Question

I’m working on a shopping cart and my problem is, how should I design database for size selection for products? Tshirts can be “XL, L, M, S” etc. and shoes can be “36,37,38,39…blabla” Should I do just one size table or many tables for several types (tshirt, shoes etc.)?

Thanks in advance…

Answer 1

Table: size_selection

Item_id numeric
Item_size varchar
Seq numeric

Item_id -> item table (say id = 1 -> tshirt. id = 2 -> shoes.)

So, your table would be

Item_ID   Item_size   Seq
__________________________
   1         S         1
   1         M         2
   1         L         3
   1         XL        4
   2         36        1
   2         37        2
   2         38        3
   2         39        4

Then, on the page, just get your dropdown values as

Select item_size from size_selection
where item_id = :p_ID
order by seq

Sequel syntax may vary in your flavour.
