Hi,

I've a DB2 Table and would like to know if there is any wayto find out the programs which are accessing the table(including the type of operation like Select,Update,Insert,Delete).

We have around 220 tables and this info will reduce our manual scan.

Thanks in advance
Sree

for static sql, suggest you run this once without where clauses
to get an idea of what you actually want to display,
then add the appropriate where clauses.
my system, GRANTEE is program/plan name.

Code:

    SELECT  SUBSTR(GRANTEE,1,15) AS GRANTEE                             
          , SUBSTR(STNAME,1,20) AS STNAME                               
          , CASE DELETEAUTH                                             
              WHEN 'Y' THEN 'D'                                         
              ELSE ' '                                                 
            END AS DEL                                                 
          , CASE INSERTAUTH                                             
              WHEN 'Y' THEN 'I'                                         
              ELSE ' '                                                 
            END AS INS                                                 
          , CASE SELECTAUTH                                             
              WHEN 'Y' THEN 'S'                                         
              ELSE ' '                                                 
            END AS SEL                                                 
          , CASE UPDATEAUTH                                             
              WHEN 'Y' THEN 'U'                                         
              ELSE ' '                                                 
            END AS UPD                                                 
          , GRANTEDTS                                                   
    FROM SYSIBM.SYSTABAUTH                                             
    WHERE COLLID IN ('your collection ids'                                           
                    ,'your collection ids'                                         
                    )                                                   
--      AND SUBSTR(GRANTEE,1,3) NOT IN ('and anything you want to exclude', 'other exclusions')                     
    ORDER BY STNAME                                                     
           , GRANTEE                                                   
           , GRANTEDTS                                                 
    ;

I've one more question, are these tables updated instantly? I mean when I change a program to remove queries related to a table and bind it, will this catalogue table updated immediately?

Yes it will. The Bind updates several catalog tables, SYSTABAUTH among them.

depending on your system:
a new precompile/bind will generate a new VERSION of the package and thus a new CONTOKEN.
which means you'll get 2 entries in syspackage and systabauth for the same program.
