Getting last value and increasing it by one

Hello,
My name is Tim and I am new here so i would just like to start of with saying hi to everyone!

the problem i have is i am using asp.net and SQL and I want to get the last value of the called vidid and increase it by one.

I have found this code
SELECT MAX(vidid) + 1
FROM dbo.Videos

I am using dreamweaver 8 and I use the test button and it submits it and comes up with the value i want.

I then press ok and go to bindings to get the value and there are no binding so i wrote the code in my self and it does not display anything not even a error msg.

I have also tryed this code

SELECT vidid + 1
FROM dbo.Videos
ORDER BY vidid DESC

This does not work aswell but if i remove the + 1 then i see that last value.

Any ideas ?? like alternate code

Thanks

Tim

Hi Tim,

I'm not familiar with dreamweaver but your original SQL query should work. If it returns a value in query analyser then make sure you're binding it correctly and also check your database connection string in .net.|||

i used a sqlcommand instead and its working now but thanks anyway.|||hi
if you use this value for inserting new record in a multi user application your solution may not work.check it.
