Retrieves extended error information of the most recent operation on the database handle.


array PDO::errorInfo();  

Return Value

An array of error information about the most recent operation on the database handle. The array consists of the following fields:

  • The SQLSTATE error code.

  • The driver-specific error code.

  • The driver-specific error message.

If there is no error, or if the SQLSTATE is not set, then the driver-specific fields are NULL.


PDO::errorInfo only retrieves error information for operations performed directly on the database. Use PDOStatement::errorInfo when a PDOStatement instance is created using PDO::prepare or PDO::query.

Support for PDO was added in version 2.0 of the Microsoft Drivers for PHP for SQL Server.


In this example, the name of the column is misspelled (Cityx instead of City), causing an error, which is then reported.

$conn = new PDO( "sqlsrv:server=(local) ; Database = AdventureWorks ", "");  
$query = "SELECT * FROM Person.Address where Cityx = 'Essen'";  
print $conn->errorCode();  
echo "\n";  
print_r ($conn->errorInfo());  

Additional ODBC messages

When an exception occurs, the ODBC Driver may return more than one error to help diagnose problems. However, PDO::errorInfo always shows only the first error. In response to this bug report, PDO::errorInfo and PDOStatement::errorInfo have been updated to indicate that drivers should display at least the following three fields:

0	SQLSTATE error code (a five characters alphanumeric identifier defined in the ANSI SQL standard).
1	Driver specific error code.
2	Driver specific error message.

Starting with 5.9.0, the default behavior of PDO::errorInfo is to show additional ODBC errors, if they are available. For example:

try {
    $conn = new PDO("sqlsrv:server=$server;", $uid, $pwd);
    $stmt = $conn->prepare("SET NOCOUNT ON; USE $database; SELECT 1/0 AS col1");
} catch (PDOException $e) {

Running the above script should have thrown an exception, and the output is like this:

array(6) {
  string(5) "01000"
  string(91) "[Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Changed database context to 'tempdb'."
  string(5) "22012"
  string(87) "[Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Divide by zero error encountered."

If the user prefers the previous way, a new configuration option pdo_sqlsrv.report_additional_errors can be used to turn it off. Simply add the following line in the beginning of any php script:

ini_set('pdo_sqlsrv.report_additional_errors', 0);

In this case, the error info shown will be like this, when running the same example script:

array(3) {
  string(5) "01000"
  string(91) "[Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Changed database context to 'tempdb'."

If necessary, the user may choose to add the following line to the php.ini file in order to turn off this feature in all their php scripts:

pdo_sqlsrv.report_additional_errors = 0

Warnings and errors

Beginning with 5.9.0, ODBC warnings will no longer be logged as errors. That is, error codes with prefix "01" are logged as warnings. In other words, if the user wants to log errors only, update the php.ini like this:

pdo_sqlsrv.log_severity = 1

In this case, the log file will not contain any warning message(s). Please check how logging works for pdo_sqlsrv users.
