Didn´t you found anything here in codeproject?

Do you want do match/join contents from diferent tables and display it?
try inner join in search code project.

Create procedure sp_Fetchrecords<br />
@tbname sysname=NULL<br />
AS<br />
Select * from @tbname<br />
go<br />

check the store procedures folder if it is already there!
use alter procedure to change it.

i usualy set the database on which i write on sql server up-left corner combobox. i don´t not use code but you can do that, do you need to code that?

create procedures like this (with inner join)
--------------sp-----------

create procedure vendas_criadas

@data_ini as smalldatetime,
@data_fim as smalldatetime

as

begin

select ve.id_venda as 'ID Venda',al.nome as 'Album',cl.primeiro_nome+' '+cl.ultimo_nome as 'Cliente',ut1.primeiro_nome+' '+ut1.ultimo_nome as 'Criador',ve.id_utilizador_criador_data as 'Data Criação'
from dbo.vendas as ve
inner join dbo.albuns as al on ve.id_album = al.id_album
inner join dbo.clientes as cl on ve.id_cliente = cl.id_cliente
inner join dbo.SPY_utilizadores as ut1 on ve.id_utilizador_criador = ut1.id_utilizador
where ve.data_registo between @data_ini and @data_fim

end

go

-------------execute-------------------

exec vendas_criadas
@data_ini = '1/1/2007',
@data_fim = '1/1/2008'

Create procedure sp_Fetchrecords
@tbname sysname=NULL
AS
SET NOCOUNT ON
IF @tbname IS NOT NULL 
BEGIN
	DECLARE @cmd NVARCHAR(4000)
	SET @cmd = 'Select * from '+@tbname
	EXEC(@cmd)
END
go

I just realized there was the second one. The second one sets a variable that is the sql string, and the exec(...) executes the sql string.

You could get really fancy with this stored proc, such as adding where clause, and order by as parameters into the stored proc, and add them to the @cmd variable.
