怎么分组查询出4条信息。。。
ID UID TUID MSG
1 120 125 sadasf
2 125 120 adaf
3 120 125 asfafaff
4 125 120 afasfa
要如下图效果:

详细描述下需求,根据什么分组。最后结果是什么?
详细描述下需求,根据什么分组。最后结果是什么?
结果跟上面的图片一样
A用户跟B用户的最后通话记录显示在列表 ,然后计算出他们总共有几条信息来玩
sql语句:select * from 表名 where (UID=120 or UID=125) and (TUID=120 or TUID=125),执行这个sql语句,把结果集循环显示就行了,记录集条数就是信息个数
sql语句:select * from 表名 where (UID=120 or UID=125) and (TUID=120 or TUID=125),执行这个sql语句,把结果集循环显示就行了,记录集条数就是信息个数
看清需求不要瞎回答~!!
你这样我一条
select * from 表 where uid = 125 or tuid = 125 就全部查询出来
select * from 表名 where (UID=120 and UID=125) or (TUID=120 and TUID=125)

你自己的说法让人误解,什么叫瞎回答。尼玛,这年头问问题都这么拽了阿 !你写的这个2b语句是确实能读出这4条,但这只下你表里只有120和125对话两个用户对话的情况!算了。。。跑错地方了

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 type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.
