sql, query (*sigh*, I hate this filter)
I have an auto_increment key set up on my InnoDB table.
Whenever I delete all the records, the number isn't reset.
However, for my ISAM tables, whenever I delete all the
records, the auto_increment number is reset.
That's how ISAM tables work.
Is there a reason for this in InnoDB?
Yes: That's how InnoDB tables work. (So do MyISAM tables.)
The handler for each table type handles AUTO_INCREMENT columns
slightly differently. You're running across one of those differences.
Is there a way that I
can reset the auto_increment number when all the records
are deleted?
ALTER TABLE t AUTO_INCREMENT = 1;
I have a temporary table that has records
added and deleted all the time. I wouldn't want the record
number to eventually reach the ceiling for the datatype of
the field.
Any insight would be greatly appreciated.
Chris
