Dynamic Parameters are In particular great for intricate saved course of action, just in case you have to have cope with also a return price:
The very first thing we’ll do is produce a new ASPNetCoreDapper database. After the databases development, it is possible to navigate to our supply code repository and find a script (Initial Script with Details.sql) you could execute to develop two tables and populate them with data:
Now, if we get in touch with this process and move a corporation for generation to it, it'll produce a new entity for us. But, even though developing API’s Write-up motion, it is a superb practice to return a link, which the API’s consumers can use to navigate for the designed entity.
As you can see, there is nothing new with these two strategies. We now have a question and parameters, and we execute our statements While using the ExecuteAsync process.
I feel that this process exists predominantly for creating simpler to adopt Dapper in legacy codebases the place in lieu of coping with strongly typed lists you might have to manage a DataReader, and refactoring to employ a typed record it is not possible. If that’s the situation, then is the tactic for you. As the name recommend it just returns a IDataReader.
QueryFirstOrDefault – we use this method to execute a query and map the 1st result or maybe a default benefit When the sequence is made up of no elements
