HomeDatabaseMysql TutorialMySQL5创建存储过程的示例

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

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。

Steps to add and delete fields to MySQL tablesSteps to add and delete fields to MySQL tablesApr 29, 2025 pm 04:15 PM

In MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.

How to analyze the execution plan of MySQL queryHow to analyze the execution plan of MySQL queryApr 29, 2025 pm 04:12 PM

Use the EXPLAIN command to analyze the execution plan of MySQL queries. 1. The EXPLAIN command displays the execution plan of the query to help find performance bottlenecks. 2. The execution plan includes fields such as id, select_type, table, type, possible_keys, key, key_len, ref, rows and Extra. 3.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
