controlled incrementing

Recommended Posts

I would like to know what you put into mysql to increment numbers, BUT only the ones that have a certain value like every entry with the value "2023" will have a number in seperate column that increments only for entries with this value. On another note, can mysql do the primary sorting and a secondary sort? For example: Sorting by values assigned to rows, and then sorting every row that has the same value by a seperate value.
If you don't understand what I'm asking I'd be glad to explain more thoroughly.

This is possible -- you simply have to make the AUTO_INCREMENT column part of a multiple-column index which includes both the column with the ID and the column with the "2023" in it. And yes, you can multiple fields in an ORDER BY clause.
