SQL Server doesn't offer any support for that. If you want to pass messages between applications, and have them persist in the case of software or hardware failure, Microsoft's solution is Microsoft Message Queueing[^].
The temporary table is one solution, but do remember that true temporary tables (named with a # or ## prefix) are stored in tempdb, which is not persisted across SQL Server runs. It is recreated from scratch every time SQL Server starts up. I believe it is also recreated whenever a SQL Server cluster fails over to a different node, though I'm not sure about that.
SQL Server 2005 and .NET Framework 2.0 offer the SqlDependency class, which can be used to send a query to the database and the database to then call the application back when the results of that query would change. For more information, look up "query notifications" in the index in Books Online.

Thanks for the reply. We are actually using Oracle and VC 6 services and table is not actually temporary, it is simple table but data in it is only stored for message passing and then removed. I just wanted to know whether there is any better solution but it seems like our solution is the best we can get as we cannot modify first application.

What sort of attack are you envisioning?
SQL Server 2000, and it successors are designed to run in a server environment. The access to the machines they are running on should be restricted. The servers will normally be in a secured server room.

My guess is that he's concerned that some one might make a copy of the database files and run with them.

That would solve his problem...

i am not thanking of that
that is good but that a small thanking some Project like windows base- application (accounting for small company) small to run @ server that make some developer set up sqlserver2000 to the local computer to the company
so that open the data base for any developer
A developer usually has rights to the database anyway. They are supposed to be sufficiently trusted for such access.

Hi,
I need a help about deletion of records.
I am using MS acces, and using recordset.Addnew() to add records into a table.if iam going on adding records it is adding at end only and the order of records is fine..but if i delete some existing records bu using recordset.Delete(), and then add some records the order is shuffling, and the new records are not added at end. Can anyone explain why it is happening and a solution for the records in order.
Thanks for suggestions
Regards

Not sure, it sounds like Access is placing the data where ever it feels like it. Shouldn't really matter from a developer's stand point, as long as the logical correctness of your application is in place.

What happens if data is deleted? You will end up with rows with the same sequence number.
The efficient way of doing this is to make column an IDENTITY column that starts at 1 with an increment of 1. If you delete data, however, it will no longer be based on the number of rows as it is based on an increment since the last insert.

Hi,
I have a description column in database in which description is storing. I want to retrive only initial words.
|
|
|
|
|
How many words? Assuming that the word boundary is a white-space character, you could do some string manipulation with the CHARINDEX and SUBSTRING functions to find the nth word boundary character and then select all the text up to but not including that character.
However this seems more like an issue of flawed design. Consider storing the short description for your text in a separate column rather than deriving it from your long description if you need to query on it often.

Create a DTS task in SQL Server that deletes these records based on the expiry date. Then, you create a job that wraps the task and schedule it to run every day. I don't have SQL Server 2000 installed anymore so I can't give you the exact steps, but it's easy enough to figure out with the aid of Books Online.

You can create a trgger on insert if this table is not large or heavy used
CREATE TRIGGER trg_DelOldRec
AS
DELETE FROM [tbl name] WHERE DateCreated < DATEADD(mm, -3,GETDATE())

I would not ask for that at this website. Many of our contributors have written books. When you download a free book, it is basically stealing.

Unless the author allows a free watered down version of the book to be available. I don't know of very many who do.

I don't know why, but I get the feeling that website is putting up these books illegally. These are not free books.
