Easy enough. Get the numeric part via CONVERT, then get the rest of the string from the length of the numeric part, plus one:
SELECT tag, @num := CONVERT(tag, SIGNED) AS num_part, SUBSTRING(tag, LENGTH(@num) + 1) AS rest_of_string from tags; +--------+----------+----------------+ | tag | num_part | rest_of_string | +--------+----------+----------------+ | 1foo | 1 | foo | | 23bar | 23 | bar | | 234baz | 234 | baz | +--------+----------+----------------+ 3 rows in set (0.00 sec)
