sql - Is there a way to set variables in a Select statement that can be used in the same statements WHERE clause? -


i'm looking way set variable in select statement can later used in where clause.

here example:

select datediff(d,time_stamp,getdate()) var1 report var1 = 5

i noticed order var1 clause, works fine, when try use in statement doesn't work fine, gives error on var1 column.

this doesn't work either because doesn't return rows.

declare @var1 int select @var1 = datediff(d,time_stamp,getdate()) report @var1 = 5

if make sense you, can tell me in case don't have write redundant code this...

select datediff(d,time_stamp,getdate()) report   datediff(d,time_stamp,getdate()) = 5

?

are looking this?

with qry (     select r.*, datediff(d,time_stamp,getdate()) diff       report r ) select * qry   diff > 1
