Dapper and FBCommand

c# dapper firebird

Question

I have a question about how to write SQL's with Dapper.

Now I use something like this:

resultObject result;
String sqlCmd = String.Format("select * from SOME_PROCEDURE('{0}',{1},{2})", Param1, Param2, Param3);
result = FbConnection1.Query<resultObject>(sqlCmd, null).ToList();

But now I see that it is not so clean, And I found a FBCommand which allow me to use

FbCommand cmd = new FbCommand("select * from SOME_PROCEDURE(@param1, @param2)");
cmd.Parameters.Add("@param1", FbDbType.Integer).Value = value1;
cmd.Parameters.Add("@param2", FbDbType.Integer).Value = value2;

I don't know how to user Dapper with FBCommand, is it possible ? Or maybe using String.Format for building SQL is good way?

If there is a corresponding FbConnection, and if that connection is a standard ADO.NET implementation, and if it supports standard parameters, then yes, you could try doing:

using(FbConnection conn = ...)
{
    var data = conn.Query<SomeType>(
       "select * from SOME_PROCEDURE(@value1, @value2)",
       new { value1, value2 }).ToList();
    // ...
}

You could also try:

using(FbConnection conn = ...)
{
    var data = conn.Query<SomeType>("SOME_PROCEDURE",
       new { param1 = value1, param2 = value2 },
       commandType: CommandType.StoredProcedure).ToList();
    // ...
}
