SqlRender 1.19.1

Bugfixes:

  1. Some additional translation rules for InterSystems IRIS.

SqlRender 1.19.02024-10-09

Changes:

  1. When creating emulated temp tables (Oracle, Spark, BigQuery), will first attempt to drop (if exist). This is to clean up any orphan tables from a previous (unsuccesful) run.

  2. Adding tentative support for InterSystems IRIS. Could still be removed.

Bugfixes:

  1. On Snowflake, fixed ‘This session does not have a current schema’ error when translating legacy IF OBJECT_ID('tempdb..#table', 'U') IS NOT NULL DROP TABLE #table;

SqlRender 1.18.12024-08-21

Changes:

  1. Changing Spark translation of DATEADD() from DATE_ADD() to DATEADD() as required by some but not all Databricks instances.

Bugfixes:

  1. Fixed DuckDb translation of CAST(CONCATENATE(...) AS DATE).

  2. Fix Snowflake and DataBricks translation of CAST(... AS DATE) when ... is a literal.

SqlRender 1.18.02024-05-30

Changes:

  1. Adding translation for bitwise AND operator (&).

The new limit comes from PostgreSQL, which by default allows for 63 characters. All other supported DBMSs allow for longer names.

Bugfixes:

  1. For SQLite, now translating ALTER TABLE ALTER COLUMN BIGINTto dummy statement (SELECT 0;), since all integer types are the same on SQLite.

  2. Fixed translation of ALTER TABLE ALTER COLUMN on PostgreSQL.

  3. More robust detection of string concatenation for BigQuery.

SqlRender 1.17.02024-03-20

Changes:

SqlRender 1.16.12023-10-07

Changes:

  1. Adding support for ALTER TABLE ADD COLUMN for PostgreSQL, even though it is not correct OhdsiSql (because it is not valid SQL Server SQL).
