with nolock problem

Hi,
Is there a way to catch every select comming to sql and change it to
select with nolock?
or how to make database READ UNCOMMITTED permanent?
any ideas?

If there are no updates in the database, you can set it to READONLY, to
avoid the overhead of locking. But apart from that, there is no option to
do this on database level.

However, the application could issue SET TRANSACTION ISOLATION LEVEL
READ UNCOMMITED when it connects.

But I would definitely think twice before I took such a step. If you
have issues with blocking, maybe you should rather review indexing
than resorting to NOLOCK.

I wondering which one of the following I should use to get the best performance. 1. "SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED" OR 2. "WITH (NOLOCK)" I notice that when I use the #1 "SET TRANSACTION..." it sets a lock Mode type of "Sch-S" (Schema stability Lock) which described by SQL Books Online as "Schema stability (Sch-S) locks do not block any transactional locks, including exclusive (X) locks"

Hello all, I'm using SS2K on W2k. I'v got a table say, humm, "Orders" with two fields in the PK: OrderDate and CustomerID. I would like to add an "ID" column which would be auto-increment (and would be the new PK). But, I would really like to have orders with the oldest OrderDate having the smallest ID number and, for a same OrderDate, I'd to have the smallest CustomerID first. So my question is:

I have a combo box where users select the customer name and can either go to the customer's info or open a list of the customer's orders. The RowSource for the combo box was a simple pass-through query: SELECT DISTINCT , , ,City, Region FROM Customers ORDER BY Customers.; This was working fine until a couple of weeks ago. Now whenever someone has the form open, this statement locks the entire Customers table.

I have a Store Procedure on a Sql Server 2000 Where I use the Table Hint "NoLock" on all selects. One of my clients (OleDbConnection from C#) doesn't get the same Result Set as the others. The result Set should have 31 rows but this client only gets 5! When I remove all the "NoLocks" everything works fine. How can that be?
