How do you set a cell to null in datagrip?

If set null is not an option, try synchronizing the table schema. Right click the table and Synchronize (Ctrl-Alt-Y)

You can either:

1. Select the field, right-click, and select "Set NULL"
2. Select the field, press CTRL+ALT+N (on Windows).

Note that boolean fields will show up as a box filled with a dash (-) when null.

If the "Set NULL" option is not appearing, you might need to refresh the schema which you can do by clicking the synchronize button:

or by pressing Ctrl+Alt+Y (on Windows).

In Windows, there are two easy ways:

1. Select specific field and then press Ctrl+Alt+N
2. Right click on the specific field and then select Set NULL

Also, be sure that your field is nullable otherwise, DataGrip WILL NOT present the Set NULL option :)
