Hello Priya,
Execute the following query, you will get the primary key for the table
SYSIBM.SYSCOLUMNS identifies columns of a parent key in column KEYSEQ; a nonzero value indicates the place of a column in the parent key.
| Code: |
SELECT TBCREATOR, TBNAME, NAME, KEYSEQ
FROM SYSIBM.SYSCOLUMNS
WHERE TBCREATOR = 'creater id'
AND TBNAME = 'table-name'
AND KEYSEQ > 0
ORDER BY KEYSEQ; |
SYSIBM.SYSINDEXES identifies the primary index of a table by the value P in column UNIQUERULE.
| Code: |
SELECT TBCREATOR, TBNAME, NAME, CREATOR, DBNAME, INDEXSPACE
FROM SYSIBM.SYSINDEXES
WHERE TBCREATOR = 'creator id'
AND TBNAME = 'table-name'
AND UNIQUERULE = 'P'; |
Hope this will help you.
Regards
Mayuresh Tendulkar

While selecting all columns of a table,
It displayed in ASCNDING order of the primary key by default. (If you have any other parallel row in asc order, just try by inserting two more rows in des order for all columns) |

Hello Priya,
Below is the answer of your query..
| Code: |
SELECT TBNAME, COLNAME, COLNO, CREATOR
FROM SYSIBM.SYSFOREIGNKEYS
WHERE TBNAME = 'table-name'; |
SYSFOREIGNKEYS table contains one row for every column of every foreign key.
Let me know if this helps you.
Regards

Dear priya,
To find the relative table of that foreign key, please use SYSIBM.SYSRELS |
