## CommonAdjust Examples

Most examples below use an outboard database table named pricing, but any valid table including the products table can be used. We will refer to this pricing table:

      code    common  q1     q5     q10    XL    S      red
      99-102          10     9      8      1     -0.50  0.75
      00-343                               2
      red      0.75

The simplest case is a straight lookup on an attribute; size in this case.

      10.00, ==size:pricing

With this value in the price field, a base price of 10.00 will be adjusted with the value of the size attribute. If size for the item 99-102 is set to `XL` then 1.00 will be added for a total price of 11.00; if it is `S` then .50 will be subtracted for a total price of 9.50; for any other value of size no further adjustment would be made. 00-343 would be adjusted up 2.00 only for XL.

      10.00, ==size:pricing, ==color:pricing

This is the same as above, except both size and color are adjusted for. A color value of red for item code 99-102 would add 0.75 to the price. For 00-343 it would have no effect.

      10.00, ==size:pricing, ==color:pricing:common

Here price is set based on a common column, keyed by the value of the color attribute. Any item with a color value of red would have 0.75 added to the base price.

      pricing:q1,q5,q10:, ;10.00, ==size:pricing, ==color:pricing:common

Here is a quantity price lookup, with a fallback price setting. If there is a valid price found at the quantity of 1, 5, or 10, depending on item quantity, then it will be used. The fallback of 10.00 only applies if no non-zero/non-blank price was found at the quantity lookup. In either case, size/color adjustment is applied.

      pricing:q1,q5,q10:, ;10.00 ==size:pricing, ==color:pricing:common

Removing the comma from the end of the fallback string stops color/size lookup if it reaches that point. If a quantity price was found, then size and color are chained.

      pricing:q1,q5,q10:, ;products:list_price, ==size:pricing, ==color:pricing

The value of the database column `list_price` is used as a fallback instead of the fixed 10.00 value. The above value might be a nice one to use as the default for a typical retail catalog that has items with colors and sizes.
