Create Group Statement
The create group statement establishes a group identifier and associates it with the specified list of users. Group identifiers enable the database administrator (or user that has the security privilege) to grant identical privileges to a group of users. For a complete discussion of group identifiers and their use, see the Ingres Database Administrator Guide.
After creating a group identifier and specifying its members, the system administrator can grant privileges to the group identifier. When a member of the group begins a session, the group identifier can be specified in the sql or connect statement (or on the operating system command line, using the -G flag) to obtain the privileges associated with the group. For more information, see the Ingres SQL Reference Guide.
This statement has the following syntax:
create group group_id {, group_id}
[with users = (user_id {, user_id})];
Parameters--Create Group Statement
This statement has the following parameters:
group id
Is the group identifier. It must be a valid object name that is unique among all user, group, and role identifiers in the installation. If an invalid identifier is specified in the list of group identifiers, the DBMS Server returns an error but processes all valid group identifiers. Group identifier names are stored in the iiusergroup catalog in the iidbdb database.
user id
Must be a valid user name. If an invalid user identifier is specified, the DBMS Server issues an error but processes all valid user identifiers. A group can contain any number of users. A group identifier can be created without specifying a user list. To add users to an existing group identifier, use the alter group statement (see
Alter Group Statement).
Create Group Permissions
You must have MAINTAIN_USERS privilege and be connected to the iidbdb database.
Create Group Locking
The create group statement locks pages in the iiusergroup catalog in the iidbdb. This can cause sessions attempting to connect to the server to be suspended until the create group statement is completed.
