DataGrip 2019.3 Help

Refactoring code

Refactoring is a process of improving your source code without creating a new functionality. Refactoring helps you keep your code solid and easy to maintain.

Rename refactoring

Rename database objects

  1. Place the caret at the object that you want to rename.

  2. Navigate to Refactor | Rename Shift+F6. If you edit an argument in the function, you can start typing a new name inline, or press Shift+F6 twice to invoke the Rename dialog.

  3. In the Rename dialog, type a new name for the object.

  4. Review changes and click Refactor. To search for usages of the object name, click Preview.

Extract refactorings

Extract a variable

  1. Place the caret on a variable in the function.

  2. Navigate to Refactor | Extract | Variable (Ctrl+Alt+V).

  3. Select a part of the expression that you want to extract and press Enter.

Extract as a Common Table Expression (CTE)

CTE is a temporary result set that you can use within another SELECT, INSERT, UPDATE, or DELETE statements. In DataGrip you can extract a subquery and convert it to CTE.

  1. Place the caret inside the subquery that you want to convert.

  2. Navigate to Refactor | Extract | Subquery as CTE.

Preview refactoring changes

For some refactorings, DataGrip lets you preview changes before applying them.

  1. To see potential changes (the list of usages where the refactoring will be performed), click Preview in the Refactoring Preview dialog.

  2. Check the changes that are going to be made in the Find tool window. You can exclude Delete or remove Ctrl+X changes that you consider unnecessary.

  3. Click Do Refactor to proceed with the changes.
