Question

我有很多表但是例如让我们考虑2个表，即Employees和FileEntries。我从两个表EmployeeID,FileStatus,FileName,EmployeeName中选择这些字段。这两个表都有1个公共字段，即EmployeeID。即使FileEntries不在Employees表中，它也可以存在EmployeeID。所以我想从两个表中选择所有记录，但如果它不在Employees表中，则新字段应显示'NotRegistered'。

@EmployeeID int

 INSERT INTO @Branches 
 SELECT BranchID From vw_OrganizationTree WHERE OrganizationID = @OfficeID  --inserts 3 always because we got only 1 organization i.e. 3

  Declare @IsRegistered varchar(20)= 'Registered'     

  If ((Select count(*) from RegisteredEmployees where EmployeeUniqueID= @EmployeeUniqueID) <1)

Answer 1

当RE.EmployeeUniqueID为空时使用案例然后＆＃39; Not Yet＆＃39;其他＆＃39;注册＆＃39;在最终的选择查询

中结束

为什么我的查询没有显示正确的结果？
