Dear List -

Thanks for all your help.

How do I reset auto_increment so that the primary key will start from
1. The primary key is now 2421. I have deleted all the data in the
table and started over, and the primary key just increments from its
previous value. Setting auto_increment=0 does not work for me, why I
don't know.

Help and advice, please.

Thanks in advance.

UPDATE tablename AUTO_INCREMENT=3D1;

======
Daniel -

Thanks.

This is what I get -

mysql> update Visit3 auto_increment=1;
ERROR 1064 (42000): You have an error in your SQL syntax; check the
manual that corresponds to your MySQL server version for the right
syntax to use near '=1' at line 1

Same error if auto_increment is in caps.

What did I do wrong?

Thanks in advance.

Use 'ALTER tablename AUTO_INCREMENT=1' rather than 'UPDATE tablename
AUTO_INCREMENT=1'.

Sorry, you didn't --- I did. I was working on something for
myself simultaneously and somehow crossed wires. My apologies.

That's not an UPDATE query, it's an ALTER TABLE query.

ALTER TABLE Visit3 AUTO_INCREMENT=3D1;

Again, my apologies.

Yeah, again, my fault. Not enough coffee on this cold (~7F)
winter's day, perhaps.
