I don't understand your question
Do you want to store the back up of your SQL Server database somewhere?
Do you want to store the back up of something else in SQL Server?

It depends on the situation.
I generally put the connection string in the config file - And I use a trusted connection, so the user name and password are not exposed.

Could you give me a sample by any chance ?

Of what? Putting a connection string in the application's configuration file? That is a very basic thing and is covered in any basic introduction to the .NET Framework.

SELECT T2.col1, T1.Col2, T2.Col3
FROM T1
RIGHT OUTER JOIN T2 ON T1.Col1 = T2.Col1

I appreciate ur help. But sorry Colin Angus Mackay it doesnt give the format i wanted,I already tried out all the joins.

Hi Raj,
select
t2.col1,
t1.col2,
t2.col3
from
tab2 t2
LEFT OUTER JOIN tab1 t1
ON ( t1.col2 = ascii(t2.col3) - 96 )
Results:
col1 col2 col3
----------- ----------- ----
1 1 a
1 2 b
1 NULL c
1 NULL d
Pretty silly way to join data though, I hope it was part of a "puzzle" question and not a serious solution.

In that stored procedure remove '' around @BDate.
i.e., datediff(Month,'dbo.Table.Column',@BDate)

It is most advantageous if you want to get data in or out of the database because it is the only way to do that.

Dear Ranga,
we cant talk about advantages of ADO.NET because either u use c# or VB or any language that is supported by .net framework the only way to connect to the backend database is by using ADO.NET technology. But we can have a debate on connected scenario and un-connected scenario in ADO.NET or else we can talk about pros and cons of data controls provided in ADO.NET.

ADO works on connected environment whereas ADO.NET(Adapter) will be able to work in disconnected environment.

Hey gurus,
I have 2 threads, both of them are calling a method which is connecting to database and reading data.
Here is the thread function.
Everything is okay first thread. But, while calling SqlConnection.Open() from 2nd thread, I am getting exception.
Exception is "Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached."
But, by default pooling is true with maximum 100 connection. Here I created only one connection from 1st thread. Could you please help me....
Here is my thread fucntion...
<br />
private void StartLoading()<br />
<br />
{<br />
<br />
SqlCommand sqlCommand = null;<br />
<br />
SqlDataReader sqlDataReader = null;<br />
<br />
try<br />
<br />
{<br />
<br />
sqlCommand = new SqlCommand();<br />
<br />
sqlCommand.Connection = new SqlConnection("Data Source=XXX;Initial Catalog=XXXXX;Integrated Security=True");<br />
<br />
sqlCommand.CommandText = " SELECT * FROM table";<br />
<br />
sqlCommand.CommandTimeout = 0;<br />
<br />
sqlCommand.Connection.Open();<br />
<br />
sqlDataReader = sqlCommand.ExecuteReader();<br />
<br />
while (sqlDataReader.Read())<br />
<br />
{<br />
<br />
<br />
}<br />
<br />
}<br />
<br />
catch (Exception ex)<br />
<br />
{<br />
<br />
}<br />
<br />
finally<br />
<br />
{<br />
<br />
if (null != sqlDataReader && !sqlDataReader.IsClosed)<br />
<br />
{<br />
<br />
sqlDataReader.Close();<br />
<br />
}<br />
<br />
if (null != sqlCommand && sqlCommand.Connection.State != ConnectionState.Closed)<br />
<br />
{<br />
<br />
sqlCommand.Connection.Close();<br />
<br />
}<br />
<br />
}<br />
<br />
}<br />
