Actually above code is within the method and that method is being called in multiple places and it will return result-set... My problem is for some method calls its returning value but for other calls its giving empty result set... its not consistent across all calls also in log I check for any error randomly I get bellow error also ORA-03113: end-of-file on communication channel Session ID: 1168 Serial number: 37417 (DBD ERROR: OCIStmtExecute)
