A popular subclause of DDL statements that jOOQ can usually emulate, is the IF EXISTS clause:
Dialect support
This example using jOOQ:
alterViewIfExists("v").renameTo("new_name")
Translates to the following dialect specific expressions:
-- AURORA_POSTGRES, COCKROACHDB, DUCKDB, H2, POSTGRES
ALTER VIEW IF EXISTS v RENAME TO new_name
-- ORACLE
BEGIN
EXECUTE IMMEDIATE '
RENAME v TO new_name
';
EXCEPTION
WHEN others THEN
IF sqlerrm LIKE 'ORA-00942%' THEN NULL;
ELSIF sqlerrm LIKE 'ORA-04043%' THEN NULL;
ELSE RAISE;
END IF;
END;
-- SNOWFLAKE
ALTER VIEW v RENAME TO new_name
-- SQLSERVER
BEGIN TRY
EXEC sp_rename v, new_name
END TRY
BEGIN CATCH
IF error_number() != 15225 THROW;
END CATCH
