Okay - but your original post indicated that you wanted to write a web application in SQL.
ahmad mostafa wrote:

I'm assuming .NET code since you still haven't said the technology that will be linking to the SQL Server.
SqlConnection someConnection = new SqlConnection("connectionString");
SqlCommand someCommand = new SqlCommand("SQL Command Text", someConnection);
SqlDataReader reader = someCommand.ExecuteReader();
while(reader.Read())
{
}
Does this help? If not, then you need to elaborate on your question.

I don't know an upper limit but a system I'm working on is approaching a million new rows per day in just one of the tables - its been running for just under 2 years now.

Yes. But that is why you have indexes. 4000 rows per table per year is not going to cause too much of a problem anyway.

Do you mean "what size can be stored?".
If you read the SQL Server documentation[^] you will see that the maximum size is 2Gb.
Does this help?

Hi:
I think you may need to use the commandline option. By default the setup tries to create and install.
I remember seeing some commandline switch for /update and also an option for SAPWD to work with strong passwords etc.

Thank you very much for your comment. I also use the command line during the time that I install sql server 2k sp3a too. The command is: c:\sql2ksp3a\msde\setup.exe SAPWD=Admin DISABLENETWORKPROTOCOL=... I forget the command line but i already save it in a safe place. But I also use this method when I try to install sql server 2k sp4. But an error still occure, I will try to find the solution from the other source in order to install it.

I'm trying to add a fairly simple assembly to SQL server 2005; but keep getting a message:
6218 : Assembly 'EnableIrelandSystem' failed verification, run peverify on the assembly.
So - the only thing remotely controversial in th eassembly is a reference to System.Runtime.Interopservices (for <StructLayout()> ).
Any ideas?

I'm not sure what you mean.
Do you mean: How do I check if a table contains a primary key or not?
IF EXISTS(SELECT * FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS
WHERE TABLE_SCHEMA = 'dbo'
AND TABLE_NAME = 'Orders'
AND CONSTRAINT_TYPE = 'PRIMARY KEY')
BEGIN
-- The primary key exists
END
ELSE
BEGIN
-- The primary key does not exist
END

The database is just one layer of the application. What about the other layers? For instance, is it a web application or a windows forms application?
Most databases are designed to be multi user and you can have many connections open to them at the same time. MS Access and MSDE do impose limits however.

This error occurs while trying delete a column in SQL Server 2000. First I tried using CONSTRAINT statement, for deleting Indexes. But it seems to be an auto-increment column.
My general problem are two identical tables. While doing RDA Synchronization, two Rows are added to one of them, making it impossible to copy one into the other.

CREATE FUNCTION getamountdue (@customerid int)
RETURNS float AS
BEGIN
declare @x float
select @x=sum(totalamount-amountpaid)
from (installments inner join orders on installments.installmentid=orders.installmentid)
inner join customers on orders.customerid=customers.customerid
where customers. customerid=@customerid
return @x
END

Hi,
I'm new to programming and need some advice...
I have a windows application that I want to be running on several networked computers and accessing the same db (ms access file). I'm worried that there may be times when two user will access the db file at the same time and give an connection open error (when using ExecuteNonQuery). I've played around a little bit and have noticed that using the DataAdapter to Fill and Update does not give any connection open errors (even if the connection is open by mistake or if another Fill is happening).
So what's the best plan?
If I have a situation of multiple users of a db, should I try and use the DataAdapter as much as possible to avoid db status=open errors (and needing try/catch statement)?
Thanks for any advice you can give,
Ron

Does your database not handle multiple users ? What are you using ? SQL Server handles multiple users, and even MSDE handles up to 5 ( from memory ).

Hi Christian,
I'm using a MS Access 2000 database (I believe it's a Jet database?). SQL Server or MSDE might be too much for an end user with min. computer knowledge to install.

OK - Access is crap for this stuff. You basically have a problem, and the problem is that your technology is not up to the task.
You can easily deploy an app where the installer installs and sets up MSDE, I've done it myself with complete success.

Just to add to what Christian said. OleDbDataAdapter uses a OleDbCommand object internally to get the data from the database. There is no advantage, in terms of contentious resources (multiple opens), to using an OleDbDataAdapter over a OleDbCommand. The only advantage you get is that an OleDbDataAdapter will open a connection if it is shut already (by calling OleDbConnection.Open()) and will shut it afterwards, if it opened it. It is generally good practice, if you are using the Command objects to open the connection, run the query and close the connection again rather than just leave it open.

I have an ASP.NET application that needs to access a SQL Server. I was planning on using the MS Data Access Application Block (DAAB) but do not want to store SQL Server login credentials in config file as the DAAB seems to suggest. I want to collect the SQL Server account's username and password at runtime with a standard login webform.
Am I missing something, or does the DAAB not easily handle this? I am not using Windows Integrated security, I am using SQL Server security.
Has anyone been able to assign SQL Server login credentials to the DAAB at runtime as I was hoping to do?
I'd greatly appreciate any suggestions.
Thanks.

I'm using sql server 2000.
Is it possible to use a parameter passed to a stored procedure as the name of a table in a query? If I hardcode the table name into the query it works fine. But when I try changing the procedure to have the name passed, the syntax check fails with "Error 170: line 2: Incorrect synatax Near '@Tablename'."
[code]
CREATE PROCEDURE CreateTestTable2 @Tablename char(30) AS
CREATE TABLE @Tablename
(
TestID INT PRIMARY KEY NOT NULL,
TestInt INT,
TestString VARCHAR(10)
)
GO
[/code]
