select * from gs_grid_info as of timestamp to_timestamp('2013-05-09 9:00:47', 'yyyy-mm-dd hh24:mi:ss');

Java代码

Java代码

允许数据表行移动

** 差异

select * from B minus select * from A;

比较表结构相同的两表之间的差异用minus。

select * from gs_grid_info minus

select * from gs_grid_info as of timestamp to_timestamp('2013-05-09 9:00:47', 'yyyy-mm-dd hh24:mi:ss');
