The very first thing we are going to do is to create a new Dto folder, and inside of it, a whole new CompanyForCreationDto class that we're going to use to the Put up ask for:
Develop an entity or design class of Consumer kind, this entity is going to be mapped to The shoppers table within the database.
We’ll show you tips on how to use dynamic parameters in the next illustration, where we’ll produce a new Enterprise entity in our databases.
Dynamic Parameters are especially great for advanced saved method, in case you require handle also a return benefit:
Execute – an extension strategy that we use to execute a command just one or numerous situations and return the volume of affected rows
Furthermore, for anyone who is Operating in an ecosystem where you're managing an current databases or a crew that handles the databases structure, Dapper may be ideal for you!
In this article, we produce a variable which contains a procedure name and also a dynamic parameter item with just one parameter within. Because our stored technique returns a worth, we use the QueryFirstOrDefaultAsync approach to execute it.
As soon as Dapper is enabled you can alter the Language drop all the way down to C# Software, map query success to C# courses, and use the .Dump() system to inspect the results:
So what is going to happen is, we define the interfaces for Repositories listed here, and put into practice these interfaces at another layer which is connected to Details access, in our case, Dapper.
In these tutorials, we provide a hands-on approach to the subject with phase-by-phase application illustrations that will help you in Understanding and putting the acquired expertise into exercise.
Pay attention that If the stored technique doesn’t return a value, You should utilize the ExecuteAsync technique for execution.
The ExecuteAsync system returns int Consequently, representing the quantity of afflicted rows in the database. So, if you need that data, You may use it by accepting the return benefit from this method.
If you need to simulate an mistake and take a look at that no rows might be established during the databases, you may toss an exception under the await code line. You'll discover no new rows in the Companies table.
Here, we make our query dapper tutorial for beginners and a dynamic parameters item (we are not working with an anonymous item anymore). We populate that item with our three parameters and afterwards get in touch with the ExecuteAsync method to execute our insert assertion.
When talking about these extension approaches, we must express that Dapper supports synchronous and asynchronous system executions. We’ll utilize the asynchronous Model of All those procedures.
