It was believed that a woman with that kind of a hairline would outlive her husband as the V-shape reminded of the similarity of the veil that is worn during mourning. The Widow’s Peak refers to the downward V-shape that you see in a person’s hairline. I'm happy to research your questions and write some detailed explainations on more complex use-cases.Widow’s Peak is not a new name to men around the world but what many do not know is how the term came about.

If you run into problems, feel free to ask me on Twitter. If you're jumping into Dapper for the first time, take it easy! There are a lot of great examples in the GitHub repo for getting started. Check out their performance benchmarks Give it a try! It's one of the most frequented websites on the internet, and they do not play around when it comes to performance.ĭapper was created by their team in order to make mapping data to objects as painless as possible while being fast. Yes! And even better, it's built by the good folks over at StackOverflow. It's that critical to my project success. I also use Dapper in every single application I scaffold out. I'm not diving in deep here, but it seems like a great idea for future posts. There is a rabbit hole of use-cases where Dapper can be combined with other awesome libaries, like AutoMapper. Rob made a great point earlier, I'm not really diving in deep enough into mapping. I'm planning several follow up posts that cover scenarios around these topics, but I felt this article would become more reference than 'hey, this is a tool I like and you should check it out.'

Most database operations you need to make: SELECT, UPDATE, INSERT, DELETE are supported with a couple lines of code. But my goal here is to tell you what Dapper is meant to do. I don't need to worry about any of that work. I'm passing an anonymouse object for my parameters, and Dapper will assist with telling the database that I want to map to Kevin. The next parameter of QueryAsync (or many other Dapper methods) is a parameter object. Īnd if you wanted to get that data into an object that is actually useful. If you wanted to query that content, you could simply write the following SQL: SELECT Id, FirstName, LastName, EmailAddress, DateOfBirth FROM. Imagine you have a (relational) database table called Users. I'm not even going to show demo code, because I don't want you to write it.

This process is really tedious, and I've written my fair share of code that gets the string from ordinal position 0 and the long from ordinal position 52. There are a ton of ways to do this currently: Write your own mapping from a result set If you're using a relational database, such as SQL Server, MySql, or PostgreSQL, you probably have had to deal with the problem of 'how do I turn a result set into an object I can actually do work with?' Maybe it's better to start at the beginning. What is Dapper?ĭapper is a Micro-ORM or Micro Object Relational Mapper. NET with Dapper and this is an attempt to catch the eyes of developers who might have heard of object mapping from things like Entity Framework. My talk is entitled Better Object Mapping in. On the speaking circuit, I've been doing a good number of presentations on Dapper.
