How to: Retrieve Date and Time Types as PHP DateTime Objects Using the PDO_SQLSRV Driver

[!INCLUDEDriver_PHP_Download]

This feature, added in version 5.6.0, is only valid when using the PDO_SQLSRV driver for the [!INCLUDEssDriverPHP].

To retrieve date and time types as DateTime objects

When using PDO_SQLSRV, date and time types (smalldatetime, datetime, date, time, datetime2, and datetimeoffset) are by default returned as strings. Neither the PDO::ATTR_STRINGIFY_FETCHES nor the PDO::SQLSRV_ATTR_FETCHES_NUMERIC_TYPE attribute has any effect. In order to retrieve date and time types as PHP DateTime objects, set the connection or statement attribute PDO::SQLSRV_ATTR_FETCHES_DATETIME_TYPE to true (it is false by default).

Note

This connection or statement attribute only applies to regular fetching of date and time types because DateTime objects cannot be specified as output parameters.

Example - use the connection attribute

The following examples omit error checking for clarity. This one shows how to set the connection attribute:

<?php
$server = 'myserver';
$databaseName = 'mydatabase';
$username = 'myusername';
$passwd = '<password>';
$tableName = 'mytable';

$conn = new PDO("sqlsrv:Server = $server; Database = $databaseName", $username, $passwd);

// To set the connection attribute
$conn->setAttribute(PDO::SQLSRV_ATTR_FETCHES_DATETIME_TYPE, true);
$query = "SELECT DateTimeCol FROM $tableName";
$stmt = $conn->prepare($query);
$stmt->execute();

// Expect a DateTimeCol value as a PHP DateTime type
$row = $stmt->fetch(PDO::FETCH_ASSOC);
var_dump($row);

unset($stmt);
unset($conn);
?>

Example - use the statement attribute

This example shows how to set the statement attribute:

<?php
$database = "test";
$server = "(local)";
$conn = new PDO("sqlsrv:server = $server; Database = $database", "", "");
$query = "SELECT DateTimeCol FROM myTable";
$stmt = $conn->prepare($query);
$stmt->setAttribute(PDO::SQLSRV_ATTR_FETCHES_DATETIME_TYPE, true);
$stmt->execute();

// Expect a DateTimeCol value as a PHP DateTime type
$row = $stmt->fetch(PDO::FETCH_NUM);
var_dump($row);

unset($stmt);
unset($conn);
?>

Example - use the statement option

Alternatively, the statement attribute can be set as an option:

<?php
$database = "test";
$server = "(local)";
$conn = new PDO("sqlsrv:server = $server; Database = $database", "", "");

$dateObj = null;
$query = "SELECT DateTimeCol FROM aTable";
$options = array(PDO::SQLSRV_ATTR_FETCHES_DATETIME_TYPE => true);
$stmt = $conn->prepare($query, $options);
$stmt->execute();
$stmt->bindColumn(1, $dateObj, PDO::PARAM_LOB);
$row = $stmt->fetch(PDO::FETCH_BOUND);
var_dump($dateObj);

unset($stmt);
unset($conn);
?>

Example - retrieve datetime types as strings

The following example shows how to achieve the opposite (which is not really necessary because it is false by default):

<?php
$database = "MyData";
$conn = new PDO("sqlsrv:server = (local); Database = $database");

$dateStr = null;
$query = 'SELECT DateTimeCol FROM table1';
$options = array(PDO::SQLSRV_ATTR_FETCHES_DATETIME_TYPE => false);
$stmt = $conn->prepare($query, $options);
$stmt->execute();
$stmt->bindColumn(1, $dateStr);
$row = $stmt->fetch(PDO::FETCH_BOUND);
echo $dateStr . PHP_EOL;

unset($stmt);
unset($conn);
?>
