Currently, I am facing a challenge of inserting a product into a SQL table. My approach involves using Kendo UI grid and AngularJS technologies. I am seeking guidance on how to properly validate whether the product already exists in the database before executing the insertion process. The database access is facilitated through a WebAPI method. Any assistance or suggestions would be greatly appreciated!
Thank you in advance!
One potential solution (which may not align with your specific needs) could involve implementing an Upsert method, typically utilizing the PUT verb. This method would check if the data already exists, and if not, create it. If it does exist, the method would update it accordingly.
However, if you prefer to use a POST method and receive an error for existing records, the standard response would be a 400 - bad request. The specific behavior may vary depending on the server-side framework being used. For example, in ASP.NET Web API, this scenario would likely trigger an invalid model state and return a BadRequest (400) response.
