oracle 的alter sequence语法 一、ALTER SEQUENCE语法概述 在Oracle数据库中，ALTER SEQUENCE语句用于修改已存在的序列对象的属性。通过ALTER SEQUENCE语法，用户可以改变序列对象的起始值、递增量、最小值、最大值、循环属性和缓存值等属性。二、ALTER SEQUENCE语法详解 1.修改序列的起始值 用户可以使用ALTER SEQUENCE语句...
在Oracle中，对sequence进行修改的前提是你必须是该sequence的所有者，或者拥有ALTER ANY sequence的权限。对于sequence的参数调整，除了start值之外，你都可以进行操作。例如，如果你想增加序列值的增量为10，最大值设置为10000，并启用循环模式（即达到最大值后重新从头开始），可以使用以下命令：ALTER sequen...
