Just before utilizing Dapper in our challenge, we have to prepare a databases and create a new Internet API project. So, Allow’s start with the database.
After the class development, we can register it as a singleton provider in the Startup course, Should you be applying .NET5:
As you are able to see, following developing a new company from the database, we return a route to fetch our recently made entity.
Dynamic Parameters are especially great for complex saved technique, just in case you will need cope with also a return worth:
Execute – an extension technique that we use to execute a command one particular or various times and return the amount of affected rows
As soon as we get several results Within the multi variable, we can extract both equally final results (company and workers per that organization) by utilizing the ReadSignleOrDefaultAsync and ReadAsync techniques. The main approach returns only one outcome, though the next returns a set.
Generally, we develop a See While using the exact name being an Motion approach, so let us produce an Index perspective and include the next code.
You've got entire Handle over how parameters are despatched to the databases, as you are able to see from what get executed:
So what is going to happen is, we determine the interfaces for Repositories here, and put into action these interfaces at A different layer that may be related to Info accessibility, within our scenario, Dapper.
Wanting to take your capabilities to another amount? Jump into our higher-affect classes in web advancement and software package architecture, all which has a concentrate on mastering the .
Lightweight: Dapper is a light-weight library with negligible dependencies. It doesn’t impose any complex configuration or set up, rendering it very easy to integrate into your tasks.
Transactions are pretty simple to use with Dapper. We can execute it utilizing the Dapper library (the one we already use) or maybe the Dappr.Transaction library, which is similar point as Dapper, just With all the extended IDbConnection interface. Inside our instance, we are going to utilize the Dapper library.
This method is sort of the same dapper tutorial for beginners as the former one particular, but with a person exception since we've been using the QuerySingleOrDefaultAsync strategy here and provide an anonymous item as the 2nd argument.
What is actually your practical experience with Dapper? Is it your goto Resource inside your initiatives or would you relatively use Entity Framework or another thing?
Simplicity at its Main: Dapper.NET concentrates on simplicity and ease of use. It won't try to summary away the databases, allowing you to put in writing and optimize your SQL queries specifically.
