ADS does not support table variables?

Question

For example, in Transact-SQL, I can declare a table variable like this:

DECLARE @MyTableVar table(  
    EmpID INT NOT NULL,  
    OldVacationHours INT,  
    NewVacationHours INT,  
    ModifiedDate datetime);

I'm using ADS 11. It looks like this version does not support table variables.

UPDATED

I looked at ADS 12, this version also does not support table variables.
