Notes
Corresponding System Authorities: GRANT and REVOKE statements assign and remove system authorities for SQL objects. The following table describes the system authorities that correspond to the SQL privileges:
SQL Privilege | Corresponding System Authorities when Granting to or Revoking from a Global Variable |
---|---|
ALL (Grant or revoke of ALL grants or revokes only those privileges the authorization ID of the statement has) | *OBJALTER |
ALTER | *OBJALTER |
READ | *OBJOPR |
WRITE | *OBJOPR |
WITH GRANT OPTION | *OBJMGT |
Corresponding System Authorities When Checking Privileges to a Global Variable: The following table describes the system authorities that correspond to the SQL privileges when checking privileges to a global variable. The left column lists the SQL privilege. The right column lists the equivalent system authorities.
SQL Privilege | Corresponding System Authorities |
---|---|
ALTER | *OBJALTER |
READ | *OBJOPR and *EXECUTE and *READ |
WRITE | *OBJOPR and *EXECUTE and |
