odbc_primarykeys

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);

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.

I want a list of primary keys of a table in db2by using 'select * from SYSIBM.SYSKEYCOLUSE ' query i am getting the result on CLPbut 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.

I was trying to find the primary keys from an SQLServer database through the ODBC interface.  Funnily enough, the odbc_primarykeys function doesn't work with SQLServer (at least not my implementation of it).  Fortunately, the sp_keys query is passed through and the answer returned.  This code works (providing you know which database you're dealing with, which is a whole 'nother story).// If this is SQLServer, we need to do a special operation to get the// primary keys.//// Looks like the implementers of the ODBC interface just blew this// one off, since the database has a query to return the info and the// info even comes back with the same column names.if ($DBType == "SQLServer")  $KeySel = odbc_exec($DBConn, "sp_pkeys ".$TableName);// Otherwise, ask the database through ODBC for the primary key// names.else $KeySel = odbc_primarykeys($DBConn, $DatabaseName,  $DatabaseUser, $TableName);while ($KeySel && ($KeyRec = odbc_fetch_array($KeySel)))  $KeyCol[$KeyRec["KEY_SEQ"]] = $KeyRec["COLUMN_NAME"];
