Question

我只想将字符串拆分为MS SQL中的列和行

示例：

字符串：26412|7|554.40#42470|10|1504.40#49606|10|274.40#378982|10|425.84

分隔符：|为列，

分隔符：#为行

帮助找到解决方案提前感谢。

预期产出：

Col1    Col2    Col3
-----------------------
26412    07    554.40
42470    10    1504.40
49606    10    274.40
378982   10    425.84

Answer 1

这可以借助XML来完成：

DECLARE @str nvarchar(max) = N'26412|7|554.40#42470|10|1504.40#49606|10|274.40#378982|10|425.84',
        @xml xml

SELECT @xml = CAST('<s><b>'+REPLACE(REPLACE(@str,'#','</b></s><s><b>'),'|','</b><b>')+'</b></s>' as xml)


SELECT  t.v.value('b[1]','int') as Col1,
        t.v.value('b[2]','int') as Col2,
        t.v.value('b[3]','float') as Col3
FROM @xml.nodes('/s') as t(v)

输出：

Col1    Col2    Col3
26412   7       554,4
42470   10      1504,4
49606   10      274,4
378982  10      425,84

Answer 2

使用here中的一个拆分字符串：

declare @str varchar(max)
set @str='26412|7|554.40#42470|10|1504.40#49606|10|274.40#378982|10|425.84'

;with cte(mainitem)
as
(
select * from [dbo].[SplitStrings_Numbers](@str,'#') b 
)
,cte1 as 
(select *,row_number() over (partition by mainitem order by mainitem) as rn from cte c
cross apply
[dbo].[SplitStrings_Numbers](c.mainitem,'|')  )
select 
max(case when rn=1 then cast(item as varchar(100)) end) as col1,
max(case when rn=2 then cast(item as varchar(100))end) as col2,
max(case when rn=3 then cast(item as varchar(100)) end) as col3
from cte1 
group by mainitem

<强>输出：

26412   7   554.40
378982  10  425.84
42470   10  1504.40
49606   10  274.40

Answer 3

试试这个，

DECLARE @List NVARCHAR(max) = '26412|7|554.40#42470|10|1504.40#49606|10|274.40#378982|10|425.84'

SELECT col1 AS ActualData
    ,PARSENAME(REPLACE(col1, '|', '.'), 4) col1
    ,PARSENAME(REPLACE(col1, '|', '.'), 3) col2
    ,substring(col1, (LEN(col1) - CHARINDEX('|', REVERSE(col1))) + 2, len(col1)) AS Col3
FROM (
    SELECT y.i.value('(./text())[1]', 'nvarchar(4000)') AS col1
    FROM (
        SELECT x = CONVERT(XML, '<i>' + REPLACE(@List, '#', '</i><i>') + '</i>').query('.')
        ) AS a
    CROSS APPLY x.nodes('i') AS y(i)
    ) T

这在我的MySql 5.5中非常适合我

 CREATE TABLE split ( id INT, str VARCHAR(50) );
 INSERT INTO split VALUES (1, 'Smith'), (2, 'Julio|Jones|Falcons'), (3,
 'White|Snow'), (4, 'Paint|It|Red'), (5, 'Green|Lantern'), (6, 'Brown|bag');

        CREATE PROCEDURE SplitColumnsToRows ()
        BEGIN
          DECLARE id1 INT (100);
          DECLARE str1 VARCHAR (100);
          DECLARE done INTEGER DEFAULT 0;
          DECLARE tokens INT DEFAULT 0;
          DECLARE i INT DEFAULT 0;
          DECLARE token VARCHAR (100);
          DECLARE cur CURSOR FOR

            SET i = 1;
            WHILE
