Thanks ONeil

select top 1 from ... is one way. Select count(*) from is another - could be slow though if the re are a lot of records.

In sql server 2k i've actually seen Count(*) return a 1 when counting an empty table, had it happen several times, cant remember why it happened anymore.

Never seen it myself, must have been fixed in an early service pack - after all, count is one of the fundamental functions.

Are these folders located on the server, or are you selecting a folder in your local desktop? Have you checked whether you got write-permissions on the folder?

This folder is located on local desktop(or program files or documents and settings).I have no write permission on this folder. Whether there are any method to check the permission of the folder and change the permission of the folder using vb.net ?

In that case you'll need to backup on the server, and copy the backup from the server-machine to your local machine. Can you make a backup to the root of C: on the servermachine?

You'll need permission. Ask your network-administrator if you can't change the permissions.
Hope this helps,

In that case, you should be able to backup to C:\.. Have you tried whether you can backup there? It's important because it rules out any other problems, like a full harddisk and the likes.

You can't "grant" yourself permissions from code that easily, that would be a security-hole. If you can't copy a text-file to the appropriate folder, then you also can't backup there. Can you check whether you can write a textfile to the folder that you want to backup to?
There should be a local administrator-account on the machine. That's the one that's used to set/check the permissions.

Sounds like you do have write-permissions then 
It might be that the path is too long, or the spaces in the path might cause problems. Can you backup to "C:\PROGRA~1"?

No. i can not backup to this path. Also not on desktop and documents and settings folder. Except these folder i can take backup in any folder programmatically.

Hi all,
i am doing this through vb code. After importing the data ill be moving this data in an excel sheet.
I need to know which would be the best and easy way:
1. using SSIS/DTS package.
2. using a stored procedure(Bulk insert statement).
At a time i have to move data from 2 csv into database.
Can anyone please let me know thw pros and cons of the approaches?
Thanks & Regards,
Preet

I have done this before by reading the csv file and creating a xml file from the csv file. and then pass the xml as a string (varchar) to the stored procedure. within the stored procedure you should be able to convert the string to xml and then that will act like another table.

Hello,
I have some problem with search a skills like c, c#, etc. by using Containstable .
My host provider does not change noise words. Due to this we are using below quarries
If users searching a keyword like C, then query is as follows…
select id,skills,[state],metroarea,designation,cname,jobtype,city,rank FROM peoplesurge_posting as posting INNER JOIN
containstABLE(peoplesurge_posting,(skills,[state],metroarea,designation,cname,jobtype,city),'ISABOUT ("c*")') as frees ON frees.[key]= posting.[id]
Note: 'ISABOUT (C)' for this it takes as a noice word then no rusults were displayed. Due to this we adding * to keyword c. this querry gives some results but it gives wrong results i.e starting character of C
Like c, c++, c#......etc
Please resolve this problem ASAP. It’s very urgent for me.
Thanks,
Satish.

Hi Everyone.
I have a relative simple question. I want to load an image into a SQL 2005 Database, but I dont want to write a program to do this. Is there any way that I will be able to upload the image into SQL without a Windows/Web application? Purely in SQL itself?
Your help will be greatly appreciated. I know it's properly a simple question, but I am looking for a shortcut 
Kind Regards,
Elizma

Have a look at UPDATE[^] statement's WRITE method if you have varbinary column. Otherwise see WRITETEXT[^].
The need to optimize rises from a bad design.
