Just before using Dapper inside our undertaking, we must put together a database and develop a new Net API project. So, Permit’s start with the databases.

Effectiveness: Dapper is incredibly fast and effective. It minimizes the overhead of mapping benefits to objects, leading to substantial-effectiveness databases entry. ️

QueryMultiple – an extension approach that executes many queries throughout the exact same command and maps benefits

As soon as Dapper package is installed, we are ready to perform databases functions within our .NET app. In the down below code we've been inserting a report into a database table with Dapper.

1 critical Take note: If you like the write-up thus far, then maybe it might help more that you should know that we updated our Net API High quality version with A different reward book known as ASP.

QuerySingleOrDefault – executes a query and maps The end result or maybe a default value When the sequence is vacant. It throws an exception if there is multiple factor in the sequence

Normally, we create a Look at Using the similar name as an Motion method, so let's build an Index check out and increase the following code.

You've got whole Management in excess of how parameters are sent towards the databases, as you could see from what get executed:

So what's going to materialize is, we define the interfaces for Repositories right here, and employ these interfaces at A further layer that is connected with Knowledge entry, inside our scenario, Dapper.

In these tutorials, we offer a palms-on method of the topic with move-by-move program examples which will aid you in Finding out and Placing the acquired expertise into exercise.

Now you've got a totally practical API which can interact with a SQL Server database applying Dapper. You understand how to fetch knowledge within the database, increase new records, update existing types, and delete documents you no longer want.

Following up, you’ll see how to ascertain a link to your SQL Server employing dapper tutorial for beginners a relationship string in the appsettings.json. From there, we’ll write the code that interacts with our database, sending queries by means of Dapper to execute the CRUD functions.

This procedures executes a query that return a resultset product of specifically one row and just one column. Just like the fantastic old IDBCommand.ExecuteScalar.

This technique executes a question that doesn’t return any resultset. Its return worth includes that quantity of rows affected via the question. In the event the executed truly generates a resultset, which will be discarded.

Simplicity: Dapper gives a simple and intuitive API for executing queries and mapping effects. It lets you compose SQL queries directly, supplying you with total Manage around your database interactions.
