如何分割行和列值

Question

使用SQL Server 2005

id value1 value2 

001 200 300 
002 200x300 400x200 
003 300x200 500x600 
004 100 200 
..... 

我想值列拆分成2列

If value1 row 200x300 then it should display value1 - 200 and value2 - 300 
if value2 row 400x200 then it should display value1 - 400 and value2 - 200 

預計輸出

id value1 value2 

001 200 300 
002 200 300 
002 400 200 
003 300 200 
003 500 600 
004 100 200 
.... 

如何做這個。

需要SQL查詢幫助

Answer 1

嘗試這個

select * from 
(
select * from Table2 where CHARINDEX('x',value1)=0 and CHARINDEX('x',value2)=0 
union all 
select ID, 
CASE WHEN CHARINDEX('x',value1)>0 then LEFT(value1,CHARINDEX('x',value1)-1) END as value1, 
CASE WHEN CHARINDEX('x',value1)>0 then RIGHT(value1,CHARINDEX('x',value1)-1) else value2 end as value2 
from Table2 
where CHARINDEX('x',value1) > 0 
union all 
select ID, 
CASE WHEN CHARINDEX('x',value2)>0 then LEFT(value2,CHARINDEX('x',value2)-1) END as value1, 
CASE WHEN CHARINDEX('x',value2)>0 then RIGHT(value2,CHARINDEX('x',value2)-1) else value2 end as value2 
from Table2 
where CHARINDEX('x',value2) > 0 
) a 
order by 1 

Answer 2

請這個嘗試..

--Create Table : 
    Create Table #Temp 
    (
    Id Varchar(10), 
    Value1 Varchar(10), 
    Value2 Varchar(10) 
    ) 

    --Insert Values : 
    Insert into #Temp Values ('001','200','300') 
    Insert into #Temp Values ('002','200x300','400x200') 
    Insert into #Temp Values ('003','300x200','500x600') 
    Insert into #Temp Values ('004','100','200') 

    --View Data : 
    Select * from #Temp 

    --Query for Exepected OutPut : 
    Select Id,Value1,Value2 from #Temp Where ( Value1 not Like '%x%' and Value2 not Like '%x%') 
    Union all 
    Select Id, 
    SUBSTRING(Value1,1,CharIndex('x',Value1)-1) as Value1, 
    SUBSTRING(Value1,CharIndex('x',Value1)+1,Len(Value1)) as Value2 
    from #Temp Where (Value1 Like '%x%' ) 
    Union all 
    Select Id, 
    SUBSTRING(Value2,1,CharIndex('x',Value2)-1) as Value1, 
    SUBSTRING(Value2,CharIndex('x',Value2)+1,Len(Value2)) as Value2 
    from #Temp Where (Value2 Like '%x%' ) 
    Order by ID 

    --Clean Up: 
    Drop table #Temp 

Answer 3

請檢查：在什麼基礎上

DECLARE @table as TABLE(id nvarchar(10), Value1 Nvarchar(50), Value2 nvarchar(50)) 
insert into @table values 
('001', '200', '300'), 
('002', '200x300', '400x200'), 
('003', '300x200', '500x600'), 
('004', '100', '200') 

select id, Value1, Value2 From @table 
select id, Value1, Value2 From @table where CHARINDEX('x', Value2)=0 
union all 
select id, SUBSTRING(Value1, 1, CHARINDEX('x', Value1)-1) Value1, SUBSTRING(Value1, CHARINDEX('x', Value1)+1, LEN(Value1)) Value2 From @table where CHARINDEX('x', Value2)>0 
union all 
select id, SUBSTRING(Value2, 1, CHARINDEX('x', Value2)-1) Value1, SUBSTRING(Value2, CHARINDEX('x', Value2)+1, LEN(Value1)) Value2 From @table where CHARINDEX('x', Value2)>0 
order by id
