... 

我想要从值列

预期产出3列

val1 val2 val3 

100 200 300 
200 400 500 
... 
... 

需要查询帮助

Answer 1

SELECT SUBSTRING([VALUE],1,3) AS val1, 
     SUBSTRING([VALUE],5,3) AS val2, 
     SUBSTRING([VALUE],9,3) AS val3 
    FROM TABLE1 

Answer 2

它利用PARSENAME而不是SUBSTRING。

SELECT 
    PARSENAME(Value2, 3) AS val1, 
    PARSENAME(Value2, 2) AS val2, 
    PARSENAME(Value2, 1) AS val3 
FROM 
    (
    SELECT 
     REPLACE(Value, 'x', '.') AS Value2 
    FROM 
     MyTable 
    ) T; 

此代码

• 允许不同的成分值长度
• 假定x是总是隔板
• 假定总是3个分量
