如何從字符串

Question

價值如何從A列中得到查詢的SQL代碼和子這樣的代碼跟

格式：

[very long name | code | subcode] 

的例子

[Pear | S01 | 10] 
[Pineapple | S01 | 9] 

PS：沒有方括號，但管道分隔符是真實的

Answer 1

試試這個; DEMO - UPDATED WITH A TABLE

--declare @s varchar(50)='[Pineapple | S01 | 9]' 

select substring(yourColumn,ind1 + 1,ind2-(ind1 +1)) code, 
     substring(yourColumn,ind2 + 1,len(yourColumn)-(ind2 + 1)) subcode 
FROM ( 
    SELECT yourColumn, charindex('|',yourColumn,1) ind1, 
     charindex('|',yourColumn,charindex('|',yourColumn,1)+1) ind2 
    FROM yourTable 
) X 

Answer 2

假設你的代碼總是三個字母，你可以使用一些內置的功能來幫助你：

WITH Data(Sample) AS 
(
    SELECT 'Pear | S01 | 10' UNION 
    SELECT 'Pineapple | S01 | 9' 
) 
SELECT 
    SUBSTRING([Sample], CHARINDEX(' | ', [Sample], 1) + 3, 3) AS Code, 
    REVERSE(SUBSTRING(REVERSE([Sample]), 1, 
     CHARINDEX(' | ', REVERSE([Sample]), 1) - 1)) AS SubCode 
FROM 
    data
