Description
ALTER GROUP is used to add or remove users from a
group. Only database superusers can use this command.
Adding a user to a group does not create the user. Similarly, removing
a user from a group does not drop the user itself.
Use CREATE GROUP
to create a new group and DROP GROUP to remove a group.
Usage
Add users to a group:
ALTER GROUP staff ADD USER karl, john
Remove a user from a group:
ALTER GROUP workers DROP USER beth
Compatibility
SQL92
There is no ALTER GROUP statement in
SQL92. The concept of roles is
similar.
