Deleted table file behavior!

[Eliezer Figueroa]

I just created a database and a table. I created 1 record in the table and query it. All worked just fine! Them I manually deleted the table .frm file and tried to do a select * on the table. To my surprise I still get to see the record. With the file deleted I created a new record and I got no errors! them I restarted the mysql service and restored the .frm

I query the table again and both record are there! the one created when the file was there and the one created while the .frm file was deleted. How is this posible?

I also noticed that I can copy a .frm file from one database to another and it will appear listed with a show tables but i get an error when I try to query it!
