How to make this simple SELECT query perform faster

Hi,

I have the following simple SELECT query:

SELECT * FROM TRX_LAPD

But the problem that table TRX_LAPD is very big. Althoug, I am using this query in a Network envirenment.

If I implement this query inside Microsoft SQL Server, the first time is somehow slow (40 sec), but becasue of the caching cabability the next time is very fast.

The thing that I am using this query in Visual Web Developer, so to be accessed by other users in the local network, but it seems that there is no caching features; each time I execute the query the implementation remains slow (40 sec) even from the from the server PC which have the SQL Server running.

I used also a simple Stored Procedure, but nothing changed

Below my code in Visual Web Developer with VB script:

Sub getmytable()
Dim sql As String
sql = "SELECT * FROM TRX_LAPD"
'or sql = "EXEC getTRX_LAPD" if I will use the Stored Procedure

MySqlDataSource.SelectCommand = sql
'where MySQLDataSource is an SqlDataSource control
End Sub

and the Stored Procedure that I tried also:

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go

ALTER PROCEDURE [dbo].[getTRX_LAPD]
AS
BEGIN
SET NOCOUNT ON;
SELECT * FROM TRX_LAPD
END

The SqlDatasource is bounded to a GridView control
I really appreciate any help.
Thanks

There are two basic rules of querying a database table:

1. Query only the rows that you need.
2. Query only the columns that you need.

By doing "SELECT * FROM TRX_LAPD", you are retreiving all the rows and all the columns all the time. Is that really a necessity? If you are doing this on a "very big" table (as you as say) it is bound to take time. I suggest you should revisit the design of querying the entire table every time.
