The PERMITRESET command causes the values of permission conditions to be reevaluated. Permission conditions consist of one or more Boolean expressions that designate the criteria used by PERMIT commands associated with an object.
When permission conditions are dimensioned, they indicate which values of a dimensioned object PERMIT will target for permission. A single-cell permission condition can indicate any Boolean criterion, such as whether or not a particular user may access the object.
When you want to keep the existing PERMIT commands for an object, but you want the permission conditions associated with them to be recalculated, issue a PERMITRESET statement. The permission for that object will be based on the new values of the permission conditions the next time you use the object in an OLAP DML statement.
Syntax
PERMITRESET [object_name] [READ|WRITE]
Arguments
Specifies the name of an object for which permission conditions should be reevaluated. When you do not specify an object name, the permission conditions for all objects are reevaluated.
Causes reevaluation of the permission conditions for PERMIT READ commands only, or for a PERMIT READ statement for the specified object.
Causes reevaluation of the permission conditions for PERMIT WRITE commands only, or for a PERMIT WRITE statement for the specified object.
Examples
Example 21-35 Resetting Permission
In the following example, the user-defined Boolean function usercheck checks the current value of the variable thisuser and returns YES only when it is greater than 100. Access to the variable uservar is only allowed when thisuser is greater than 100. However, when you change the value of thisuser to a value less than or equal to 100 without resetting the permission for uservar, access is still permitted.
The statement
DESCRIBE uservar
produces the following output.
DEFINE USERVAR VARIABLE INTEGER PERMIT READ WHEN usercheck(thisuser)
The statement
SHOW uservar
produces the following output.
5
The statement
DESCRIBE usercheck
produces the following output.
DEFINE USERCHECK PROGRAM BOOLEAN
PROGRAM
ARG thisuser INT
TRAP ON errorexit NOPRINT
IF thisuser GT 100
THEN RETURN YES
ELSE RETURN NO
errorexit:
RETURN NO
END
The statement
DESCRIBE thisuser
produces the following output.
DEFINE THISUSER VARIABLE INTEGER
The statement
SHOW thisuser
produces the following output.
101
The statements
thisuser = 100 SHOW uservar
produces the following output.
5
The statements
PERMITRESET luservar READ SHOW uservar
produce the following error.
ERROR: You do not have permission to read this value of USERVAR
