如何重新排序SQL查询？

Question

我正在为SSRS中的SSMS 2008 R2报告参数开发一个存储过程。我目前正在填充此参数与此脚本：

Select 
    Null As [program_id], 
    '-All-' As [program_name] 
UNION ALL 
SELECT DISTINCT 
    [program_info_id] AS [program_id], 
    [program_name] 
FROM [evolv_reports].[dbo].[programs_view] 
Order By [program_name] 

但现在的问题是有一个名为“（MS）家庭保存服务”的新程序名。本程序在“-All-”之前列出，因此此报告参数不再默认为“-All-”。我如何使“ - 全部 - ”再次列出？这是我当前参数输出的一部分：

program_id program_name 
406B3C38-D8D3-4ED5-AC5B-9013D3662931 (MS) Family Preservation Services 
NULL         -All- 
F6E2C172-2BFB-45BC-B870-E7BC2414DD91 Adoptions - Agency

Answer 1

SELECT [program_id], [program_name] FROM 
(
    Select 
    Null As [program_id], 
    '-All-' As [program_name] , 
    0 as num1 
    UNION ALL 
SELECT DISTINCT 
    [program_info_id] AS [program_id], 
    [program_name] , 
    1 as num1 
)a 
ORDER BY a.num1, a.[program_name] -- or just by a.num1 if you don't need to sort by program_name 

Answer 2

也许是这样的：

SELECT 
    * 
FROM 
(
Select 
    Null As [program_id], 
    '-All-' As [program_name] 
UNION ALL 
SELECT DISTINCT 
    [program_info_id] AS [program_id], 
    [program_name] 
FROM [evolv_reports].[dbo].[programs_view] 
) AS T 
Order By (CASE WHEN [program_id] IS NULL THEN 0 ELSE 1 END), [program_id]
