Connection strings for SQL pools in Azure Synapse

You can connect to a SQL pool in Azure Synapse with several different application protocols such as, ADO.NET, ODBC, PHP, and JDBC. Below are some examples of connections strings for each protocol. You can also use the Azure portal to build your connection string.

To build your connection string using the Azure portal, navigate to your SQL pool blade, under Essentials click on Show database connection strings.

Sample ADO.NET connection string

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

Sample ODBC connection string

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;

Sample PHP connection string

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);

Sample JDBC connection string



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