O.K Let me ask my question another way . I have a table which I need to
sum it's two fields on every update , every insert , every delete. To make
things faster I prepared a Master - Detail Dataset. I put the totals on
master. Every time I update the child table I go to master table and update
the totals. Is there another way to do this ? like using a query every time
to get the totals of child fields , or using a SP or using a Trigger or
something else ? Then what will be the advantages and disadvantages of
these ?
