sql - SELECT COL1+COL2 as CalcColumn,* FROM TABLE WITH (NOLOCK) WHERE 100<COL1+COL2 -

-

in select statement using condition based on calculated value, possible include calculated value without computing calculated value twice - once in selection , again in condition?

i using sql server 2000.

you put subquery , select that

sql statement

select *   (          select col1 + col2 calccolumn            table        ) q  100 < calccolumn

but performance, expect slower original query.
