You might already have the required driver installed on your computer. If the driver is not installed on your computer, Tableau displays a message in the connection dialog box with a link to the <a href="https://www.tableau.com/support/drivers" target="_blank">Driver Download<span class="sr-only">(Link opens in a new window)</span></a> page where you can find driver links and installation instructions.</p>&#13; <p class="note"><b>Note:</b> Beginning with Tableau 2020.4, you can connect to PostgreSQL 12 (or higher) databases from Tableau. A new JDBC driver for PostgreSQL supports these connections and is included with all Tableau products on Windows.<br/>On Linux and Mac computers, you'll need to install a driver for this connector when you use it with Tableau Desktop or Tableau Prep Builder.

For a complete list of data connections, select <span class="uicontrol">More </span>under <span class="uicontrol">To a Server</span>. Then do the following:</p>&#13; <p>Enter the name of the server that hosts the database that you want to connect to.</p>&#13; <p>Enter the name of the database.</p>&#13; <p>Select how you want to sign in to the server. Specify whether to use <span class="uicontrol">Integrated Authentication </span>or <span class="uicontrol">User Name and Password</span>. If the server is password protected, and you are not in a Kerberos environment, you must enter the user name and password.</p>&#13; <p class="note"><b>Note:</b> If you're using a Mac, and it is not attached to the domain correctly, the Mac won't know that Kerberos is being used in the domain, and the <span class="uicontrol">Authentication </span>drop-down list won't be available. </p>&#13; <p>Select the <span class="uicontrol">Require SSL</span> check box when connecting to an SSL server.</p>&#13; <p>(Optional) Select <span class="uicontrol">Initial SQL</span> to specify a SQL command to run at the beginning of every connection, such as when you open the workbook, refresh an extract, sign in to Tableau Server, or publish to Tableau Server.

If you still can't connect, your&#13; computer is having trouble locating the server. Contact your network&#13; administrator or database administrator.</p>&#13; <p>(Optional) Select the default data source name at the top of the page, and then enter a unique data source name for use in Tableau. For example, use a data source naming convention that helps other users of the data source figure out which data source to connect to.</p>&#13; <p>Under <span class="uicontrol">Table</span>, select a table or use the text box to search for a table by name.</p>&#13; <p>Starting with Tableau version 2019.2, you can connect to spatial columns. For more information, see <a href="maps_spatial_sql.htm" class="MCXref xref" xrefformat="{paratext}">Connect to Spatial Data in a Database</a>.</p>&#13; <p>Drag the table to the canvas, and then select the sheet tab to start your analysis.</p>&#13; <p> Use custom SQL to connect to a specific query rather than the entire data source.
