急-数据库复制问题
环境为 sqlserver 2000
现在有a和b两个库
a库中有数据,b库为新建的数据库
我想要将a库中的,表,结构,存储过程,视图,自定义函数等等等(不含数据)复制到库b中
目前,我能想到的思路是
1,delete from tablename 挨个儿删除,但是这样工作量非常大,另外涉及到外键的地方也很麻烦
2,truncate table tablename 这个虽然和上面的delete类似,除了工作量更大一下之外,速度和其他方面比delete要好,但是,
问题是涉及到外键的地方,就报错了,哎...因为数据库比较复杂,生怕弄错了
3,所谓导出sql,这个我倒是导出来了,如何导进去呢? 倒进去还是有几个表要修复.....
求查看表外键,关闭和打开外键相关代码
求思路,求方法,求步骤

------解决方案--------------------
右击数据库-任务-生成脚本 这个里面就有的，你可以自己选择！这样只是把表的结构，储存过程的语句就生成出来了。
