php mysql insert语句的问题?
phpcms 系统中有个sql语句(添加文章内容),我将其执行的sql语句记录到文件中,发现有一个字段没有插入,也没有默认值,不知道这个sql语句是怎样执行成功的,我在phpmyadmin中执行语句就会报错。
下面的sql语句中并没有typeid这个字段,这个字段是非空的,且没有默认值。(数据表名字已替换)
<code>INSERT INTO `somedb`.`news`(`hascode`,`style`,`thumb`,`inputtime`,`islink`,`catid`,`title`,`keywords`,`description`,`posids`,`status`,`updatetime`,`username`,`sysadd`) VALUES ('0','','','1452096000','0','1','看看这些情况是怎么回事呢?','回事 情况','再来看看这些情况是怎么回事呢?','0','99','1452133458','wenhua','1')</code>
上面的错误是同样的sql语句在phpmyadmin中执行的,但是phpcms系统中却能成功执行,不知道这是怎么回事?

帖一下表定义给我们看看:
<code>show create table 表名;</code>
你这个报错是zhenbenling.news表的typeid字段没有默认值(且它不允许null值),你插入的时候,必须给这个字段值的!哪怕是''!
你想方便的话,修改下这列的约束:
<code>use zhenbenling; alter table news change typeid typeid smallint(5) NOT NULL DEFAULT ''; </code>
你确定insert那条记录,在phpcms中能查到吗?phpadmin报错是正常的,就应该报错。
给typeid字段默认值,或者允许为空

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

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 remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

The reasons why PHP is the preferred technology stack for many websites include its ease of use, strong community support, and widespread use. 1) Easy to learn and use, suitable for beginners. 2) Have a huge developer community and rich resources. 3) Widely used in WordPress, Drupal and other platforms. 4) Integrate tightly with web servers to simplify development deployment.

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

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.
