我试图报告有多少项处于特定状态。我得到的代码只返回有值的行，而不返回没有值的行

SELECT Department
       ,Status
       ,count(Department) AS "Number in status" 
       ,convert(VARCHAR, getdate(), 103) AS "Date report ran"
FROM [Server name].[xxx].[Database name]
WHERE STATUS NOT IN (
              'Closed'
              ,'Cancelled'
              )
       AND Department IN (
              'Department name'
              )
GROUP BY Department,Status

ORDER BY CASE 
              WHEN STATUS = 'Open'
                     THEN 1
              WHEN STATUS = 'In Progress'
                     THEN 2
              WHEN STATUS = 'Authorised'
                     THEN 3
              WHEN STATUS = 'Awaiting Auth'
                     THEN 4
              WHEN STATUS = 'Awaiting Collection'
                     THEN 5
              WHEN STATUS = 'Awaiting Delivery'
                     THEN 6
              WHEN STATUS = 'Awaiting Development'
                     THEN 7
              WHEN STATUS = 'Awaiting Engineer'
                     THEN 8
              WHEN STATUS = 'Awaiting Invoice/Credit'
                     THEN 9
              WHEN STATUS = 'Awaiting Quote'
                     THEN 10
              WHEN STATUS = 'Cancelled'
                     THEN 11
              WHEN STATUS = 'Chase End User'
                     THEN 12
              WHEN STATUS = 'Final Chase End User'
                     THEN 13
              WHEN STATUS = 'Closed'
                     THEN 14
              WHEN STATUS = 'Future Requirements'
                     THEN 15
              WHEN STATUS = 'In Test'
                     THEN 16
              WHEN STATUS = 'Next Release'
                     THEN 17
                     WHEN STATUS = 'On Hold'
                     THEN 18
                     WHEN STATUS = 'With End-User'
                     THEN 22
                     WHEN STATUS = 'With IIT'
                     THEN 23
                     WHEN STATUS = 'Processing Via Demand Management'
                     THEN 27
              END;

结果如下所示，但不包括所有其他可能为0的状态：

您需要一个状态表，至少包含状态描述和（可能）报告顺序：

CREATE TABLE Statuses (
    Status varchar(30) not null,
    ReportOrder int not null,
    ShowInReport bit not null,
    constraint PK_Statuses (Status)
)

现在，您可以使用

LEFT JOIN

将查询从该表写入另一个未命名表（因为您的查询当前声称查询的是数据库，而不是其

from

子句中的表：

SELECT Department
       ,s.Status
       ,count(Department) AS "Number in status" 
       ,convert(VARCHAR, getdate(), 103) AS "Date report ran"
FROM
    Statuses s
       left join
    unnamedTable t
       on
          s.Status = t.Status
WHERE s.ShowInReport = 1
       AND Department IN (
              'Department name'
              )
GROUP BY Department,s.Status
ORDER BY s.ReportOrder

如果您仍然希望在

行的输出中使用部门名称，那么最好也有一个

Departments

表，使用方式与上述非常类似：

...
FROM
    Statuses s
       cross join
    Departments d
       left join
    unnamedTable t
       on
          s.Status = t.Status and
          d.Department = t.Department
...

（您还应该在未命名表和状态之间有一个FK，以确保其中使用的所有状态值都有效）
