我想将文件路径分成不同的列。以下代码适用于大多数情况，但它不适用于下面的示例案例。在有重复词的情况下似乎不起作用。示例代码最多有三列，但由于某些文件路径较长，因此会重复。使用SQL Sever 2008。
我有数千行，如：
Garden Center|Seeds|Flower Seeds|Organic Flower Seeds
期望的输出：
Path1
Garden Center
Path2
Seeds
Path3
Flower Seeds
Path4
Organic Flower Seeds
目前我正在：
Path1
Garden Center
Path2
Seeds
Path3
Flower Organic Flower Seeds
- 代码：
