-5.6.25-winx64\bin> mysqladmin -u root -p create yiibai Enter password:<回车> 或 D:\software\mysql-5.6.25-winx64\bin> mysql -u root -p Enter password: mysql>create database yiibai;

使用PHP脚本创建数据库 mysql_query() bool mysql_query( sql, connection );

<html>
<head>
<title>创建MySQL数据库</title>
</head>
<body>
<?php
$dbhost = ‘localhost:3036‘;
$dbuser = ‘root‘;
$dbpass = ‘‘;
$conn = mysql_connect($dbhost, $dbuser, $dbpass);
if(! $conn )
{
  die(‘Could not connect: ‘ . mysql_error());
}
echo ‘Connected successfully<br />‘;
$sql = ‘CREATE DATABASE yiibai‘;
$retval = mysql_query( $sql, $conn );
if(! $retval )
{
  die(‘Could not create database: ‘ . mysql_error());
}
echo "Database yiibai created successfully\n"; mysql_close($conn); ?> 
</body> 
</html>

2.建表 CREATE TABLE table_name (column_name column_type);

create table emp(
    id int,
    ename varchar(30),
    age int,
    job varchar(20)
);
