CREATE TABLE new_tbl_name SELECT * FROM old_tbl_name / INSERT INTO new_tbl_name SELECT * FROM old_tbl_name的相关文章

【SQL篇章--CREATE TABLE】

[SQL篇章][SQL语句梳理 :--基于MySQL5.6][已梳理:CREATE TABLE][会坚持完善] SQL : 1. Data Definition Statements: 1.3 CREATE TABLE 格式:3种建表语句 1.简单SQL表明结构: CREATE TABLE t7(id INT ,NAME VARCHAR(20), PRIMARY KEY(`id`)) ENGINE=INNODB; 格式: CREATE [TEMPORARY] TABLE [IF NOT EXIS

CREATE TABLE常用命令

CREATE TABLE students( stuID INTEGER NOT NULL , stuname char(30) not null, sex int NOT NULL ); CREATE TABLE students( stuID INTEGER NOT NULL , stuname char(30) not null, sex int NOT NULL, PRIMARY KEY (stuID) ); CREATE TABLE students( stuID INTEGER NO

oracle数据库【表复制】insert into select from跟create table as select * from 两种表复制语句区别

create table as select * from和insert into select from两种表复制语句区别 [sql] view plain copy create table targer_table as select * from source_table insert into target_table(column1,column2) select column1,column2 from source_table 以上两句都是将源表source_table的记录插

create table xxx as select 与 create table xxx like

insert table 和create table as 区别

insert into table1(columns1,columns2) select columns1,columns2 from table2; 从table2中查询的结果插入到table1中,前提是table1和table2已经存在; oracle中不支持 select columns1 into table2 from table1; 其语法为 create. as..select,有以下三种方式: 1. create table table1 as selec

CREATE TABLE 表名 AS SELECT 语句

1.新表不存在复制表结构即数据到新表 ? 1 2 create table new_table select * from old_talbe; 这种方法会将old_table中所有的内容都拷贝过来,用这种方法需要注意,new_table中没有了old_table中的primary key,Extra,auto_increment等属性,需要自己手动加,具体参看后面的修改表即字段属性.只复制表结构到新表 ? 1 2 3 4 5 6 # 第一种方法,和上面类似,只是数据记录为空,即给一个false

create table b1 as select * from b建表锁表测试

A: create table a1 like a; insert into a1 as select * from a; B: create table b1 as select * from b; 测试AB两种建表语句对原始表的影响.其中a.b的数据量均为300000 rows. 如果使用A种方式建表,insert过程可能会堵塞DML操作(根据innodb mvcc原理) 如果使用B中方式建表,此建表过程全程锁表: 建议:生产环境使用A种方式建备份表:

sqlserver不能直接create table as select

sqlserver不能直接create table as select 在sqlserver 下想复制一张表的,想到oracle下直接create table xxx as select * from ....即可.但是结果却是错误的,baidu一下发现.sqlserver的语法是 : select * into tablenew from tableold Insert into select 与create table as的性能测试及create table 2013-10-05 09:5

create table like 和create table select 比较

语法: CREATE [TEMPORARY] TABLE [IF NOT EXISTS] tbl_name [(create_definition,...)] [table_options] [select_statement] CREATE [TEMPORARY] TABLE [IF NOT EXISTS] tbl_name [(] LIKE old_tbl_name [)]; 测试过程: 原数据表: mysql> show create table test_or
