步骤:

1. 先将源库备份, 在另一台机上将备份文件还原作为目标库;

2. 将源库上所有的外键、以及用优化顾问生成的视图 ( 以'dta_mv_' 开头的 ) ,删除脚本导出为 before.sql, 创建脚导出为after.sql;

3. 在目标库上执行 before.sql;

4. 执行复制操作;

5. 在目标库上执行 after.sql;


需要注意的事项:

1. 两库的所有的表结构必须一致, 甚至列的顺序都不能变动, 否则 SqlBulkCopy 不认!

2. SqlBulkCopy 的创建应该是: SqlBulkCopy bulkCopy = new SqlBulkCopy(outerConn, SqlBulkCopyOptions.KeepIdentity | SqlBulkCopyOptions.KeepNulls,  null).AddTimeout();

如果不按这个, 标识列无法按原来的插入;  参考文章: sqlbulkcopy 批量插入数据
