Question

我对SQL很陌生，而且最近的任务已经过时了。这个程序是我使用一个正常运行的SP构建的，有一些小的改动。

这仍然是失败的，我不明白为什么，有经验的人可以扫描一下并解释我哪里出错了吗？或提供任何意见？

这应该包含给定@acctgrp中每个帐户的数据行。每个月都应该有一列我们有A.TotalAllExtendedCostLessExcludedItems, A.GenericPercentSource个数据。

这个项目对我来说只是第一次。这是一次很棒的学习经历，但我处在一个无法攀爬的洞里。

DECLARE @MonthString varchar(max), @SQL varchar(max), @FirstMonth varchar(7),

---not certain what this does exactly, but I did my best to logically mimic the template I was given
