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.
