Hello group,
I have a function which is used to initiate sqlDataReader
object.
I was trying to invoke the close method on the DataReader object but
cant really do that as the function returns a datareader and cannot
access the datareader once the connection is closed.
Here is what I do:
public function getDataReader() as datareader

Hi, I feel a little dumb for asking this (considering im writing
TSQL) but there doesn't seem to be any definitive answers on the
search engines...
Okay I understand that if you open the ADO connection that you
close it with:
adoCon.Close
Set adoCon = Nothing

I am developing on a website that is utilizing SQL Server 2000. Shortly
after deploying the site, we began having timeout issues due to the max
connections.
1st instinct was to diligently tidy up our connections. We did so by
encapsulating with the using statement. Ex:
using (SqlConnection myConnection = new
SqlConnectionConfigurationSettings.AppSettings))

Hi,
Does SqlDataAdapter always close the connection (assuming connection was
closed before calling Fill()), even if an exception occurs while calling
Fill()?
Example:
try
{
myDataAdapter.Fill(myDataTable);

In my Finally block, I was using cn.close (where cn is an ADO.NET
connection object, SQLConnection to be exact) and then I came across the
following in some microsoft code.
If Not cn Is Nothing Then
CType(cn, IDisposable).Dispose()
End If
I have to admit, I'm not sure what happens here. Will someone explain this
line of code (the middle one, not the if statement LOL) to me please?

Hello,
I have a generic method in a utility class that grabs an sqldatareader
and returns it. Due to the fact that (AFAIK), you can't close the
database connection before you've read the data, this method doesn't
close it, it just returns the datareader. The calling code uses the
datareader and then just lets it drop out of scope, to be picked up by
the garbage collector.
Is this a problem? A friend of mine suggested to me that not...

Hi!
I am currently developing my first webapplication using .net (2.x)
In a couple examples seen in the helpfile that came with VS2008
i see that they are opening a connection to the sql server.
Issue a command or two, then close the connection.
My question is, wouldn't it be better to have One connection open during the
current session and when the session end, close the connection.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
