Supported drivers and connection strings

Synapse SQL supports ADO.NET, ODBC, PHP, and JDBC. To find the latest version and documentation, select one of the preceding drivers. To automatically generate the connection string for the driver that you're using from the Azure portal, select Show database connection strings from the preceding example. Following are also some examples of what a connection string looks like for each driver.


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

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);
