In this particular part, we're going to create a easy repository pattern. We’ll enable it to be simple simply because this informative article is about Dapper.

In this article we will just outline the IUnitOfWork and inject it in to the Controller’s constructor. Following that, we generate different Action Techniques for each CRUD Procedure and use the device of labor item. That’s it for that implementation. Allow’s test it.

The above code is quite simple to understand, right here We've got added a databases link string into a variable named myCS. Subsequent Now we have assigned a variable sql a database insert question.

Dapper is a lightweight, substantial-overall performance facts access Device crafted through the Stack Overflow staff. It provides a minimalist method of information accessibility layer in .

As explained from the subtitle, on this page I’ll deal with the basic principles of Dapper .Web, and all it's going to take to obtain informed about it are merely ten samples I've designed and posted on GitHub, listed here:

Because Dapper.Web doesn't abstract absent the database or provide computerized migrations, you'll need to deal with your database schema and manage schema improvements manually.

Here, we make a variable which contains a method identify and a dynamic parameter object with an individual parameter within. Since our stored procedure returns a worth, we make use of the dapper tutorial for beginners QueryFirstOrDefaultAsync approach to execute it.

You have got entire Handle over how parameters are despatched towards the databases, as you'll be able to see from what get executed:

As you may see, our query variable has two Decide on statements. The very first will return only one organization, and the 2nd a single will return all the workers of that company. Following that, we create a connection and afterwards use that relationship to get in touch with the QueryMultipleAsync process.

We’ll also produce a easy repository layer to wrap the logic up to stay away from applying Dapper queries immediately Within the controller.

Executes a query and maps the result to an index of dynamic objects or, if specified, to a list of strongly typed objects:

This solutions executes a query that return a resultset made of just 1 row and a person column. Just like the very good old IDBCommand.ExecuteScalar.

This process executes a query that doesn’t return any resultset. Its return price is made up of that quantity of rows affected via the question. In case the executed truly generates a resultset, which will be discarded.

Simplicity: Dapper supplies a simple and intuitive API for executing queries and mapping success. It helps you to publish SQL queries immediately, supplying you with whole Handle over your databases interactions.
