如何在SQL中垂直获取某些列

Question

我遇到了SQL语句问题。我想展示一些表中的一些数据;这是我的SQL图：

Database diagram

我想在表格中显示一些名为＆＃34; Signatures＆＃34;的信息， 我想在行中显示列：＆＃34; IdSupervisor，IdManager，IdSupervisor2，IdManager2＆＃34;） 在此信息下方，我想显示以下列：＆＃34; FirmaS1，FirmaG1，FirmaS2，FirmaG2）。

我在网上搜索没有成功。

这是我在两个不同的语句中实现的SQL查询， 但是我希望将两个查询合二为一。

查询1：

SELECT p1.Name as 'Supervisor', coalesce(p2.Name,'Unnecessary') as 'Manager', coalesce(p3.Name,'Unnecesary') as 'New Supervisor', coalesce(p4.Name,'Unnecesary') as 'New Manager' 
FROM Signatures s1
LEFT JOIN PersonalDepartment dp ON s1.IdSupervisor = dp.IdPersonalDepartment
LEFT JOIN Personal p1 ON dp.IdPersonal = p1.IdPersonal
LEFT JOIN PersonalDepartment dp2 ON s1.IdManager = dp2.IdPersonalDepartment
LEFT JOIN Personal p2 ON dp2.IdPersonal = p2.IdPersonal
LEFT JOIN PersonalDepartment dp3 ON s1.IdSupervisor2 = dp3.IdPersonalDepartment
LEFT JOIN Personal p3 ON dp3.IdPersonal = p3.IdPersonal
LEFT JOIN PersonalDepartment dp4 ON s1.IdManager2 = dp4.IdPersonalDepartment
LEFT JOIN Personal p4 ON dp4.IdPersonal = p4.IdPersonal WHERE IdRequest = 64;

查询2：

SELECT FirmaS1, FirmaG1, FirmaG1, FirmaG2 FROM Signatures WHERE IdRequest = 64;

结果：

Result of the two querys.
