Hi
I 've done some indexes in my tables and I solved my problem.
But I still confused with indexes. I created one multiple index with the
main 4 columns for mensagenspara 's table. But it doesn 't workSo I stand corrected )
Sorry for the mis-information. Thanks Mark!!

I have a problem. When I try to select some names starting with extra
alphabets (? ? ? ? etc) I simply don 't get required results i.e.
if I give a select command like
select * from etry
uname -a
to see if your OS is 64bit or not.
