lock a table in sql server 2008 after select

问题

I have a main currency table. Which has two fields, one currency Type and currency value. User can not be changed once a user start working with the DB. I need to lock my Currency table through SQL Server 2008 Query once user select one value. Can any one help me or suggest me for DB LOCK query.

回答1:

You can use NOLOCK for your objects.

For example :

SELECT TOP 10 * FROM Orders WITH(NOLOCK) where UserName = 'VadaVici'

We had the same problem on a table in our database. Found this and it worked for us:

SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
SELECT * FROM dbo.MyTable WITH (TABLOCKX);

The table will be locked until a COMMIT TRANSACTION or ROLLBACK TRANSACTION is executed.

Hope it helps somebody in the future...
