SQL查询结果自定义排序

一般情况之下，我们可以使用ORDER BY ...ASC或DESC来做查询排序。如：

SELECT * FROM [dbo].[SalesPerformance]
ORDER BY [Salesman] ASC

GO

Source Code

如果需要求某一些值先排在前面，其余的数据再按规则排序，如Salesman的值‘S0008’，‘S0032’，‘S0022’排在前3位：

SELECT * FROM [dbo].[SalesPerformance]
ORDER BY CASE
    WHEN [Salesman] = 'S0008' THEN ''
    WHEN [Salesman] = 'S0032' THEN ''
    WHEN [Salesman] = 'S0022' THEN ''
    ELSE [Salesman] END ASC
