 How to have a IF statement in a nested select

I need a query to always give output irrespective if the table exists or not. If it doesn't exists it just returns no rows but does return the columns.
The query will be used in SQL Server Analysis Services as a fact table

I have the following query simplified

IF object_id('MyTable', 'U') is not NULL

Select ColA,ColB,ColC from MyTable
[ColA] [int] ,
[ColB] [nvarchar](30),
[ColC] [nvarchar](30) ,
Select * from MyTempTable

This query runs perfect outside analysis services.

However when I put it in analysis services fact table is equivalent to making the above query a nested select of
Select * from
//If select

I then get an error
Msg 156, Level 15, State 1, Line 5
Incorrect syntax near the keyword 'IF'.

because it doesn't like the if statement in the nested select.

Any possible way to put a nested if statement inside a subquery?

within a query, CASE is used instead of IF
