  以下的文章主要是介绍MySQL5创建存储过程的实例演示,MySQL5创建存储在实际操作中应用的频率还是很高的,以下就是MySQL5创建存储过程的实例具体描述,希望在你今后的学习中会有所帮助。

  1 用mysql客户端登入

  2 选择数据库

  mysql>use test

  3 查询当前数据库有哪些存储过程

  mysql>show procedure status where Db='test'

  4 创建一个简单的存储过程

  mysql>create procedure hi() select 'hello';

  5 存储过程创建完毕,看怎么调用它

  mysql>call hi();

  显示结果 mysql> call hi();

  +-------+
  | hello |
   +-------+
   | hello |
  +-------+
  1 row in set (0.00 sec) Query OK, 0 rows affected (0.01 sec)

  6 一个简单的储存过程就成功了,这只是一个演示,存储过程可以一次执行多个sql语句,所以php只连接数据库一次就能查询多个语句;不过要返回多个结果集就必须用mysqli扩展来查询,否则会提示错误can't return a result set in the given context,所以要使用这些新功能,最好适应使用mysqli的php扩展库

  函数的用法类似,就是多了一个返回值,以上的相关内容就是对MySQL5创建存储过程实例的介绍,望你能有所收获。

What is cache? A cache (pronounced ka·shay) is a specialized, high-speed hardware or software component used to store frequently requested data and instructions, which in turn can be used to load websites, applications, services, and other aspects of the system faster part. Caching makes the most frequently accessed data readily available. Cache files are not the same as cache memory. Cache files refer to frequently needed files such as PNGs, icons, logos, shaders, etc., which may be required by multiple programs. These files are stored in your physical drive space and are usually hidden. Cache memory, on the other hand, is a type of memory that is faster than main memory and/or RAM. It greatly reduces data access time since it is closer to the CPU and faster compared to RAM

For students who are familiar with database operations, writing beautiful SQL statements and finding ways to find the data they need from the database is a routine operation. For students who are familiar with machine learning, it is also a routine operation to obtain data, preprocess the data, build a model, determine the training set and test set, and use the trained model to make a series of predictions about the future. So, can we combine the two technologies? We see that data is stored in the database, and predictions need to be based on past data. If we query future data through the existing data in the database, then it is
