Hi,
I'm using a .mdf (&.ldf) sql DB file in my ASP.NET application (it's in \APP_DATA), and I can see in the connection string that it is connected via SQLEXPRESS.
I know I can take the same .mdf file and attach it to MSSQL server and work with the same file under a MSSQL connection.
My question general is: After migrating a DB file from SQLEXPRESS to MSSQL will my DB work as a regular MSSQL DB or it will still have the SQLEXPRESS limitaions?
Thanks
Rafael.

The limitations will most likely be in the software, not the file.

So if I use the same mdf file via MSSQL I will Not get any SQLEXPRESS Limitations?

I Have a MS SQL Store proc, which takes max value of a field from the table for a day ( That field has got date part )and adds 1 if it exists or creates new if it does not exists.
Logic is like this
select a = max ( ID) where ID like (20070321%) /*Denotes March 21 2007*/
if (a is null ) set 200703210001
else a = a+1
insert into table (ID,....) values (a,....)
I am getting primary key violation error occassionaly.
I would like to know, How the SQL Server handles concurrent request for executing storedprocedures.
For example if it is sequential my logic should work fine
else
There can be duplicate values for ID fields.
Please help.

If this is in SQL Server 2005, you can wrap it inside a TRY/CATCH block.

Hi,
Thanks for the reply.
It is SQL 2000 / 7.0
Any other optimal solution

Well, you could always try something like this:
insert into table1(...)
select @id, @col2, @col3
from table1 where not exists (select id from table1 where id = @id)

Hi,
Personally, in this case I'd use an Identity column for the primary key, and put the date information in another column defaulted to get the date (DEFAULT GETDATE()). I'm not sure what having the date as part of the primary key is buying you.

Replace ' with ''
str.replace("'","''");

Be very careful with his solution at it can hide security problems. It you want to reduce the risk of your database being attacked then I suggest you don't use that solution.

Use parameterised queries.
For example:
INSERT INTO MyTable(Column1, Column2) VALUES(@value1, @value2);
cmd.Parameters.Add("@value1", someValue)
cmd.Parameters.Add("@value2", someOtherValue)
cmd.ExecuteNonQuery()

is the Select Top functionality or an alternative available in sql server 2000?
if I have this data...
100
200
330
445
665
887
999
...I know I can achieve it by ordering it and then using the if value > ALL ... but what if it is a lot more complicated than this?
thanks
Visual Studio can't evaluate this, can you?
public object moo<br />
{<br />
__get { return moo; }<br />
__set { moo = value; }<br />
}

Yes.

Which is it?
SELECT TOP didn't exist before 2005, did it..?

Yes, it did. TOP was introduced in SQL Server 2000

I found my problem, it seems that Select TOP has changed it's capabilities a lot in 2005, and this was the issue. Thanks.
On a sidenote, I'm sorry for the poor quality of some of my posts, but I'm really just trying to learn and help people at the same time. Thank you for remaining professional and not just breaking down all of my ideas because you think I'm an idiot.
