This is the scenario:
I have an .aspx page where the user inserts the days (integer) and other 2 criteria, then I send this data to an storeprocedure to do the filter and show the data:

      @Dias int,
      @TipoEmpleo varchar(50),
      @Localidad varchar(50)
      
      
      AS

      SELECT * FROM Ofertas WHERE TipoEmpleo = @TipoEmpleo AND UbicacionEmpleo = @Localidad AND Fecha > (Fecha - @Dias)

I need help with the  DateTime field (Fecha), I need the storeprocedure filter using the data is stored into “Fecha” less the integer data is stored into @Dias.

Thank you
Regards

You do know that Fecha is always greater than Fecha - @Dias. In other words Today is always greater than Today less 3 days.
However, using that logic. I would do something like this:
SELECT * FROM Ofertas WHERE TipoEmpleo = @TipoEmpleo AND UbicacionEmpleo = @Localidad AND Fecha > DateAdd(Day, -@Dias, Fecha)

I was reviewing this... I did the changes you  suggest me, but it looks than the query do nothing, the issue is in here:

Fecha > DateAdd(Day, -@Dias, Fecha)

What I saw, we are comparing "Fecha" with "Fecha" -@Dias...

what we should compare is "Today" with "Fecha" -@Dias...

so, my question now would be how to get "Today" on sql??

SELECT * FROM Ofertas
WHERE TipoEmpleo = @TipoEmpleo
AND UbicacionEmpleo = @Localidad
AND Fecha > dateadd(d, -@Dias, getdate())

-- returns all records where Fecha is less than @Dias days old
-- getdate() includes the time portion so if you search at Aug 22 12:30, the query is actually

AND Fecha > 'Aug 20 12:30'
