我遇到的问题涉及AFTER Insert触发器中使用的MERGE语句。情况是我们有一个表是库存事务的历史记录，调用此表A.当记录插入表A时，会触发AFTER INSERT触发器。此触发器包含两个MERGE语句以更新表B，然后更新表C.表C的MERGE连接到表B，因此我们不重复计算。表B和表C是两个单独的库存交易汇总，以显示可用的库存。下面我贴了一些伪代码的触发器。
80％的时间都有效。另外20％的时间没有发生更新。我已经验证这不是一个逻辑问题，好像我们手动运行插入记录的合并语句，然后他们将适当地更新表B和表C中的目标记录。使用了探查器和扩展事件来尝试捕获未正确更新的实例，但无法正常处理数千个事务。触发器是我认为唯一的选项，因为客户端要求更新是实时的。我已经验证了我的所有合并语句都是正确的，它似乎就像触发器触发时它没有从插入的表中适当地拾取记录。我通过在合并中匹配的唯一键分组插入了多个记录，因此不是这个。不知所措，并会采取任何建议。
编辑：用实际代码替换伪代码
