ALTER GROUP
Valid in: SQL, ESQL, OpenAPI, ODBC, JDBC, .NET
The ALTER GROUP statement modifies the list of users associated with a group identifier. Individual users can be added or dropped or the entire list can be dropped.
An add and a drop operation cannot be performed in the same ALTER GROUP statement.
This statement has the following format:
[EXEC SQL] ALTER GROUP group_id {, group_id}
ADD USERS (user_id {, user_id}) | DROP USERS (user_id {, user_id}) | DROP ALL
ALTER GROUP group_id {, group_id}
Modifies the list of users associated with a group identifier (group_id).
The group_id must be an existing group identifier. If a non-existent group_id is specified, a warning is issued and processing continues with the next valid group_id in the list.
ADD USERS (user_id {, user_id})
Adds the specified user_ids to the specified the group_ids.
The user_ids must exist to be added to a group. If a specified user_id does not exist, an error is issued and processing continues with the remaining user_ids.
If a specific user_id occurs more than once in the user list, additional occurrences of the specified user_id are ignored. No errors are issued.
DROP USERS (user_id {, user_id})
Removes the specified user_ids to the specified the group_ids.
If a specified user_id is not in the group user list, an error is issued and processing continues with the remaining user_ids.
A user cannot be dropped from a group if that group is the default group of the user. Use the ALTER USER statement to change a user's default group.
If a user is dropped from a group in a session that is associated with that group, the user retains the privileges of the group until the session terminates.
DROP ALL
Removes all users from the specified group_ids.
If any member of the specified group has that group as its default group, DROP ALL results in an error. Use the ALTER USER statement to change the user's default group.
If a user is dropped from a group in a session that is associated with that group, the user retains the privileges of the group until the session terminates.
