生成字段的字符类型模式

时间：2017-04-04 22:56:30

标签： sql tsql

我想查看字段的字符内容，然后在该字段中生成字符类型模式的计数。因此，'SomeStuff 123'的值将具有'XXXXXXXXX 999'的模式。

我已经有两种方法可以做到这一点，但它们似乎很长而且很笨拙。我想找到最短/最优雅的方式来做到这一点。

我认为PATINDEX可能是最佳选择：

Select 
    Pattern = 
    Case 
        When PatIndex('%[0-9]%', Left([MyField], 1)) = 1 Then '9' 
        When PatIndex('%[a-Z]%', Left([MyField], 1)) = 1 Then 'X' 
        When PatIndex('% %', Left([MyField], 1)) = 1 Then ' '
        Else '?'
    End 
+ 
    Case
        When PatIndex('%[0-9]%', Substring([MyField], 2, 1)) = 1 Then '9' 
        When PatIndex('%[a-Z]%', Substring([MyField], 2, 1)) = 1 Then 'X' 
        When PatIndex('% %', Substring([MyField], 2, 1)) = 1 Then ' ' 
        Else '?'
    End 
--...

以下是我测试过的几种方法：

Literal REPLACE方法：

Select [MyFieldPattern] = Replace(Replace(Replace(Replace(Replace(Replace(Replace(Replace(Replace(Replace(Replace(Replace(Replace(Replace(Replace(Replace(Replace(Replace(Replace(Replace(Replace(Replace(Replace(Replace (Replace(Replace(Replace(Replace(Replace(Replace(Replace(Replace(Replace(Replace([MyField], 'A','X') ,'B','X') ,'C','X') ,'D','X') ,'E','X') ,'F','X') ,'G','X') ,'H','X') ,'I','X') ,'J','X') ,'K','X') ,'L','X') ,'M','X') ,'N','X') ,'O','X') ,'P','X') ,'Q','X') ,'R','X') ,'S','X') ,'T','X') ,'U','X') ,'V','X') ,'W','X') ,'Y','X') ,'Z','X') ,'0','1') ,'2','1') ,'3','1') ,'4','1') ,'5','1') ,'6','1') ,'7','1') ,'8','1') ,'9','1')

也许是另一种方式

Declare @YourTable table (ID int,MyField varchar(100))
Insert Into @YourTable values
(1,'SomeStuff 123')

Select A.ID
      ,A.MyField
      ,B.*
 From  @YourTable A
 Cross Apply (
                Select NewString=replace(Stuff((Select ''+C From (
                                    Select C=case when C Like '[0-9]' then '9' else
                                             case when C = ' ' then '§§Space§§' else 'X' end end
                                     From (Select Top (len(A.MyField)) C=substring(A.MyField,Row_Number() Over (Order By (Select null)),1) From master..spt_values ) B1
                                   ) C1 For XML Path ('')),1,0,''),'§§Space§§',' ')
             ) B

返回

ID  MyField         NewString
1   SomeStuff 123   XXXXXXXXX 999
