1.检查输入的值是否正确,确保输入的值是一个有效的数字。 2.使用ALTER SEQUENCE语句来修改序列的increment by值,而不是使用CREATE SEQUENCE语句。 3.如果序列已经存在,则可以使用ALTER SEQUENCE ... INCREMENT BY ...语句来修改increment by值。 4.如果序列不存在,则可以使用CREATE SEQUENCE ... INCREMENT BY .....

1、select seq_name.nextval from dual; //假设得到结果5656 2、 alter sequence seq_name increment by -5655; //注意是-(n-1) 3、 select seq_name.nextval from dual;//再查一遍,走一下,重置为1了 4、 alter sequence seq_name increment by 1;//还原 可以写个存储过程,以下是完整的存储过程,然后...

If the synchronization table in the destination database has been associated with a sequence when the task stops, DRS automatically resets the sequence value of the destination database. The auto-increment sequence value is the source database sequence value plus the security margin, and the auto...
