SSIS中的fast。因此，通常，我喜欢将数据流传输到一个表，然后使用SQL语句执行set操作

在您的情况下，不太清楚SSI是否正在做大量它擅长的工作（数据透视、排序、聚合、查找、异构数据、脚本、验证）（您在SSI外部联合，然后在SSI中拆分并为生成的行调用各个SP），所以我只是把它扔出去。

这个特殊的进程不接受任何参数。非常有信息性的链接。这很有趣。我会尝试一下，看看会发生什么。不管是哪种顺序（asc/desc），都可以按顺序抛出订单。添加订单会增加执行计划的时间，最后一次选择可能是在插入开始之前完成的。我将研究此特定连接（停用）的含义，以及它在同时插入时可能挂起的原因。不幸的是，未检测到锁，使用表提示拒绝锁定/强制锁定无效。我将尝试此设置。如果我必须重写程序和包，我可能会走这条路，谢谢。
