Question : T-SQL - Insert Column If True

Select
   a.Column1
   b.Column2
From
   Tbl1 a
   Tbl2 b
Where
   a.Column1 = b.Column1

If Column1 exists in Tbl2 I just want b.Colmun2 to = 'T', otherwise 'F'.  Taking away the statement above, basically, I just want to display a T or F column in the result if data exists in Tbl2. Thanks.
   

Answer : T-SQL - Insert Column If True

Try:

select a.column1,
case when exists (select * from tbl2 b where a.column1=b.column1) then 'T' else 'F' end as column2
from tbl1 a

Cheers,
