As you'll be able to see, after creating a new firm from the databases, we return a route to fetch our newly established entity.

Working with the update and delete is very very simple for the reason that we already have every one of the demanded know-how. So, Permit’s leap straight to your code.

The first thing we’ll do is create a new ASPNetCoreDapper database. Once the database generation, you could navigate to our resource code repository and find a script (First Script with Data.sql) you could execute to generate two tables and populate them with info:

Now, if we phone this method and pass an organization for creation to it, it is going to develop a new entity for us. But, though creating API’s Publish action, it is an effective apply to return a url, which the API’s end users can use to navigate to your made entity.

Every one of the aforementioned approaches supports parametric queries. Parameters are described in queries utilizing the “@” image and after that there are two approaches that could be utilized to assign values to described parameters: using nameless objects or the Dapper-particular DynamicParameter class.
