ODBC and SQLCA

Hi! I'm writing a mysql<->odbc compatiblity class in PHP, but to implement the mysql_affected_rows() function I need to be able, through ODBC (using DB2 now), to get the SQLCA variables, which among other things hold the number of (estimated if a prepared statement) affected rows by, say, an UPDATE statement.. Anyone know how to do this? Any help appreciated.. -Eirik Overby Freepoint Networks GmbH Hamburg, Germany
