How can you create a personalized sorting order using odata?

Within my AngularApp, I retrieve data from a WebAPI using OData queries.

All the retrieved results contain both a date and an integer status code. The status codes range from 1 to 4.

I am aiming to organize my results in such a way that all items with a status code of 1 appear at the top of the list. Following this, items with statuses 2, 3, and 4 should be sorted based on their respective dates rather than their status codes.

Is this achievable?

At present, my code is structured as shown below; it only arranges the data by date without considering the status codes:

return Products.query({ $orderby: 'Date' });

Answer №1

Based on the information provided, it seems like you are looking to have all Products with a StatusCode of 1 treated equally without any further sorting by Date. However, if you are open to allowing all Products to be sorted by both StatusCode and Date, there is a simple solution available:

return Products.query({ $orderby: 'StatusCode,Date' });

The $orderby query option in OData v4 involves "a comma-separated list of expressions used to sort the items based on their primitive result values". Typically, property names are utilized as expressions to generate sort values.

If you wish to reverse the ordering for a specific property, simply add the desc suffix to that property as shown below:

return Products.query({ $orderby: 'StatusCode,Date desc' });
