MySQL 插入数据

学习于插入数据

命令行插入数据

INSERT INTO table_name(field1, field2, … , fieldN)
VALUES
(value1, value2, …, valueN);

实例：

root@host# mysql -u root -p password;
root@host# mysql -u root -p password;
Enter password:*******
mysql> use BigBoss;
Database changed
mysql> INSERT INTO bigboss_tbl 
    -> (bigboss_title, bigboss_author, submission_date)
    -> VALUES
    -> ("学习 PHP", "大老板", NOW());
Query OK, 1 rows affected, 1 warnings (0.01 sec)
mysql> INSERT INTO bigboss_tbl 
    -> (bigboss_title, bigboss_author, submission_date)
    -> VALUES
    -> ("学习 MySQL", "大老板", NOW());
Query OK, 1 rows affected, 1 warnings (0.01 sec)
mysql> INSERT INTO bigboss_tbl 
    -> (bigboss_title, bigboss_author, submission_date)
    -> VALUES
    -> ("学习 Java", "大老板", NOW());
Query OK, 1 rows affected (0.00 sec)
mysql>

PHP 插入数据

mysqli_query(connection,query,resultmode);

<?php
$dbhost = 'localhost';  // mysql服务器主机地址
$dbuser = 'root';            // mysql用户名
$dbpass = '123456';          // mysql用户名密码
$conn = mysqli_connect($dbhost, $dbuser, $dbpass);
if(! $conn )
{
  die('连接失败: ' . mysqli_error($conn));
}
echo '连接成功<br />';
// 设置编码，防止中文乱码
mysqli_query($conn , "set names utf8");
 
$bigboss_title = '学习 Python';
$bigboss_author = 'BigBoss';
$submission_date = '2016-03-06';
 
$sql = "INSERT INTO bigboss_tbl ".
        "(bigboss_title, bigboss_author, submission_date) ".
        "VALUES ".
        "('$bigboss_title','$bigboss_author','$submission_date')";
 
 
 
mysqli_select_db( $conn, 'RUNOOB' );
$retval = mysqli_query( $conn, $sql );
if(! $retval )
{
  die('无法插入数据: ' . mysqli_error($conn));
}
echo "数据插入成功\n";
mysqli_close($conn);
?>

对于含有中文的数据插入，需要添加 mysqli_query($conn , “set names utf8”); 语句。
读取数据表数据可以用 select * from bigboss_tbl;
