Connect to Synapse SQL

  • Article

Get connected to the Synapse SQL capability in Azure Synapse Analytics.

Important

Use Microsoft Entra authentication when possible. For more information, see Use Microsoft Entra authentication for authentication with Synapse SQL.

Find your server name

The server name for the dedicated SQL pool in the following example is: <server-name>.sql.azuresynapse.net. The server name for the serverless SQL pool in the following example is: <server-name>-ondemand.sql.azuresynapse.net.

To find the fully qualified server name:

  1. Go to the Azure portal.
  2. Select on Synapse workspaces.
  3. Select on the workspace you want to connect to.
  4. Go to overview.
  5. Locate the full server name.
    • For a dedicated SQL pool, use SQL Endpoint.
    • For the serverless SQL pool, use SQL on-demand endpoint.

Supported tools

Use Azure Data Studio or SQL Server Management Studio (SSMS).

For serverless SQL pools:

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.

Note

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

ADO.NET connection string example

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

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

ODBC connection string example

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

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

PHP connection string example

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

PHP 
Server: {your_server}.sql.azuresynapse.net,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}.sql.azuresynapse.net,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}.sql.azuresynapse.net,1433\";\r\n$conn = sqlsrv_connect($serverName, $connectionInfo);

JDBC connection string example

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

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

Connection settings

Synapse SQL standardizes some settings during connection and object creation. These settings can't be overridden and include:

Database Setting Value
ANSI_NULLS ON
QUOTED_IDENTIFIERS ON
DATEFORMAT mdy
DATEFIRST 7

Recommendations

For executing serverless SQL pool queries, recommended tools are Azure Data Studio and Azure Synapse Studio.
