我有如下Manufacturer實體： class Manufacturer
{
[Key]
public int Id { get; set; }
[DisplayName("Manufacturer Code")]
public int Code { get; set; }
[DisplayName("Manufacturer Name"
是否可以使用來自WHERE子句的別名from avg(n.nota) as media？ SELECT a.nome AS nome, c.nome AS curso, avg(n.nota) AS media from Aluno a
JOIN Matricula m ON m.aluno_id = a.id
JOIN Curso c ON m.curso_id = c.id
JOIN S
在個人項目中，我有這樣的事情： template <typename T>
