Code:


select colname from sysibm.sysforeignkeys where tbname = 'table name';



will give you the col which is the foreign key

now for primary key

select colname from sysibm.syskeys where ixname in
(select name from sysibm.sysindexes where tbname ='table name');

you may get the details of the primary key with the following query as well :

SELECT NAME FROM SYSIBM.SYSCOLUMNS WHERE TBCREATOR = <TABLE CREATOR NAME> AND TBNAME = <TABLE NAME> AND KEYSEQ > 0;

(OR)

SELECT A.COLNAME, A.COLSEQ, A.ORDERING, FROM SYSIBM.SYSKEYS A, SYSIBM.SYSINDEXES B WHERE A.IXNAME = B.NAME AND A.IXCREATOR = B.CREATOR AND A.IXCREATOR = B.TBCREATOR AND B.TBNAME = <TABLE NAME> AND B.TBCREATOR = <TABLE CREATOR> AND B.UNIQUERULE = ā€˜Pā€™;
