ALTER

This box indicates whether the selected users or groups hold the ALTER privilege, with the Grant option, on the selected table. To change the box's setting, click on the down arrow and select the setting that you want. You can select:

Yes

Grants the ALTER privilege without the Grant option (the right to grant the ALTER privilege on the selected table to other users and groups). If a user or group already has the ALTER privilege with the Grant option, Yes revokes the privilege and re-grants it without the option.

No

Revokes the ALTER privilege.

Grant

Grants the ALTER privilege with the Grant option. If a user or group already has ALTER without the Grant option, Grant provides the option.

The ALTER privilege on a table allows a user to:

• Add columns to the table

• Create or drop a primary key, a check constraint, or a trigger

• Create or drop a foreign key, provided that the user also has the REFERENCES privilege on the parent table

• Add or change a comment on a table

If you select multiple users or groups for whom you specified different settings (for example, Yes for one user andNo for the others), the ALTER box is blank. But the settings that you specified remain in effect.
