If any user want to insert another row in that table then it is not possible message should be display....
Please Just reply the Query & CODE....

Why have you repeated this question a third time?
One of these days I'm going to think of a really clever signature.

A database does not display messages, it holds data. It holds data in bulk, not in "single records". What you want does not make much sense from a data-viewpoint.
Now, this is not the place to "order" code like you do. The questions on the forums are answered by volunteers, in their free time. Put it in a object, serialize it, and stuff it in a single-column blob.

Take a look at locking a table:

I didn't downvote you, but I think most people here won't like to do your work. You can ask questions, you can show your code and ask for help, but you have to do your work on your own. So my answer is:
Definitely not!

Try using something like:
select count(*) from MyTable
if (count = 0) then
do insert
else
fail
|
|
|
|
|
Why would you need a table with just 1 row?
|
|
|
|
|
Try an INSTEAD OF TRIGGER

Make sure the Primary Key can only contain 1 value using a check constraint:
ALTER TABLE [dbo].[MyTable] WITH CHECK ADD CONSTRAINT [CK_OneRow] CHECK (([Id]=(1)))

That is a very cool way to solve a very strange request. I'll give it a 5.

Super solution but can't be replicated in other databases like oracle.
Identity is a near equivalent to rowid concept in Oracle but its a dynamic value i.e not a sequence generator . Hence may be Only possible in sql server.

If you change the start value of the identity seed (I'm pretty sure this can be done) and truncate the table the hard coded 1 would fail  mind you it is a silly request in the first place and I suspect the OP does not even know what you are talking about.

It may not be as useless as it first appears. I have used this method to hold global variables that are used by more than one application.
|
|
|
|
|
It'd be easier to create a view and be done with it;
CREATE VIEW GlobalSettingsTable AS
SELECT 1 AS ColumnName,
2 AS Nanana,
'C:\Program Files'
|
|

|

Yes - if your values are constants.
|
|
|
|
|
No, also for dynamic values; you can put sub-selects in there, or even calls to managed code 
|
|
|
|
|
Don't get me wrong, I did not consider it useless (even in this idiotic context) just being a pedantic bastard.

Is ADO installed? The 32 or the 64-bit version?

No, it ain't. In fact, I'm gonna ignore the rest of the thread.

Hi,
Not sure it is the right forum...
I'm using VisualStudio 2010 and trying to use schema compare tool to deploy changes from my db project to my database (SQL server 2008).
when trying to deploy the changes I made in my db project I get anexception with the following message:
"Cannot create index. Object 'v_TQ_IFCR_DATA_COVERAGE' was created with the following SET options off: 'ANSI_NULLS, QUOTED_IDENTIFIER'."
If I will go the the index properties,I see that AnsiNulls
and QuatedIdentifiers are set to project default.
When changing those settings to ON I manage to deploy all updates without any exception.
How can I change project default settings?
I have more then 200 different objects(tables,stored procedures,functions,indexes etc.) and I don't want to change the settings of each object.
Anyone?
Thanks,
Eli

problem solved.
In my schema compare the options if "Ignore AnsiNulls" and
"Ignore QuatedIdentifiers" where checked,so updated AnsiNulls and QuatedIdentifiers settings was not marked as needs to be updated during the schema compare.
Also,I've set AnsiNulls and QuatedIdentifiers default settings
to true in database.sqlsettings file.
