$sql="select username,SUM(IF(types = 1, smoney, 0)) as t1 from record where 1=1".$s1." GROUP BY username";
现在得出的结果是:record 表中username = username的 types 字段 = 1 的 smoney 字段的总和 被赋值为变量 $t1
我想换一个查询条件
希望得出结果是:record 表中username = username的 以及 regfrom 字段中包含 nameuser 的 types 字段 = 1 的 smoney 字段的总和 被赋值为变量 $t1
请问sql语句该怎么写。数据库截图:
回复讨论(解决方案)
包含 nameuser 的 是什么意思?
比如用户admin 查询就查询到 nameuser 这个字段中admin的信息
$username=$_REQUEST['username'];
例:
查询用户为admin
username字段中等于admin
以及 regfrom 字段中包含 admin的
得出的结果为:10+10+20+30+20
查询用户为b123456
username字段中等于b123456
以及 regfrom 字段中包含 b123456 的
得出的结果为:20+30+20
$username=$_REQUEST['username'];$sql="select username, SUM(smoney) as t1 from record where username='$usename'";
regfrom 字段中还要包含 $usename 这一段没有呢?
把条件加上不就行了么?
regfrom 字段中还要包含 $usename 这一段没有呢?
举一反三一下不就有了。
$sql="select username, SUM(smoney) as t1 from record where username='$usename' or instr(regfrom, '$username') >0";

In PHP, you can use session_status() or session_id() to check whether the session has started. 1) Use the session_status() function. If PHP_SESSION_ACTIVE is returned, the session has been started. 2) Use the session_id() function, if a non-empty string is returned, the session has been started. Both methods can effectively check the session state, and choosing which method to use depends on the PHP version and personal preferences.

Managing concurrent session access in PHP can be done by the following methods: 1. Use the database to store session data, 2. Use Redis or Memcached, 3. Implement a session locking strategy. These methods help ensure data consistency and improve concurrency performance.

Load balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1. Session Replication Copy session data between servers. 2. Session stickiness directs user requests to the same server. 3. Centralized session storage uses independent servers such as Redis to store session data to ensure data sharing.

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching

Sessionhijacking refers to an attacker impersonating a user by obtaining the user's sessionID. Prevention methods include: 1) encrypting communication using HTTPS; 2) verifying the source of the sessionID; 3) using a secure sessionID generation algorithm; 4) regularly updating the sessionID.
