Description
Hello OHDSI team,
I am working with a large OMOP CDM instance hosted on SAP HANA (HANA 2.x).
Currently, the OHDSI toolchain—specifically SqlRender + DatabaseConnector + DataQualityDashboard—does not support HANA as a database dialect.
I am opening this issue to request official support for SAP HANA as an additional DBMS option in the OHDSI ecosystem.
Right now, Data quality dashboard cannot run on HANA because:
-
DatabaseConnector::connect() enforces a whitelist of DBMS names (no "hana" option).
-
SqlRender has no "hana" translation dialect.
-
DQD relies on SqlRender and therefore cannot translate SQL to HANA syntax.
Thank you,
Simon

Research direction
Start with DatabaseConnector::connect() and the SqlRender dialect handling described in the issue, then trace how DataQualityDashboard uses them. Determine the existing DBMS support boundaries and the requirements for adding SAP HANA translation. Done means DatabaseConnector accepts HANA and the dependent toolchain can generate and run compatible SQL.
