ALTER SCHEMA IF EXISTS

Applies to ✅ Open Source Edition   ✅ Express Edition   ✅ Professional Edition   ✅ Enterprise Edition

A popular subclause of DDL statements that jOOQ can usually emulate, is the IF EXISTS clause:

// Renaming the schema
create.alterSchemaIfExists("old_schema").renameTo("new_schema").execute();

Dialect support

This example using jOOQ:

alterSchemaIfExists("s").renameTo("t")

Translates to the following dialect specific expressions:

H2, Snowflake

ALTER SCHEMA IF EXISTS s RENAME TO t

Hana

DO BEGIN
  DECLARE EXIT HANDLER FOR SQL_ERROR_CODE 362 BEGIN END;
  EXECUTE IMMEDIATE '
    RENAME SCHEMA s TO t
  ';
END;
