each script found in the RDBMS directory was generated from the OHDSI-SQL file: *OMOP CDMv4 to CDMv5 - OHDSI-SQL.sql* found in the root of this directory. If you would like to contribute to this script, we'd suggest you modify this script and use **[SqlRender](https://github.com/OHDSI/SqlRender "SqlRender")** to re-generate the specific RDBMS scripts. We have also supplied a basic R script in this directory to help re-generate the scripts using SqlRender.

-PURPOSE: Use this script to convert your OMOP V4 common data model to CDM V5.
-
-last revised: 04 August 2015
-authors:  Patrick Ryan, Chris Knoll, Anthony Sena
-
-!!!!!!!!!!!!!!!!!!!!! PLEASE READ THESE INSTRUCTIONS !!!!!!!!!!!!!!!!!!!!!!!!!!!
-
-This script was authored using OHDSI-SQL which will require you to run this
-script through SqlRender to creat a version that is compatible with your target
-RDBMS. We have pre-generated these scripts using SQL Render and have placed
-them in folders for each RDBMS. Depending on which script you are viewing, your
-instructions will be slightly different.
-
-General Assumptions
--------------------
-
-This script assumes that your V4 and V5 database are located on the same
-RDBMS server. It also assumes that the V4 and V5 databases were created
-using the standard data definition scripts for these databases. If you 
-altered your V4 database in any way, this script will likely require
-some mo
-
-Getting Started
----------------
-
-Before you can use this script, there are some prerequisites:
-
- 1. Create a target CDMv5 database on your database server using the 
-    appropriate script from https://github.com/OHDSI/CommonDataModel
- 2. Load VocabV5 into the target database/schema that will contain CDMv5 using
-    Athena: http://ohdsi.org/web/ATHENA
-
-OHDSI-SQL File Instructions
------------------------------
- 
- 1. Set parameter name of schema that contains CDMv4 instance 
-    ([SOURCE_CDMV4], [SOURCE_CDMV4].[SCHEMA])
- 2. Set parameter name of schema that contains CDMv5 instance 
-    ([TARGET_CDMV5], [TARGET_CDMV5].[SCHEMA])
- 3. Run this script through SqlRender to produce a script that will work in your
-    source dialect. SqlRender can be found here: https://github.com/OHDSI/SqlRender
- 4. Run the script produced by SQL Render on your target RDBDMS.
-
-<RDBMS> File Instructions
--------------------------
-
- 1. This script will hold a number of placeholders for your CDM V4 and CDMV5
-    database/schema. In order to make this file work in your environment, you 
-	should plan to do a global "FIND AND REPLACE" on this file to fill in the 
-	file with values that pertain to your environment. The following are the 
-	tokens you should use when doing your "FIND AND REPLACE" operation:
-
-	a. [SOURCE_CDMV4]
-	b. [SOURCE_CDMV4].[SCHEMA]
-    c. [TARGET_CDMV5]
-	d. [TARGET_CDMV5].[SCHEMA]
-
- 2. Run the resulting script on your target RDBDMS.
-

-/* SCRIPT PARAMETERS */
- -- The CDMv4 database name
-	 -- The CDMv4 database plus schema
-	 -- The target CDMv5 database name

- * The #concept_map table will hold the mapping of source_concept_ids to target_concept_ids
- * and their respective domain_ids. As a result, the results of this table will have 
- * some source_concept_ids that map to multiple target_concept_ids which is expected.
- *
- * In some of the conversion queries below, we will use the distinct values from the

- * easier to read, we dervied a #concept_map_distinct table that holds the distinct
- * source_concept_id and target domain_id.

- *
- * Condition
- * Device
- * Drug
- * Measurement
- * Observation
- * Procedure
- * Spec Anatomic Site

-PURPOSE: Use this script to convert your OMOP V4 common data model to CDM V5.
-
-last revised: 04 August 2015
-authors:  Patrick Ryan, Chris Knoll, Anthony Sena
-
-!!!!!!!!!!!!!!!!!!!!! PLEASE READ THESE INSTRUCTIONS !!!!!!!!!!!!!!!!!!!!!!!!!!!
-
-This script was authored using OHDSI-SQL which will require you to run this
-script through SqlRender to creat a version that is compatible with your target
-RDBMS. We have pre-generated these scripts using SQL Render and have placed
-them in folders for each RDBMS. Depending on which script you are viewing, your
-instructions will be slightly different.
-
-General Assumptions
--------------------
-
-This script assumes that your V4 and V5 database are located on the same
-RDBMS server. It also assumes that the V4 and V5 databases were created
-using the standard data definition scripts for these databases. If you 
-altered your V4 database in any way, this script will likely require
-some mo
-
-Getting Started
----------------
-
-Before you can use this script, there are some prerequisites:
-
- 1. Create a target CDMv5 database on your database server using the 
-    appropriate script from https://github.com/OHDSI/CommonDataModel
- 2. Load VocabV5 into the target database/schema that will contain CDMv5 using
-    Athena: http://ohdsi.org/web/ATHENA
-
-OHDSI-SQL File Instructions
------------------------------
- 
- 1. Set parameter name of schema that contains CDMv4 instance 
-    ([SOURCE_CDMV4], [SOURCE_CDMV4].[SCHEMA])
- 2. Set parameter name of schema that contains CDMv5 instance 
-    ([TARGET_CDMV5], [TARGET_CDMV5].[SCHEMA])
- 3. Run this script through SqlRender to produce a script that will work in your
-    source dialect. SqlRender can be found here: https://github.com/OHDSI/SqlRender
- 4. Run the script produced by SQL Render on your target RDBDMS.
-
-<RDBMS> File Instructions
--------------------------
-
- 1. This script will hold a number of placeholders for your CDM V4 and CDMV5
-    database/schema. In order to make this file work in your environment, you 
-	should plan to do a global "FIND AND REPLACE" on this file to fill in the 
-	file with values that pertain to your environment. The following are the 
-	tokens you should use when doing your "FIND AND REPLACE" operation:
-
-	a. [SOURCE_CDMV4]
-	b. [SOURCE_CDMV4].[SCHEMA]
-    c. [TARGET_CDMV5]
-	d. [TARGET_CDMV5].[SCHEMA]
-
- 2. Run the resulting script on your target RDBDMS.
-
-*********************************************************************************/
-/* SCRIPT PARAMETERS */
- -- The CDMv4 database name
-	 -- The CDMv4 database plus schema
-	 -- The target CDMv5 database name
-	 -- the target CDMv5 database plus schema
-
-USE [TARGET_CDMV5];
-
-/*
- * The #concept_map table will hold the mapping of source_concept_ids to target_concept_ids
- * and their respective domain_ids. As a result, the results of this table will have 
- * some source_concept_ids that map to multiple target_concept_ids which is expected.
- *
- * In some of the conversion queries below, we will use the distinct values from the
- * #concept_map table since our need in those instances is to understand the domain_id
- * that will provide the destination table in the target V5 database. To make the code
- * easier to read, we dervied a #concept_map_distinct table that holds the distinct
- * source_concept_id and target domain_id.
- *
- * As of the dateof this script, the following domains contain source_concept_ids that 
- * map to multiple target_concept_ids:
- *
- * Condition
- * Device
- * Drug
- * Measurement
- * Observation
- * Procedure
- * Spec Anatomic Site
- *
- * Also, as of the date which this script was authored, no source_concept_ids map to multiple domains

-PURPOSE: Use this script to convert your OMOP V4 common data model to CDM V5.
-
-last revised: 04 August 2015
-authors:  Patrick Ryan, Chris Knoll, Anthony Sena
-
-!!!!!!!!!!!!!!!!!!!!! PLEASE READ THESE INSTRUCTIONS !!!!!!!!!!!!!!!!!!!!!!!!!!!
-
-This script was authored using OHDSI-SQL which will require you to run this
-script through SqlRender to creat a version that is compatible with your target
-RDBMS. We have pre-generated these scripts using SQL Render and have placed
-them in folders for each RDBMS. Depending on which script you are viewing, your
-instructions will be slightly different.
-
-General Assumptions
--------------------
-
-This script assumes that your V4 and V5 database are located on the same
-RDBMS server. It also assumes that the V4 and V5 databases were created
-using the standard data definition scripts for these databases. If you 
-altered your V4 database in any way, this script will likely require
-some mo
-
-Getting Started
----------------
-
-Before you can use this script, there are some prerequisites:
-
- 1. Create a target CDMv5 database on your database server using the 
-    appropriate script from https://github.com/OHDSI/CommonDataModel
- 2. Load VocabV5 into the target database/schema that will contain CDMv5 using
-    Athena: http://ohdsi.org/web/ATHENA
-
-OHDSI-SQL File Instructions
------------------------------
- 
- 1. Set parameter name of schema that contains CDMv4 instance 
-    ([SOURCE_CDMV4], [SOURCE_CDMV4].[SCHEMA])
- 2. Set parameter name of schema that contains CDMv5 instance 
-    ([TARGET_CDMV5], [TARGET_CDMV5].[SCHEMA])
- 3. Run this script through SqlRender to produce a script that will work in your
-    source dialect. SqlRender can be found here: https://github.com/OHDSI/SqlRender
- 4. Run the script produced by SQL Render on your target RDBDMS.
-
-<RDBMS> File Instructions
--------------------------
-
- 1. This script will hold a number of placeholders for your CDM V4 and CDMV5
-    database/schema. In order to make this file work in your environment, you 
-	should plan to do a global "FIND AND REPLACE" on this file to fill in the 
-	file with values that pertain to your environment. The following are the 
-	tokens you should use when doing your "FIND AND REPLACE" operation:
-
-	a. [SOURCE_CDMV4]
-	b. [SOURCE_CDMV4].[SCHEMA]
-    c. [TARGET_CDMV5]
-	d. [TARGET_CDMV5].[SCHEMA]
-
- 2. Run the resulting script on your target RDBDMS.
-
-*********************************************************************************/
-/* SCRIPT PARAMETERS */
- -- The CDMv4 database name
-	 -- The CDMv4 database plus schema
-	 -- The target CDMv5 database name
-	 -- the target CDMv5 database plus schema
-
-USE [TARGET_CDMV5];
-
-/*
- * The #concept_map table will hold the mapping of source_concept_ids to target_concept_ids
- * and their respective domain_ids. As a result, the results of this table will have 
- * some source_concept_ids that map to multiple target_concept_ids which is expected.
- *
- * In some of the conversion queries below, we will use the distinct values from the
- * #concept_map table since our need in those instances is to understand the domain_id
- * that will provide the destination table in the target V5 database. To make the code
- * easier to read, we dervied a #concept_map_distinct table that holds the distinct
- * source_concept_id and target domain_id.
- *
- * As of the dateof this script, the following domains contain source_concept_ids that 
- * map to multiple target_concept_ids:
- *
- * Condition
- * Device
- * Drug
- * Measurement
- * Observation
- * Procedure
- * Spec Anatomic Site
- *
- * Also, as of the date which this script was authored, no source_concept_ids map to multiple domains

-Common-Data-Model / Oracle
-=================
-
-This folder contains the SQL scripts for Oracle. 
-
-In order to create your instantiation of the Common Data Model, we recommend following these steps:
-
-1. Create an empty schema.
-
-2. Execute the script `CDM V4 ddl.sql` to create the tables and fields.
-
-3. Load your data into the schema using the loading scripts in VocabImport
-
-Note: you could also apply the constraints and the indexes after loading the data, this will speed up the insertion of the data considerably.

-script to load the Vocabulary related tables in the OMOP common data model, version 4.5 for Oracle database
-
-last revised: 19 Mar 2015
-
-author:  Lee Evans
-
-Notes
-
-1) This script assumes the CDM version 4.5 vocabulary zip file has been unzipped into the "C:\CDM" directory. 
-2) If you unzipped your CDM version 4.5 vocabulary files into a different directory then replace all file paths below, with your directory path.
-3) If you have existing data in your CDM vocabulary tables then backup that data (if needed) and truncate those tables before loading

-1) This script assumes the CDM version 4.5 vocabulary zip file has been unzipped into the "C:\CDM" directory. 
-2) If you unzipped your CDM version 4.5 vocabulary files into a different directory then replace all file paths below, with your directory path.
-3) Run this SQL query script in the database where you created your CDM Version 4.5 tables
