获取光标以结束不定循环并显示临时表数据sql

我有一个带有游标和临时表的sql查询

它不是在temp表的末尾停止，而是进入一个无限循环。我怎样才能阻止这一切？此外，它会显示“xx行受影响”，而不是显示更改的临时表。如何显示更改临时表？

且光标定义为？让我猜你读了#CumLeadTimRep并插入了它？向我们展示整个代码。我保证这可以而且应该在没有光标的情况下完成。@lad2025，用完整的代码更新了问题。@EvaldasBuinauskas更新了问题，因为我使用CTE，所以需要一个光标。@NisalUpendra所以我是对的，您可以循环使用插入到其中的同一个表。你不能只使用两个具有相同结构的表

#CumLeadTimRep_Input

和

#CumLeadTimRep_result

？？？
