Responding to devendra_joshi:



In DB2 Universal Database for Linux, UNIX, and Windows the catalog views are accessed through the SYSCAT schema, not the SYSIBM schema -- so you should be issuing "SELECT * FROM SYSCAT.KEYCOLUSE" to list all of the columns that participate in a given key constraint.



A complete list of the catalog views for DB2 can be referenced at http://publib.boulder.ibm.com/infocenter/db2help/ by searching for 'catalog views' and selecting the top hit.

Sample to get the primary keys of an MSSQL table:



$cn = odbc_connect( "DSN", "sa", "pwd");



$rs = odbc_primarykeys( $cn, "database", "dbo", "table_name"); 



odbc_result_all($rs);

I want a list of primary keys of a table in db2



by using 

'select * from SYSIBM.SYSKEYCOLUSE ' query i am getting the result on CLP

but when i am writing it in PHP as follows it returns 0 ROWS.



$mstmt="select * from SYSIBM.SYSKEYCOLUSE";

$b=odbc_exec($conn,$mstmt);

echo odbc_result_all($b);



where as  if we write this code



$mstmt="select * from SYSIBM.SYSFUNCTIONS";

$b=odbc_exec($conn,$mstmt);

echo odbc_result_all($b);



it returns the correct data.
