It's not moot: Dapper doesn't auto-generate the query for you, it's just a thin layer over .NET's SqlClient to reduce boilerplate of converting to and from C# objects. You still have to write your SQL statements, and in your example you'd still be able to refer to your array by name: select SomethingID where AnotherThing in @yourNamedArrayParameter More here: https://github.com/StackExchange/Dapper#list-support If you're not using Dapper just use a user-defined table type to hold your data and join on it instead of using WHERE IN.

I'm actually a big fan of myBatis [0] for this very reason. You still write all the SQL, including stored procedures. All it does is map objects to input parameters, and map result sets to objects. Which is awesome, because that's the part of database processing that is actually tedious and sucks. Writing SQL is not. I think StackExchange's Dapper [1] works similarly in the .NET world.
