pdo

问题 I want to use Doctrine2 ORM in my php application. For DB2, Doctrine2 supports only pdo_ibm and ibm_db2 drivers. I installed a local instance of DB2 (DB2 Express-C) and conneceted with pdo_ibm and ibm_db2 successfully and even using the local db2 instance my doctrine2 installation works fine and is functional, but my real aim is to connect to a remote DB2 instance running on a i5/os. Remote connections to this (remote) DB2 works only using odbc and PDO_ODBC but fails with pdo_ibm and ibm_db2

After 10 seconds it will check again and now it will check if the id of the row is the same as
