Hi Guys,
I have sql "

C++

SELECT loc.street_1 + ', ' + ISNULL(loc.street_2, ' ') AS street

Now I just want to wipe of "," after first street name when second street name is Null. I tried like ISNULL(loc.street_2, '\b') but it's not working.. even replaced \b with 08(ASCII code) still didn't got what I want.. can one have any idea how to do that..

Thanks a lot...

There's no backspaces going to work like that in SQL, you need to use the string functions inside TSQL to build the substring you're after. Using a backspace to try to delete a character wouldn't even work in C#, I don't think. It's just a bad idea.
