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
([CDM], [CDM].[CDMSCHEMA])
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:
[CMD]
[CDM].[CDMSCHEMA]
