Question

以下是表格结构： -

Table name: Records
---------------------------------------------------------------
| office ID| transactionName | transactionAmount | Date | uid |
---------------------------------------------------------------

我正在尝试从给定订单办公室ID 2,4,1,3中的上表中获取结果。我们如何在ORDER BY子句中指定id，以便输出的顺序符合指定。

Answer 1

您可以使用以下主要定义自定义排序顺序的查询：

SELECT * FROM records
ORDER BY CASE officeID
    WHEN 2 THEN 1 
    WHEN 4 THEN 2 
    WHEN 1 THEN 3 
    WHEN 3 THEN 4
    ELSE 5
   END

Answer 2

为其提供自定义排序顺序

SELECT [office ID], transactionName, transactionAmount, Date, uid
FROM Records
ORDER BY CASE WHEN [office ID] = '2' THEN '1'
              WHEN [office ID] = '4' THEN '2'
              WHEN [office ID] = '1' THEN '3'
              WHEN [office ID] = '3' THEN '4'

Answer 3

这是另一种选择......

IF OBJECT_ID('tempdb..#TempTable', 'U') IS NOT NULL DROP TABLE #TempTable

create table #TempTable
(
  OfficeID int
)

insert into #TempTable (OfficeID) values (1)
insert into #TempTable (OfficeID) values (2)
insert into #TempTable (OfficeID) values (3)
insert into #TempTable (OfficeID) values (4)

declare @CustomSortOrder varchar(100)

set @CustomSortOrder = '2~4~1~3~'

select * from #TempTable

select *
from #TempTable
order by charindex(convert(char(1), #TempTable.OfficeID) + '~', @CustomSortOrder)
