Question

我有这样的表

---table 1----------------------------------------------------------
string|
14, 123, A, 1000, 2017-09-10, h, 2, a 
 14, 789, C, 8000, 2017-11-02, m, 2, c
--------------------------------------------------------------------

我想将此表列拆分为8列，并将其插入table2，如下所示：

---table 2----------------------------------------------------------
col1 | col2 | col3 | col4 | col5       | col6 | col7 | col8
14     123    A      1000  2017-09-10     h      2       a
14     789    C      8000  2017-11-02     m      2       c

但我无法做到！

Answer 1

你可以用它。它会对你有用。

CREATE TABLE [dbo].[table1](    
    [col1] [varchar](1000) NULL
) ON [PRIMARY]


CREATE TABLE [dbo].[table2](
    [col1] [varchar](100) NULL,
    [col2] [varchar](100) NULL,
    [col3] [varchar](100) NULL,
    [col4] [varchar](100) NULL,
    [col5] [varchar](100) NULL,
    [col6] [varchar](100) NULL,
    [col7] [varchar](100) NULL,
    [col8] [varchar](100) NULL
) ON [PRIMARY]


INSERT INTO table1(col1) VALUES('1,2,3,4,5,6,7,8')
INSERT INTO table1(col1) VALUES('10,20,30,40,50,60,70,80')

;WITH Split_Names (xmlcol)
AS
(
    SELECT 
    CONVERT(XML,'<ColName><name>'  
    + REPLACE(col1,',', '</name><name>') + '</name></ColName>') AS xmlcol
      FROM table1
)
INSERT INTO table2(col1,col2,col3,col4,col5,col6,col7,col8)
 SELECT    
 xmlcol.value('/ColName[1]/name[1]','varchar(100)') AS col1    
 ,xmlcol.value('/ColName[1]/name[2]','varchar(100)') AS col2
 ,xmlcol.value('/ColName[1]/name[3]','varchar(100)') AS col3
 ,xmlcol.value('/ColName[1]/name[4]','varchar(100)') AS col4
 ,xmlcol.value('/ColName[1]/name[5]','varchar(100)') AS col5
 ,xmlcol.value('/ColName[1]/name[6]','varchar(100)') AS col6
 ,xmlcol.value('/ColName[1]/name[7]','varchar(100)') AS col7
 ,xmlcol.value('/ColName[1]/name[8]','varchar(100)') AS col8
 FROM Split_Names

将一列拆分为多列并插入sql server中的另一个表
