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 select Show database connection strings.

This simple example uses SQL authentication, but Microsoft Entra authentication with ADO.NET is more secure and recommended.

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

This simple example uses SQL authentication, but Microsoft Entra authentication with ODBC is more secure and recommended.

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

This simple example uses SQL authentication, but Microsoft Entra authentication with PHP is more secure and recommended.

Server: {your_server}.database.chinacloudapi.cn,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}.database.chinacloudapi.cn,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}.database.chinacloudapi.cn,1433\";\r\n$conn = sqlsrv_connect($serverName, $connectionInfo);

This simple example uses SQL authentication, but Microsoft Entra authentication with JDBC is more secure and recommended.

jdbc:sqlserver://yourserver.database.chinacloudapi.cn:1433;database=yourdatabase;user={your_user_name};password={your_password_here};encrypt=true;trustServerCertificate=false;hostNameInCertificate=*.database.chinacloudapi.cn;loginTimeout=30;
