# PDO::errorCode
[!INCLUDE[Driver_PHP_Download](../../includes/driver_php_download.md)]

PDO::errorCode retrieves the SQLSTATE of the most recent operation on the database handle.  
  
## Syntax  
  
```  
  
mixed PDO::errorCode();  
```  
  
## Return Value  
PDO::errorCode returns a five-char SQLSTATE as a string or NULL if there was no operation on the database handle.  
  
## Remarks  
PDO::errorCode in the PDO_SQLSRV driver returns warnings on some successful operations. For example, on a successful connection, PDO::errorCode returns "01000" indicating SQL_SUCCESS_WITH_INFO.  
  
PDO::errorCode only retrieves error codes for operations performed directly on the database connection. If you create a PDOStatement instance through PDO::prepare or PDO::query and an error is generated on the statement object, PDO::errorCode does not retrieve that error. You must call PDOStatement::errorCode to return the error code for an operation performed on a particular statement object.  
  
Support for PDO was added in version 2.0 of the [!INCLUDE[ssDriverPHP](../../includes/ssdriverphp_md.md)].  
  
## Example  
In this example, the name of the column is misspelled (`Cityx` instead of `City`), causing an error, which is then reported.  
  
```  
<?php  
$conn = new PDO( "sqlsrv:server=(local) ; Database = AdventureWorks ", "", "");  
$query = "SELECT * FROM Person.Address where Cityx = 'Essen'";  
  
$conn->query($query);  
print $conn->errorCode();  
?>  
```
