SQL

DECLARE @SUM AS INT --?
SET @SUM = 0
SELECT @SUM = @SUM + COLUMN_TO_AGGREGATE FROM MY_TABLE

And this is the most stupid way to do it - build in aggregate functions are much more faster...

using a variable in sql
Declare @Va as decimal.
set @Va=0

and query write like

select @Va=@Va+Columnname from Table
