      Hi everyone,

       

      I'm trying to create a custom SQL

       

      And I'm getting the following error:

       

      An error occurred while communicating with the data source. Bad Connection: Tableau could not connect to the data source.

      com.tableausoftware.jdbc.TableauJDBCException: Error reading metadata for executed query: SELECT *

      FROM (

        select * from (table)

      ) "custom_sql_query"

      LIMIT 0

      Table not found. Please check your query.

      There was a Java error.

       

       

       

       

      My SQL-Statement: Select date from table where date = 2018 (Wrong Syntax ?)
