我想要從值列

預期產出3列

val1 val2 val3 

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

需要查詢幫助

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; 

此代碼

• 允許不同的成分值長度
• 假定x是總是隔板
• 假定總是3個分量
