Deepak,
You can use builtin tables such as SYSIBM.SYSCOLUMNS, SYSIBM.SYSFIELDS, place the table name in where caluse and check it.
| Code: |
| Eg: SELECT * FROM SYSIBM.SYSCOLUMNS WHERE TBNAME = 'EMP'; |
Note : Use the above query in QMF, bcz when i try it in ISPF it was not listed in detail. try and let me know if you need more. |
