Depending on whether you are trying to just add the two columns together, or add the sum of the columns together, you could either do:
select tbl1.column1 + tbl2.column as summation or
select sum(tbl.column1 + tbl2.column) as total

can any body tell me the query for this ,
Is this what you are looking for:
select tbl1.column1,tbl2.column2,tbl1.column1*tbl2.column2 as Result, sum(tb1.column1*tbl2.column2) as Total
This query will have the Total column as the same value for all the rows.

If having it in the same row is Ok, then my earlier query should work for you (providing of course that you specify the correct join condition).

Hi...
I'm trying to get programmatically a backup file of my database, here is the code:
<br />
string BakFilePath = System.IO.Path.GetTempFileName();<br />
<br />
SQLDMO.Backup bak = new SQLDMO.BackupClass();<br />
bak.Devices = bak.Files;<br />
bak.Files = "[" + BakFilePath + "]";<br />
bak.Database = "MyDB";<br />
bak.BackupSetDescription = "Something";<br />
<br />
bak.SQLBackup(srv);<br />
Under VS2005 c# SQL Server 2005, in debug mode there are no problem.
When installing on a win xp with SQL Express 2005, I have the following error:
<br />
[Microsoft][ODBC SQL Server Driver][SQL Server]Cannot open backup device 'C:\Documents and Settings\JOZ\Local Settings\Temp\tmp19.tmp'. Operating system error 5(Access denied).<br />
[Microsoft][ODBC SQL Server Driver][SQL Server]BACKUP DATABASE is terminating abnormally.<br />
I like sqldmo backup because is really quick... but this issue is driving me crazy... Can somebody help me please? 
Life is not short... the problem is only how you organize yourself

Maybe your SQL Server 2005 service is running under an account which has permissions to the backup folder, which the account used by SQL Express does not.
Try giving write permissions to the account under which SQL Express runs.

I have a program written in VC++6 that connects to a database through SQL-ADO. Occasionally the DB server will disconnect or reconnect or fail in some way. Right now I have no indicator when this happens on my program side, so users who are currently logged don't know about the error and when they try to save their work an SQL error comes up saying...
Error(0)80004005:Connection Failure
I'm looking for some kind of Disconnect or Reconnect event or indicator of some sort in SQL-ADO. SQL-DMO has the ConnectionBroken Event which seems to be about what I want. Is there anything similar in ADO? If not, what is the best way to detect a broken connection? I'd rather not resort to polling the server if possible.

If you're using System.Data.SQLClient.SQLConnection, you have a property called State (SqlConnection.State) which will return the current state of the connection.

Thanks. I can use the State property, but it isn't updating correctly. When the error occurs, state is still set to Open, even though the connection has been broken. Is there any kind of message or event that happens when there is a disconnect?

Get the data from one database table to anothter databse
select * from databasename.dbo.tablename

Assumes the DBs are on the same server (valid assumprion from the ?)
If the DBs are on different servers you will need to look into Linked servers (nasty things linked servers)

tran log of my database is now hge in size and my disc space is almost full.
what do i do now? should i take backup of tran log or change the path of transaction log file to another disc location..
please suggest..

I'm assuming you aren't backing up your transaction log at all. If that is the case then change the recovery model of your database to Simple. Then detach your database, delete the transaction log file and re-attach your database. A new log file will be created for you.
To set your recovery model to simple use:
ALTER DATABASE [databasename] SET RECOVERY SIMPLE
Do NOT do this while users are logged in. Wait for a time when there is no activity on your database. If you don't have a maintenance window which allows you to do this you will need to truncate your log and then shrink it.
To shrink your transaction log file, first get the logical name of your transaction log by running sp_helpdb 'your database name'. There will be 2 resultsets, the second one will have a column "name", for the row that refers to your log file, that is the logical name.
Then you can run the following script:
<br />
BACKUP LOG [Database Name] WITH TRUNCATE_ONLY<br />
GO<br />
<br />
DBCC SHRINKFILE([LOGICAL FILE NAME], [SIZE]) <br />
GO<br />
where [size] is an integer value in megabytes.
Again, this is only if you are not using your transaction log. The commands will be different if you need to backup your log file. Refer to BOL.

In answer to your question:

It's a good idea to keep the transaction log on a different disk to the database - doing this will speed up SQL Server.

I have a column in my table that is both telephone numbers and text. I have made the field type text as I want to be able to use both in my database. However when I import it into my database, it wants to import that field type as double?! so when it enters my database, all the text entries are null.
Please can someone tell me how to get both the numbers and the text in the database?

Create the table first in SQL
CREATE TABLE tblCust(RowId int IDENTITY(1,1) PRIMARY KEY, Phone nvarchar(20) NULL)
Then import and use column mapping.
