提醒:
创建 MySql 的表时,表名和字段名外面的符号 ` 不是单引号,而是英文输入法状态下的反单引号,键盘左上角 esc 按键下面的那一个 ~ 按键。
在每一条语句的终止符都是‘;’
一、命令行建库表
[[email protected] ~]# mysql -uroot -p
Enter password:
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MySQL connection id is 36
Server version: 5.7.18-log Source distribution
Copyright (c) 2000, 2017, Oracle, MariaDB Corporation Ab and others.
Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement.
MySQL [(none)]> create database linuxview;
Query OK, 1 row affected (0.00 sec)
MySQL [(none)]> use linuxview;
Database changed
MySQL [linuxview]> create table lv1(id int(4),name varchar(10),mark varchar(10)) engine=innodb default charset=utf8;
Query OK, 0 rows affected (0.40 sec)
MySQL [linuxview]> show tables;
+---------------------+
| Tables_in_linuxview |
+---------------------+
| lv1 |
+---------------------+
1 row in set (0.00 sec)
MySQL [linuxview]>
说明:
如果不想字段为空,可以在字段属性后添加 not null,在插入数据的时如果该字段为NULL会报错。
engine设置搜索引擎
charset设置编码
二、PHP建库表
语法:
mysqli_query(connection,query,resultmode);
{
die(‘创建数据库失败:‘ . mysqli_query($conn));
}
echo "创建数据表成功\n";
mysqli_close($conn);
?>
[[email protected] web]#
效果:
查看数据库:
MySQL [(none)]> use viewtest;
Database changed
MySQL [viewtest]> show tables;
+--------------------+
| Tables_in_viewtest |
+--------------------+
| lv1 |
+--------------------+
1 row in set (0.00 sec)
MySQL [viewtest]>
