ssis-2019 - 在SSIS中将逗号分隔的字符串列拆分为几行？

Question

我想根据第一个表的输入在第二个表中实现输出。我想通过 SSIS 包做到这一点。

假设您的源表只有一个两元素 CSV，我们可以在这里尝试联合方法：

SELECT
    ID,
    SUBSTRING([Group], 1, CHARINDEX(',', [Group]) - 1) AS [Group],
    SUBSTRING([Category], 1, CHARINDEX(',', [Category]) - 1) AS Category
FROM yourTable
WHERE
    [Group] IS NOT NULL
UNION ALL
SELECT
    ID,
    SUBSTRING([Group], CHARINDEX(',', [Group]) + 1, LEN([Group])),
    SUBSTRING([Category], CHARINDEX(',', [Category]) + 1, LEN([Category]))
FROM yourTable
WHERE
    [Group] IS NOT NULL
UNION ALL
SELECT ID, [Group], Category
FROM yourTable
WHERE [Group] IS NULL
ORDER BY
    ID,
    [Group];
