In this area, we're going to develop a straightforward repository sample. We’ll ensure it is very simple mainly because this article is about Dapper.
Here We are going to just determine the IUnitOfWork and inject it into the Controller’s constructor. Following that, we make independent Motion Procedures for each CRUD Procedure and use the unit of work item. That’s it to the implementation. Permit’s check it.
QueryMultiple – an extension process that executes various queries within the same command and maps final results
Dapper.Internet continue to provides important pros, especially in terms of efficiency and Regulate. Will take a look at Dappet.Web in upcoming content articles generating an easy CRUD application and searching at pros and CONS of it.
Execute – an extension strategy that we use to execute a command just one or multiple occasions and return the amount of impacted rows
QuerySingleOrDefault – executes a query and maps The end result or perhaps a default benefit In case the sequence is empty. It throws an exception when there is multiple factor within the sequence
Now it’s time to check our series of tutorials to cause you to understand Dapper and utilize it confidently with your .Web apps.
Within a former example, we used two SQL statements to return two effects then join them jointly in one item. But typically, for such queries, we don’t want to put in writing two SQL statements.

A couple of notes here. Considering the fact that we don’t have any business enterprise logic, we aren't creating a company layer to wrap our repository layer. For this sort of application, the service layer would simply call repository approaches and nothing at all more, incorporating an needless level of complexity to your write-up. Of course, we generally suggest utilizing the services layer in larger sized-scale programs.
Listen that In case your saved process doesn’t return a price, You should use the ExecuteAsync system for execution.
The ExecuteAsync approach returns int Therefore, symbolizing the amount of influenced rows during the databases. So, if you need that information, you can use it by accepting the return price from this method.
Do you think you're positive you need to hide this remark? It can develop into hidden inside your write-up, but will continue to be seen by way of the remark's permalink.
This process dapper tutorial for beginners executes a query that doesn’t return any resultset. Its return benefit incorporates that amount of rows influenced through the query. Should the executed essentially generates a resultset, that may be discarded.
Simplicity: Dapper supplies a simple and intuitive API for executing queries and mapping results. It helps you to publish SQL queries straight, supplying you with entire Manage over your database interactions.
