Thanks for your reply...
I have two SQL DB servers.
On my test server I connect using SA and issue a simple command such as "select top 10 post_count from users order by post_count desc". It correctly retrieves the information and shows in the chart.
In my production server I try to connect with a username/password (which contains "+"). If I connect with SA it shows the database, if I connect with [username] it doesn't show anything. Note that this [username] is the owner of my main database. If I try to simply enter the database name it won't allow me to click "NEXT".
If I use SA on my production server I can see the list of databases, which I can use to select the one I need. And now that I think of it, I can issue the query ""select top 10 post_count from users order by post_count desc" but I have to add the owner to the table name as in [username].[table]... So this is sorted, but...
I don't want to use SA!
I will probablt have to check permissions on my database... Interesting that [username] is the owner, but the database is not listed when logged in with that user.
