解决方案

因此，您必须将值（500）存储在一些额外的表或设置表中，并在重新生成之前将其读取

Suppose I created the sequence generator which generates 500 values,then if I drop it and recreate it how I can know that it generates sequence from 501.

What I have tried:

Suppose I created the sequence generator which generates 500 values,then if I drop it and recreate it how I can know that it generates sequence from 501.

解决方案

For that reason you must store your value (500) in some extra table or a settings table and read it before re-generating.
