Buiding Composite Columns | How to Guide
Stack different data elements within a column to return exactly the contents that you require
Using Composite Columns
The first place that you will probably see this in use is when we are combining a price or cost value with either a currency code or a currency symbol.
So here we are combining a variable from the store data (variants_price) with a static element (the USD currency code), and we have set to separate these two components with a space.
Another common use maybe to combine different elements together to meet a certain format requirement. It may be specified for a unique product id to be constructed from both product and variant level data.
This ID has the advantage of being unique to individual variants, but also ‘sortable’ into the product level groupings.
Your product name may need to consist of a certain combination of elements for some feeds. In the above example a wine merchant needs to pass their product name as a composite of Title + Vintage + Brand
There are lots of different possibilities of course, with Feed Donkey you have a very flexible builder to be able to cope with most if not every possible format requirement.
