Also, for the id of the last record inserted, if you're using MySQLi, it would look like this:

$mysqli->insert_id

If there are no inserts being done on a table, then SELECT MAX(ID) should be fine. However, every database has a built-in function to return the most recently created primary key of a table after an insert has been performed. If that's what you're after, don't use MAX().

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

IF you've just inserted into a table with auto_increment you can run right after your query.

SELECT last_insert_id();

Otherwise the max(id) FROM table

SELECT id FROM table ORDER BY id DESC LIMIT 1 should work as well

If you mean the latest generated ID from an insert statement with an auto-increment column, then mysql_insert_id() should help ya out
