OR REPLACE

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

Many dialects support a convenient OR REPLACE clause that allows for dropping any pre-existing view by the same name in a single statement.

// Create a new view
create.createOrReplaceView("early_authors", "author_id", "first_name", "last_name")
      .as(select(AUTHOR.ID, AUTHOR.FIRST_NAME, AUTHOR.LAST_NAME)
          .from(AUTHOR)

          // Any inserted or updated authors must continue to satisfy this condition
          .where(AUTHOR.ID.lt(200)))
      .execute();
