The value would be an integer, not a string but that shouldn't cause a
problem. To quote the docs:
ALTER TABLE t2 AUTO_INCREMENT = value;
You cannot reset the counter to a value less than or equal to any that have
already been used. For MyISAM, if the value is less than or equal to the
maximum value currently in the AUTO_INCREMENT column, the value is reset to
the current maximum plus one.
It probably should be said that there is normally no reason to play with
auto-increment values.
