Question

我有“ GUI_KVLevelName”列。它的数据为：

500.00 / 69.00 / 34.50
500.00 / 400.00 / 138.00
500.00 / 69.00
500.00 / 400.00
500.00 / 345.00 / 34.50
57.00 / 8.30

我想与此一起使用订购。这是一个varchar列，但我想将其定为数字。那么我如何使用此列的订单？

Answer 1

这可能有用一点作弊

通过删除小数点，我们将各个值转换为更大的INT。然后将其转换为hierarchyid类型，然后进行排序

示例

Declare @YourTable Table ([GUI_KVLevelName] varchar(50))
Insert Into @YourTable Values 
 ('500.00/69.00/34.50')
,('500.00/400.00/138.00')
,('500.00/69.00')
,('500.00/400.00')
,('500.00/345.00/34.50')
,('0.45/5.30')          -- Added for leading zero
,('0.10/9.30')          -- Added for leading zero

Select *
 From @YourTable
 Order By try_convert(hierarchyid,replace('/'+replace([GUI_KVLevelName],'.','1')+'/','/0','/'))

返回

GUI_KVLevelName
0.10/9.30
0.45/5.30
500.00/69.00
500.00/69.00/34.50
500.00/345.00/34.50
500.00/400.00
500.00/400.00/138.00

Answer 2

第二个答案，以防您无法将GTD保留两位小数。

示例

Declare @YourTable Table ([GUI_KVLevelName] varchar(50))
Insert Into @YourTable Values 
 ('500.00/69.00/34.50')
,('500.00/400.00/138.00')
,('500.00/69.00')
,('500.00/400.00')
,('500.00/345.00/34.50')
,('0.45/5.30')
,('0.1/9.30')
,('0.01/9.30')
,('0.05/9.30')
,('1.3/4.30')

Select A.*
 From @YourTable A
 Cross Apply (
                Select Pos1 = xDim.value('/x[1]','money')
                      ,Pos2 = xDim.value('/x[2]','money')
                      ,Pos3 = xDim.value('/x[3]','money')
                      ,Pos4 = xDim.value('/x[4]','money')
                      ,Pos5 = xDim.value('/x[5]','money')
                      ,Pos6 = xDim.value('/x[6]','money')
                      ,Pos7 = xDim.value('/x[7]','money')
                From  (Select Cast('<x>' + replace([GUI_KVLevelName],'/','</x><x>')+'</x>' as xml) as xDim) as A 
             ) B
 Order By Pos1,Pos2,Pos3,Pos4,Pos5,Pos6,Pos7

返回

GUI_KVLevelName
0.01/9.30
0.05/9.30
0.1/9.30
0.45/5.30
1.3/4.30
500.00/69.00
500.00/69.00/34.50
500.00/345.00/34.50
500.00/400.00
500.00/400.00/138.00
