Hi I have a SQL Table:

VERSIONES_PLANOS
ID_PLANO varchar(20)
VERSION  smallint
ARCHIVO Image
THUMB  Image
DWF Image

And I have this data

id_plano : smt8
version:  0
archivo: <binary>
thumb: <binary>
dwf: <binary>

id_plano : smt8
version: 1
archivo: <binary>
thumb: <binary>
dwf: <binary>

I want to select * from versiones_planos where version = max(version)
but I dont know how to do the select sentence.

Thanks

Or simpler:

Select TOP 1 WITH TIES *
From VERSIONES_PLANOS
Order By VERSION DESC

Hi olgavillamizar,


Or something like this


Select VERSIONES_PLANOS, ID_PLANO, ARCHIVO, THUMB, DWF, Max(version) Version
FROM urTable
Group by VERSIONES_PLANOS, ID_PLANO, ARCHIVO, THUMB, DWF

Actually best for performance would be

Select TOP 1 WITH TIES *
From VERSIONES_PLANOS
Order By VERSION DESC

Perhaps, but only if that is what the questioner needs.  I get the distinct impression and reading between the lines that there is more to the question. We'll see or as the questioner may say "veremos"...
