How to get latest ID number in a table?

Question

How can I get the latest ID in a table?

Answer 1

If the table has an auto_increment column defined - you can check by looking for "auto_increment" in the output from DESC your_table, use:

mysql_insert_id

Otherwise, you have these options:

SELECT MAX(id) FROM your_table
SELECT id FROM your_table ORDER BY id LIMIT 1
