Question

我正在使用Microsoft SQL。首先让我解释一下，当我输入的数据没有所有的cn和路径以及xml数据时，此SQL脚本中的“ splitter”命令就可以使用。如果数据以

的形式出现

testrole|testrole2|testrole3

我正在尝试将其引入原始数据中。它仍将以管道分隔，但在角色/访问名称之后会有更多的字符串数据。因此，我以后可以使用它批量编写脚本。

我希望最终结果是用户ID-角色，并为具有多个角色的用户显示重复的用户ID。

1-TestRole

2-TestRole

2-TestApp

3-TestApp

关于如何使它起作用的任何想法？您可以看到某些用户将具有一个角色，而其他多个角色。

SELECT
    *
FROM
    @TempUserObjects

--Splitter Statement
SELECT
    tuo.UserID,
    SUBSTRING('|' + tuo.AssignedRoles + '|', ct.UserID + 1, CHARINDEX('|', '|' + tuo.AssignedRoles + '|', ct.UserID + 1) - ct.UserID - 1) AS 'NRFAssignedRoles'
INTO
    #RolesStage2
FROM 
    @CountTable ct
CROSS JOIN
    @TempUserObjects tuo
WHERE
    ct.UserID < LEN('|' + tuo.AssignedRoles + '|')
    AND SUBSTRING('|' + tuo.AssignedRoles + '|', ct.UserID, 1) = '|'

--Shows SubstringCharindex works
SELECT
    SUBSTRING(AssignedRoles, 4, CHARINDEX(',', AssignedRoles) - 4) AS 'SubstringCharindex'
FROM
    @TempUserObjects

SELECT *
FROM #RolesStage2
