Use the table name in SYSINDEXES to get the Primary index

UNIQUERULE column in this table. Use this index name in
SYSKEYS table to get the column(s) in Primary key.

Answer / mani

Execute:

SELECT TBCREATOR, TBNAME, NAME, KEYSEQ
FROM SYSIBM.SYSCOLUMNS
WHERE TBCREATOR = 'creater id'
AND TBNAME = 'table-name'
AND KEYSEQ > 0
ORDER BY KEYSEQ

a nonzero value for KEYSEQ indicates the place of a column in
the primary key.
