我使用下面的代码在某个字符或数字出现后提取分隔字符串中如此多的数据，我希望在提取每个这些值之前提取另一条数据。尽管我确实了解其中的元素，但我并不完全了解代码的工作原理。我只是希望重复拉取的过程并将其整合到查询结果中。

我希望拥有

E/A 值也在分隔字符串内，并且在我每次拉取的值之前都有一个部分，所以我假设我会以某种方式使用这段代码来拉取它：
(SELECT BITOFDATA FROM #SPLITOUTDATA so4 WHERE so4.INDEX1 = so1.INDEX1 AND so4.ROWNUM = so1.ROWNUM +2) AS BITOFDATA
FROM #SPLITOUTDATA so1
WHERE BITOFDATA = '012'
由于某种原因，我只是无法让它工作，因为我对此很陌生，但我认为它相当简单。
对不起，如果我没有很好地解释它。
