Have you tried to work through the problem or are you just asking someone to do it for you?

Hi,
Quick guess would be that you have a pending transaction which needs to be committed.
Perhaps the easiest way to see this is to run the code to any point where you think the data would be persisted and then see from SQL Server Management Studio if you have locks on the data. If you have locks (specifically X-locks), the transaction is active.
Hope this helps,
Mika

Hi,
I guess you are connecting to named instance. Check:
- connection string, especially check server name and instance name. (also keep in mind that in c# \ is an escape sequence unless you have @-character before string: "\\\\server\\instance" == @"\\server\instance")
- check that SQL Browser process is running on server
This error can also occur simply because your network doesn't allow communication to the server for example because of a firewall.
Hope this helps,
Mika

Hi,
I'm trying a stored procedure(in SQL server 2000) which retrieves a table of information that contains text fields. But I couldn't reach as I'm getting struck with an error being thrown as "Implicit conversion from data type text to nvarchar is not allowed. Use the CONVERT function to run this query." Could some one assist me in sorting this out.
The error is in the following line
DECLARE @Olddescription nvarchar(4000)
SELECT @Olddescription = description from @ProblemsTable where rownum = 1
Notes:
@ProblemsTable is a local table being created with the following line of codes
Declare @ProblemsTable table
(
rownum int IDENTITY (1, 1) Primary key NOT NULL,
description text
)
insert into @ProblemsTable SELECT description FROM problems WHERE id = @IncidentID
Thanks in advance,
Kathir

Obvious isn't it?
SELECT @Olddescription = CONVERT(NVARCHAR(4000), description) from @ProblemsTable where rownum = 1

I was attending interview recently and was asked a question on SQL. Why should we avoid using cursors inside store procedure. I really didnt know until they asked that question. Can anyone please describe in few lines giving various reasons why we should avoid using cursors inside store procedure.
Thanks
Mark.

Poor performance. One of the main strengths of a database is performing set based queries/updates. A cursor makes it row based. There are times when it is unaoidable, but whenever possible avoid them

hi all,
i use following procedure for backup of a database
Private Sub BackupDatabaseUsinSMO(ByVal DatabaseName As String, ByVal UserName As String, ByVal Password As String, ByVal ServerName As String, ByVal DestinationPath As String)<br />
<br />
Dim conn As ServerConnection = New ServerConnection(ServerName, UserName, Password)<br />
Dim myServer As Server = New Server(conn)<br />
<br />
Dim backup As Backup = New Backup<br />
backup.Action = BackupActionType.Database<br />
backup.Database = DatabaseName<br />
DestinationPath = System.IO.Path.Combine(DestinationPath, DatabaseName + ".bak")<br />
backup.Devices.Add(New BackupDeviceItem(DestinationPath, DeviceType.File))<br />
backup.Initialize = True<br />
backup.Checksum = True<br />
backup.ContinueAfterError = True<br />
backup.Incremental = False<br />
backup.LogTruncation = BackupTruncateLogType.Truncate<br />
backup.SqlBackup(myServer)<br />
<br />
<br />
End Sub
above code works well on XP OS but when i run this code on VISTA machine then it give error "Backup failed for Server 'Machine\Instance'." Inner Exception is {"An exception occurred while executing a Transact-SQL statement or batch."}
anybody have idea that how can i perform BackUp and Restore operation on VISTA .I use SQL Server 2005 Express edition

It makes no difference for SQL SMO whether it's XP or Vista. I'd hazard a guess that in the server with Vista, SQL Server does not have enough permission to write into the backup folder.
But as I said, this is just a guess.

above code works fine on both OS (XP and VISTA)

hi all...this may sound dum but i need the help...how can i convert this value "86400000" from milliseconds into hours
living life on the flip side
|
|
|
|
|
There are 1000 milliseconds in an second
There are 60 seconds in a minute
There are 60 minutes in an hour
1000 * 60 * 60 = 3600000 milliseconds in an hour.
I'm sure you can figure out the rest of the maths.
