ALTER

This box indicates whether the selected use holds the ALTER privilege, with the Grant option, on the on the table or tables selected in the Table column. 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 to groups). If the user 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 the user 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 tables for which you specified different settings (for example, Yes for one table andNo for the others), the ALTER box is blank. But the settings that you specified remain in effect.
