ExecuteNonQuery error

[TerceiraSoft]

I am Trying to execute this

SessionAuto.ExecuteNonQuery("UPDATE LinhasPedidosPOS SET Quantidade = @qt WHERE ID = @id", new { Qt = qtd, linha.ID });

ID is a Guid Value

I get this error
Must declare the scalar variable "@qt".

if i use RepoDb to execute the same thing it works fine.

using SqlConnection db = AppHelper.CriarDbConnection;
db.ExecuteNonQuery("UPDATE LinhasPedidosPOS SET Quantidade = @qt WHERE ID = @id", new { Qt = qtd, linha.ID });

What can be the problem with this?

Thanks.

I think i found the solution

session.GetDirectDbConnector().DbConnection.ExecuteNonQuery("UPDATE LinhasPedidosPOS SET Preco = @preco WHERE ID = @id", new { Preco = preco, linha.ID });
