一、新表不存在
1、create table cs as select * from t_aly_il_result ---备份结构和数据
2、create table cs1 as select * from t_aly_il_result where 1 = 0 ---复制结构
3、create table cs2 as select up_inst_id,aly_layer from t_aly_il_result --复制部分字段
二、新表已存在(以下必须先创建表)
前提条件:create table cs3 as select * from t_aly_il_result where 1 = 0 --表结构已存在
1、复制数据
select * from cs3 ---没数据的表
insert into cs3 select * from t_aly_il_result; --复制数据到新表
2、select
*
into
new_table
from
old_table;
3、select
*
into
new_table
from
old_table where 1=2;
