Start Tableau and under Connect, select Amazon Redshift. For a complete list of data connections, select More under To a Server. Then do the following:
Enter the name of the server that hosts the database and the name of the database you want to connect to.
Enter the user name and password.
Ensure the Require SSL check box is not checked.
(Optional) Select Initial SQL 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.
Select Sign In.
If Tableau can't make the connection, verify that your credentials are correct. If you still can't connect, your computer is having trouble locating the server. Contact the Ease helpdesk
On the data source page, do the following:
(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.
From the Schema drop-down list, select the schema provided with your credentials.
Under Table, select a table or use the text box to search for a table by name.
Drag the table to the canvas, and then select the sheet tab to start your analysis.
