Supported drivers and connection strings

SQL pool works with various drivers. Select any of the following drivers for the latest documentation and version information: ADO.NET, ODBC, PHP, and JDBC.

You can automatically generate a connection string for your driver. Select a driver from the previous list and then select Show database connection strings.


Consider setting the connection timeout to 300 seconds to allow your connection to survive short periods of unavailability.

Here are examples of connection strings for popular drivers:

ADO.NET connection string example

Server=tcp:{your_server},1433;Database={your_database};User ID={your_user_name};Password={your_password_here};Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;

ODBC connection string example

Driver={SQL Server Native Client 11.0};Server=tcp:{your_server},1433;Database={your_database};Uid={your_user_name};Pwd={your_password_here};Encrypt=yes;TrustServerCertificate=no;Connection Timeout=30;

PHP connection string example

Server: {your_server},1433 \r\nSQL Database: {your_database}\r\nUser Name: {your_user_name}\r\n\r\nPHP Data Objects(PDO) Sample Code:\r\n\r\ntry {\r\n   $conn = new PDO ( \"sqlsrv:server = tcp:{your_server},1433; Database = {your_database}\", \"{your_user_name}\", \"{your_password_here}\");\r\n    $conn->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );\r\n}\r\ncatch ( PDOException $e ) {\r\n   print( \"Error connecting to SQL Server.\" );\r\n   die(print_r($e));\r\n}\r\n\rSQL Server Extension Sample Code:\r\n\r\n$connectionInfo = array(\"UID\" => \"{your_user_name}\", \"pwd\" => \"{your_password_here}\", \"Database\" => \"{your_database}\", \"LoginTimeout\" => 30, \"Encrypt\" => 1, \"TrustServerCertificate\" => 0);\r\n$serverName = \"tcp:{your_server},1433\";\r\n$conn = sqlsrv_connect($serverName, $connectionInfo);
