使用与全局临时表合并

Question

我遇到了存储过程问题。我正在尝试将表var中的数据合并到全局临时表中。我在合并后将表名称放入时出现错误。这是我第一次尝试使用它。如果我评论合并，一切正常。

有没有人知道问题在哪里？

当我执行的SP，我得到一个错误 “消息102，级别15，状态1，过程Pickrate，109线 附近有语法错误## HoursByDay'。”

Answer 1

检查数据库的兼容性级别。

我可以将其设置为2000或2005年。2008年重现此错误，一旦我删除你的基表的所有引用它工作正常（虽然MERGE语句需要用分号来终止。）

Answer 2

尽管the documentation似乎没有明确提及#temp或##全局临时表，但我从来没有见过使用它们的MERGE示例。也许是因为MERGE ##HoursByDay应该是MERGE INTO ##HoursByDay？也许是因为前面的陈述没有用分号恰当地结束？不在我现在可以测试的地方，但我会尝试这些。

无论如何，你为什么不使用永久表？除了最后不必删除它之外，它可以实现与##全局临时表相同的并发和隔离。我不明白全球临时表在这里买你什么。
