It is alreday the second day , which I spent in fighting with database. The task is quite trivial, and it is absolutely obscure why it is working so slow? Actually I made right solution time of ACESS has gone. I am not sure that I have to use MySDQL, but it is absolutely clear, that ACCESS should be killed. May be, I'll decide to use SQL Srerver in the future, but it costs prety much. I am not sure that I need to invest money right now.
Anyway, the task is the following. I have to remove all records with the keyword ALMAGEST. That is why I should remove all personal records from tha table "People" and keyword records for every person, who has a keyword ALMAGEST. Now I see some kind of success... How to test it? There are about 8000 personal and 17000 keywords records...
