Authorization
For any form of a query, the privilege set that is defined below must include one of the following:
- For each table or view identified in the statement,
the privilege set must include one of the following:
- Ownership of the table or view
- The SELECT privilege on the table or view
- DBADM authority for the database (tables only)
- SYSADM authority
- SYSCTRL authority (catalog tables only)
DATAACCESS authority
- For each user-defined function that is identified in the statement,
one of the following:
- The EXECUTE privilege on the function
- Ownership of the function
- SYSADM authority
DATAACCESS authority
If the select-statement is part of a DECLARE CURSOR statement, the privilege set is the privileges that are held by the authorization ID of the owner of the plan or package.
If the select-statement contains an SQL data change statement, the privilege set must include the SELECT privilege and the appropriate privileges for the SQL data change statement (insert, update, or delete privileges) on the target table or view.
If
the select-statement references a table
that contain an active row or column access control, and row permissions
or column masks are defined for the table, the authorization ID or
role of the statement does not need authority to reference objects
that are specified in the definitions of those row permissions or
column masks.
For dynamically prepared statements, the privilege set depends on the dynamic SQL statement behavior, which is specified by option DYNAMICRULES:
- Run behavior
- The privilege set is the union of the privilege sets that are held by each authorization ID of the process.
- Bind behavior
- The privilege set is the privileges that are held by the authorization ID of the owner of the plan or package.
- Define behavior
- The privilege set is the privileges that are held by the authorization ID of the owner of the stored procedure or user-defined function.
- Invoke behavior
- The privilege set is the privileges that are held by the authorization ID of the invoker of the stored procedure or user-defined function.
For a list of the DYNAMICRULES values that specify run, bind, define, or invoke behavior, see Table 1.
When any form of a query is used as a component of another statement, the authorization rules that apply to the query are specified in the description of that statement. For example, see CREATE VIEW for the authorization rules that apply to the subselect component of CREATE VIEW.
If your installation uses the access control authorization exit (DSNX@XAC), that exit might be controlling the authorization rules instead of the rules that are listed here.
