创建数据的语法
2

1、基本语法
3

create database tour character set gbk;
4

use tour;
6

无主键自增长的
7

create table EMB_T_Employee
8

(
9

emb_c_operatorID int not null,
10

emb_c_empCode varchar(255) not null,
11

emb_c_gender int not null,
12

emb_c_email varchar(255) not null,
13

emb_c_empMPhone varchar(255) not null,
14

emb_c_empTel varchar(255),
15

emb_c_empZipCode varchar(50),
16

emb_c_empPID varchar(50),
17

emb_c_empBirthDate datetime,
18

emb_c_empAddress varchar(512),
19

emb_c_regDate datetime not null,
20

emb_c_displayOrder int not null,
21

primary key (emb_c_operatorID)
22

)engine=INNODB default charset=gbk;
23

有主键自增长不控制主键的起点
24

create table emb_t_dictBusType
25

(
26

emb_c_busTypeID int not null auto_increment,
27

emb_c_busTypeEnName varchar(255) not null,
28

emb_c_busTypeZhName varchar(255) not null,
29

primary key(emb_c_busTypeID)
30

)engine=INNODB default charset=gbk;
31

有主键自增长控制主键的起点
32

create table emb_t_dictBusType
33

(
34

emb_c_busTypeID int not null auto_increment,
35

emb_c_busTypeEnName varchar(255) not null,
36

emb_c_busTypeZhName varchar(255) not null,
37

primary key(emb_c_busTypeID)
38

)engine=INNODB auto_increment=1001 default charset=gbk;
39

2、查看当前所有的数据
40

show databases;
41

3、查看当前数据库的所有表
42

show tables;
43

4、查看表结构
44

desc emb_t_dictBusType ;
45

5、查看字符集
46

show variables like 'collation_%';
47

show variables like 'character_set_%';
48

6、修改数据库的字符集
49

alter database tour character set utf-8;
