Hi,

I would like to know how to retrive indexes of a table.
i had gone through some of the previous posts and found only one information.

SYSIBM.SYSKEYS
is the table. it has following columns
Code:
IXNAME VARCHAR(18)
IXCREATOR CHAR(8)
COLNAME VARCHAR(18)
COLNO SMALLINT
COLSEQ SMALLINT
ORDERING CHAR(1)
IBMREQD CHAR(1)

I do not know the index names. The only information i have is the table name. Let me know if some has any idea on this.

The table containing the indexes is SYSIBM.SYSINDEXES:
Code:
SELECT * FROM SYSIBM.SYSINDEXES
    WHERE TBNAME = 'tablename'
You receive one row for each index with a lot of nice information!
From there you can reach SYSIBM.SYSKEYS:
Code:
SELECT * FROM SYSIBM.SYSKEYS
    WHERE IXNAME IN (SELECT NAME
        FROM SYSIBM.SYSINDEXES
        WHERE TBNAME = 'tablename')
    ORDER BY IXNAME,COLSEQ
