After you reviewed changes in the object source code, you can submit these changes to a database. When you press the Submit button () in the Database changes tool window, you see the Object Migration dialog. The Object Migration dialog displays a migration script for the object.
A migration script is code that changes all database or a part of it. You can use migration scripts to add or remove a column, upgrade the database version, or change column properties.
IntelliJ IDEA can automatically generate a migration script but you must check it before running.
You can use a migration tool for the following types of SQL objects: procedures, functions, views, materialized views, rules (PostgreSQL), events (MySQL), scripts (Exasol), triggers (except for PostgreSQL).
Generate a migration script
Select two schemas, right-click any of them, and click Compare. Alternatively, select two schemas and press Ctrl+D.
In the Diff Between <schema_1> and <schema_2> dialog, specify comparing options.
Depending on the migration direction, click Migrate Left or Migrate right.
Modify SQL objects with a migration tool
Double-click the database object.
Make changes in a source code of the object. IntelliJ IDEA highlights all changes in the gutter.
Click the Submit icon ().
In the Object Migration window, review changes and click OK.
