Question

I have a MySQL table with 2 fields:

pd_code and pd_sort (pd_sort default value=0). For each product it is possible to specify an order index (in pd_sort) -1000, -900 and so on.

So when I print out products in PHP, i would like to sort them out like this.

product1 (pd_sort = -100), product2 (pd_sort = -90) etc, and then the rest products (where pd_sort = 0) sorted by pd_code.

ORDER BY pd_sort,pd_code works only for 2 products.

Any suggestions?

If I understand right, you should try something like this:

SELECT * FROM table
WHERE pd_sort <> 0
ORDER BY pd_sort

UNION

SELECT * FROM table
WHERE pd_sort = 0
ORDER BY pd_code
