PDOStatement::errorCode

Statement's errorCode() returns an empty string before execution, and '00000' (five zeros) after a sucessfull execution:<?php$stmt = $pdo->prepare($query);assert($stmt->errorCode === '');$stmt->execute();assert($stmt->errorCode === '00000');?>

Neither this property nor the PDOStatement::errorInfo() properties are available if you create  your own exception handler.I am using PHP 5.2.4, PDO_INFORMIX 1.2.0.Making this call at any point in the program after setting your own exception handler produces an error:PHP Notice:  Undefined property:  PDOStatement::$errorCode in new_query.php on lineorPHP Notice:  Undefined property:  PDOStatement::$errorInfo in new_query.php on lineBut if I set the PDO to SILENT, only set error codes with:$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_SILENT)Then process with if/else the call to this functions works fine.  The examples below only do error checking to show the result codes of this function.  Normally you would want more.FAILS:$dbh = new PDO("informix...")$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);try  {      $result = $dbh->query("asdfkjasdfkjasdfjk");  /* obvious sql error */      if ($result) print "success!";      }catch      {      $myeCode = $dbh->errorCode();      /* do stuff with error */      };$dbh=0;The error handler gets called but knows nothing about $dbh->errorCode or $dbh->errorInfo.WORKS:$dbh = new PDO("informix...")$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_SILENT);$result = $dbh->query("asdfkjasdfkjasdfjk");  /* obvious sql error */if ($result)       {      /* process result */      print "success!";      /* all done, didn't make any changes */      $dbh->rollback();      }else      {      $myeCode = $dbh->errorCode();      print_r($myeCode);      };$dbh=0;  /* close connection */I hope this helps someone else.Cheers,David
