On my SQL Server, I have a query which does not produce any rows and this select statement runs for about a minute. Now I don't understand why the insert would not finish forever. The destination table has only 48k rows. I don't have rights to run any kinds of tracing or any other diagnostic queries that can help this. What else can I try?

将插入物转换为选择，以便您可以看到要插入的内容。然后从SQL语句（连接，子查询等）中取出部分，直到它开始快速运行。你删除的最后一件事是缓慢的原因。如果没有示例，我们无法为您提供更具体的帮助。编写https://stackoverflow.com/help/mcve的过程可能会帮助您自己回答。
