Description:
The commandbuilder does not handle SQL of the form.

select * from {database}.{table}

How to repeat:
Just execute the query in a data adapter, try using the commandbuilder to generate update statements and it will not generate the correct SQL (The database part will be silently dropped).

Suggested fix:
I have a patch ready that fixes it, just let me know where to fix it and I will. I am available at spam@henrik.org.

Ok, I found how to post files so I uploaded the files I modified (From the 1.0.4 release).

It seems that if you are connected to a 4.0.* database the MySqlField.DatabaseName doesn't get filled in with the correct data (It is null). So the fix I uploaded only works for 4.1 or greater.
