Microsoft SQL Server Connections

You can create connections to 1 or more Microsoft SQL Server databases from Alteryx Analytics Cloud (AAC).

Sugerencia

You can create connections to databases of this type that are managed by your enterprise or are hosted in cloud infrastructure. The required configuration is the same. The cloud-based version is labeled on Amazon RDS. In the Create Connection dialog, you can search for that term.

If you are connecting AACAAC to any relational source of data, you must add the Alteryx Service to your allowlist for those resources. See Allowlist Platform Service.

Supported Versions: The product uses the 11.2 JDBC driver for SQL Server-based connection types. For more information, see https://learn.microsoft.com/en-us/sql/connect/jdbc/microsoft-jdbc-driver-for-sql-server-support-matrix?view=sql-server-ver16#sql-version-compatibility.

Connection Description

Description of the connection, which appears in the application.

Connection URL

The properties that you provide are inserted into the following URL, which connects AACAAC to the connection:

jdbc:sqlserver://<host>:<port>;<prop1>=<val1>;<prop2>=<val2>

Connect string options

The connect string options are optional. If you are passing additional properties and values to complete the connection, the connect string options must be structured in the following manner:

;<prop1>=<val1>;<prop2>=<val2>...

where:

  • <prop> : the name of the property

  • <val> : the value for the property

delimiters:

  • ; : any set of connect string options must begin and end with a semi-colon.

  • = : property names and values must be separated with an equal sign (=).

Example connect string options

The following connect string contains several options. Please insert as a single string (no line breaks):

;database=<database_name>;encrypt=true;trustServerCertificate=false;
hostNameInCertificate=*.database.windows.net;loginTimeout=30;
