First, what do you mean by "regs"?
If I understand your question, you want to know if mysql will re-use an old
auto_increment value that has been deleted. The answer is yes and no.
If you say: DELETE FROM mytable;
then the next insertion will cause the auto_increment value to begin at 1
If you say: DELETE FROM mytable WHERE myfield>0
then the next insertion will cause the auto_increment value to begin where
the auto_increment left off.

Hi everyone
My question is very simple, so i hope the answer will too :)
Well i have an index field in my table which is set as auto_increment. Well
question is, it's possible that mysql use values that have alredy been
deleted from older regs?
Thx in advance!
