Hello,
my problem:

I use a complex select statement. This statement works nice, but when
I ask for a speziell name to give me his data, then the select takes a
really long time like 5 minutes(there is only 345 datasets for that
name in the database). It worked in the future without problems.
I only can solve the Problem, when I make a backup from the database
and install it on other Server. What can cause the problem? Do you any
idea who the find the error?

Thanks
susi
