The OHDSI tools only support the following database platforms:
- Microsoft SQL Server
- Microsoft Parallel Data Warehouse (a.k.a. Analytics Platform System)
- Amazon Redshift
- Apache Impala
- Google BigQuery
- IBM Netezza
We looked at MySQL in the past, but found that it had too many restrictions (e.g. a temp table could only be referenced once in a query). We do not expect to add support for MySQL. I recommend you use another platform like PostgreSQL.
