Re: utcgetdate - stop a query after x time

Rob, you're right ... that's what I get for doing a drive-by shooting ...*arg*

---------------

Hmmmm, and rolling this into a where/SARG clause it looks like the query engine does halt processing of rows once the time limit has been hit.

====================

-- let run to completion

select convert(varchar,dbo.f_getdate(so.id),109)

from sysobjects so, syscolumns

go

     200K rows, cpu = 7500ms, logical IOs = 1,830

     table/index accesses = ~400K each

-- let run for 2 seconds

select convert(varchar,dbo.f_getdate(so.id),109)

from sysobjects so, syscolumns

where dbo.f_getdate(so.id) <= dateadd(ss,2,getdate())

go

     55K rows, cpu = 2000ms, logical IOs = 200

     table/index accesses = ~110K each

====================
