The solution is to use SYSTABAUTH table. Assume the table name is ‘DB1T04’ and we want to find out what all programs performs C(CREATE) R(READ) U(UPDATE) or D(DELETE) operation. A simple query to fetch the matrix would like below:

SELECT SUBSTR(TCREATOR,1,10) AS CREATOR
, SUBSTR(TTNAME,1,10) AS NAME
, SUBSTR(GRANTEE,1,10) AS PROGRAM
, CASE WHEN INSERTAUTH = 'Y' THEN 'C'
ELSE '-'
END AS C
, CASE WHEN SELECTAUTH = 'Y' THEN 'R'
ELSE '-'
END AS R
, CASE WHEN UPDATEAUTH = 'Y' THEN 'U'
ELSE '-'
END AS U
, CASE WHEN DELETEAUTH = 'Y' THEN 'D'
ELSE '-'
END AS D
, CASE WHEN COLLID = ' ' THEN '** PLAN **'
ELSE COLLID
END AS "PLAN/COLLECTION"
, CASE WHEN CONTOKEN = ' ' THEN CONTOKEN
ELSE HEX(CONTOKEN)
END AS TOKEN
FROM SYSIBM.SYSTABAUTH
WHERE TTNAME = 'DB1T04'

o/p will be generated as :

The program names will be shown along with the operation it does on the table.
