Code Inspection: Statement with side effects

Reports statements that might lead to modification of a database during a read-only connection.

To enable read-only mode for a connection, right-click a data source in the Database tool window (View | Tool Windows | Database) and select Properties. In the Data Sources and Drivers dialog, click the Options tab and select the Read-only checkbox.

Example (MySQL):

CREATE TABLE foo(a INT); INSERT INTO foo VALUES (1);


As CREATE TABLE and INSERT INTO statements lead to a database modification, these statements will be highlighted in read-only connection mode.

Suppress an inspection in the editor

  1. Position the caret at the highlighted line and press Alt+Enter or click the Intention action icon.

  2. Click the arrow next to the inspection you want to suppress and select the necessary suppress action.
