在SQLSERVER中每个会话,即每个查询分析器窗口都会产生一个SQL进程,对于那些持续时间短的进程,它们转瞬即失,而对于持续时间比较长的,我们需要希望查看它的运行状态,就可以借助SQL提供的sp_who命令,下面是对它的具体介绍,,主要选自MSDN.
sp_who [ [ @loginame = ] 'login' | session ID | 'ACTIVE' ]
你可以在sp_who后面加你的SPID号(sessionID),登陆名,线程状态等
下面对status执行状态作一个简单的说明,选自MSDN
background:会话正在运行一个后台任务,例如死锁检测。
rollback: 会话具有正在处理的事务回滚。
pending: 会话正在等待工作线程变为可用。
runnable: 会话的任务在等待获取时间量程时位于计划程序的可运行队列中。
spinloop: 会话的任务正在等待调节锁变为可用。
suspended: 会话正在等待事件(如 I/O)完成。
注意:如果你的代码处理数据比较大,SQL会创建子线程进行并行处理,子线程的标示为ecid。
别外,如果希望查看SQL进程的详细信息,可以使用下面代码
SELECT * FROM sys.sysprocesses

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
