Getting Dapper to return an empty string instead of a null string

Question

I know it\'s kind of the wrong thing to do, but I\'m dealing with a legacy codebase that has NULLS when it means empty strings and vice versa.

I can\'t immediately

Answer 1

You can control this with your queries, for example:

    public class Data
    {
        public string Foo { get; set; }
    }

    var result = conn.Query("select Foo = coalesce(Foo, '') from MyTable");

So in the above example, coalesce will return an empty string when Foo is null.
