高级创建：复制表：复制数据!

--新建表：

create table table1( id varchar(300) primary key, name varchar(200) not null);

--修改表名： alter table table1 rename to table2;

 

--表数据复制：

insert into table1 (select * from table2);

sql 复制 --两表结构一致的情况

insert into pub_REE_DATA select *from r_data where cons_no=?

 

--复制表结构： create table table1 select * from table2 where 1>1;

 

--复制表结构和数据：create table table1 select * from table2;

create table ACCT_DEPOSIT_ACCOUNTS_20180209 as select *From ACCT_DEPOSIT_ACCOUNTS;

 

--复制指定字段： create table table1 as select id, name from table2 where 1>1;

--条件查询： select id,name (case gender when 0 then '男' when 1 then ‘女’ end ) gender from table1
