As you may see, there is nothing new with these two methods. We have a question and parameters, and we execute our statements While using the ExecuteAsync system.

I think that this process exists mostly for making easier to adopt Dapper in legacy codebases in which in lieu of dealing with strongly typed lists you've got to cope with a DataReader, and refactoring to implement a typed record it is impossible. If that’s the situation, then is the tactic for you. As the name suggest it just returns a IDataReader.

QueryFirstOrDefault – we use this technique to execute a query and map the primary final result or perhaps a default worth If your sequence consists of no aspects
