“Invalid column name” error on SQL statement from OpenQuery results

Question

I\'m trying to perform a SQL query through a linked SSAS server. The initial query works fine:

SELECT \"Ugly OLAP name\" as \"Value\" 
FROM OpenQuery( OLAP,         


        

Answer 1

This should work:

SELECT A.Value
FROM (
SELECT "Ugly OLAP name" as "Value" 
FROM OpenQuery( OLAP, 'OLAP Query')
) AS a
WHERE a.Value > 0

It's not that Value is a reserved word, the problem is that it's a column alias, not the column name. By making it an inline view, "Value" becomes the column name and can then be used in a where clause.
