mysql UPDATE ordini SET prezzo = prezzo/1.024, totale = totale/1.024

You are selecting data for numordine = 1157, but are updating all records
that have
numordine 1385. 1157 1385.
Try to use 'concat()' function.

Subject: dropping multiple tables with one command
But you can do DROP table1; DROP table2; DROP table3; etc..
You can do even better:
drop table table1, table2, table3;

Hi,
since MySQL stores stored procs in mysql db you need to make backup of
