为什么 INSERT INTO MYSQL 数据库失败?
当我用
<span class="x">$sql = "INSERT INTO MSG_TEST(HOUSE_ID,HOUSE_TYPE,PV,UV,CITY_ID,DATELINE) VALUES(13044064,5,6,5,2600,20130227);"; </span>
回复内容:
输出mysql_error();看看。好像php为了系统安全,不能一次执行多条sql语句。
你换成
<span class="err">$</span><span class="k">sql</span> <span class="o">=</span> <span class="ss">"INSERT INTO MSG_TEST(HOUSE_ID,HOUSE_TYPE,PV,UV,CITY_ID,DATELINE) </span> <span class="ss">VALUES</span> <span class="ss">(13044064,5,6,5,2600,20130227),</span> <span class="ss">(1425578,8,6,5,2500,20130227),</span> <span class="ss">(18705325,1,3,3,801,20130227)"</span><span class="p">;</span> <span class="err">看看</span>
回答: 第一,mysql_query函数不允许一次执行多条SQL语句的,还有一个函数好像是 mysql_query_multi (),你查找下函数库或手册; 第二,从你提供的SQL语句看,为了执行性能的高效,写成: INSERT INTO MSG_TEST(HOUSE_ID,HOUSE_TYPE,PV,UV,CITY_ID,DATELINE) VALUES(13044064,5,6,5,2600,20130227),(1425578,8,6,5,2500,20130227)....;
mysql_query
(PHP 4, PHP 5)
mysql_query — 发送一条 MySQL 查询
说明
resource mysql_query
( string $query
[, resource $link_identifier
] )
mysql_query()
向与指定的连接标识符关联的服务器中的当前活动数据库发送一条查询。如果没有指定
link_identifier,则使用上一个打开的连接。如果没有打开的连接,本函数会尝试无参数调用
mysql_connect()
函数来建立一个连接并使用之。查询结果会被缓存。
Note:
查询字符串不应以分号结束。
不支持多条语句一起查询。 你确信你写的insert是对的?回去翻翻手册吧。

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security.
