Hi!

I'm a spanish webdeveloper that make the website www.fametown.com, with a bigger pictures galleries.

I have a big problem in my SQL query that show the pictures... it need more than 20 seconds to complete. I found that here: "(F.IdPersonaje = 233) OR (F.IdPersonaje = 234)" its the problem. If i only select one F.IdPersonaje the query it's very very fast. But if i add OR... OR... OR... it's very slow. Can i use any alternative???

The website of this query is: http://www.fametown.com/sp/fotos.aspx?carpeta=victoriaadams&grp=5&debug=true

THANKS A LOT !!!

SELECT F.Id, C.Nick, F.Cpe, F.IdColaborador, F.Vistas, F.Nombre, F.Ruta, F.Ancho, F.Alto, F.Peso, F.Fecha, F.Puntos, F.NumVotos, P.Nombre As NombrePersonaje FROM Fotos F, Usuarios C, Personajes P WHERE F.Cpe < 60 AND ((F.IdPersonaje = 233) OR (F.IdPersonaje = 234)) AND F.IdColaborador = C.Id AND F.IdPersonaje = P.Id AND F.Id IN (SELECT TOP 1000 F.Id FROM Fotos F, Usuarios C, Personajes P WHERE F.Cpe < 60 AND ((F.IdPersonaje = 233) OR (F.IdPersonaje = 234)) AND F.IdColaborador = C.Id AND F.IdPersonaje = P.Id AND F.Id NOT IN (SELECT TOP 0 F.Id FROM Fotos F, Usuarios C, Personajes P WHERE F.Cpe < 60 AND ((F.IdPersonaje = 233) OR (F.IdPersonaje = 234)) AND F.IdColaborador = C.Id AND F.IdPersonaje = P.Id ORDER BY F.Fecha DESC, F.Nombre DESC, F.Id DESC) ORDER BY F.Fecha DESC, F.Nombre DESC, F.Id DESC) ORDER BY F.Fecha DESC, F.Nombre DESC, F.Id DESC

Try this

SELECT TOP 1000	f.Id,
		c.Nick,
		f.Cpe,
		f.IdColaborador,
		f.Vistas,
		f.Nombre,
		f.Ruta,
		f.Ancho,
		f.Alto,
		f.Peso,
		f.Fecha,
		f.Puntos,
		f.NumVotos,
		p.Nombre As NombrePersonaje
FROM		Fotos AS f
INNER JOIN	Usuarios AS c ON c.Id = f.IdColaborador
INNER JOIN	Personajes AS p ON p.Id = f.IdPersonaje
WHERE		f.Cpe < 60
		AND f.IdPersonaje IN (233, 234)
ORDER BY	f.Fecha DESC,
		f.Nombre DESC,
		f.Id DESC

This query run fast... but i need to do a script that can "paginate" the records. If i select 20 pictures in each page i need a query that take "1 to 20", "20 to 40", "40 to 60"....

Can you make this mod in your query. THANKS!!!
