Tableau - Common Table Expression (CTE) SQL Server

问题

I am connecting Tableau with SQL Server and I am trying to use the T-SQL query. I just want to know, does Tableau support CTE (Common Table Expression)?

I came across this article and it said CTE is possible: http://kb.tableau.com/articles/howto/using-common-table-expressions

Here's my query:

WITH Test (Store) AS 
(
    SELECT 
        Store
    FROM
        FiscalReporting.dbo.LBR_STR_ORG
)
SELECT
    Store
FROM
    Test

When I am running this query, I get an error message. Please let me know if I am doing something wrong.

Most of my SQL queries are built with CTE. So it would be greatly appreciated if I get any help. Also, I am new to Tableau.

Thanks!

Tableau does not support CTE expressions in "Custom SQL". But it does in "Initial SQL".

Here are two examples, how to use it:

The solution involves using "Initial SQL" where you can create temp table (the one with # at the beggining - SQL Server) and then you refer to this temp table in your "Custom SQL"
