Question

希望多次根据相同的分隔符在一列中拆分字符串，并将每个字符串数组输入到同一个表中的单独的表列中，例如。

DECLARE @Test VARCHAR(50)
SET @Test = '0^5^6^104^0^0^5'

预期输出

column1 column2 column3 column4 column5 column6 column7
0 5 6 104 0 0 5

Answer 1

DECLARE @Test table (val VARCHAR(50))
insert into @Test (val)values  ('0^5^6^104^0^0^5')




;WITH CTE AS (
SELECT   
     Split.a.value('.', 'VARCHAR(100)') AS String  
 FROM  (SELECT   
         CAST ('<M>' + REPLACE([val], '^', '</M><M>') + '</M>' AS XML) AS String  
     FROM  @Test) AS A CROSS APPLY String.nodes ('/M') AS Split(a))
     Select [1]Col1,[6]Col2,[7]Col3,[4]Col1,[2]Col1,[3]Col1,[5]Col1 from (
     select T.RN,T.String from (
     select Row_number()OVER( ORDER BY string )RN,string from CTE)T)K
     PIVOT(MAX(string) FOR RN IN ([1],[2],[3],[4],[5],[6],[7]))P

Answer 2

DECLARE @Test VARCHAR(50)
SET @Test = '0^5^6^104^0^0^5'

select * from (
select t.col.value('.','varchar(max)') as val, 'column' + cast(ROW_NUMBER() over (order by (select 1)) as varchar(10)) as rn from
    (
        select cast('<m>' + REPLACE(@test,'^','</m><m>') + '</m>' as xml) as val
    ) as abc
    cross apply abc.val.nodes('/m') as t(col)
              ) as t1
              pivot (max(val) for rn in (column1,column2,column3,column4,column5,column6,column7)) as pvt

Answer 3

试试这个

DECLARE @Test VARCHAR(50)
SET @Test = '0^5^6^104^0^0^5'
SET @Test = N'SELECT N''' + REPLACE(@Test,'^',''' ,''') + ''''
exec(@Test)

T-SQL基于分隔符拆分列，并将拆分字符串数组输入到多个表列中
