操作系统:Linux Fedora 11开发环境:Eclipse,CDT,MySQL5.1.32(头文件使用MySQL5.1.35版本)准备工作:1、查看Linux中安装的MySQL
操作系统:Linux Fedora 11
开发环境:Eclipse,CDT,MySQL5.1.32(头文件使用MySQL5.1.35版本)
准备工作:
1、查看Linux中安装的MySQL版本,使用以下命令:
$rpm -qa mysql
2、查看/usr/include中是否有mysql文件夹以及其文件夹下的头文件*.h,执行以下命令:
$cd /usr/include/mysql
a.如果已经存在此文件夹,继续输入以下命令:
$ls -l|more
如果没有mysql.h mysql_version.h mysql_com.h等等,则说明缺少基本的开发头文件,则需要下载MySQL源程序,请到下载最新的MySQL源程序是mysql-5.1.35.zip;
b.如果以上命令执行后提示没有此目录或者文件夹,则需要在/user/include/目录下创建mysql目录,执行以下命令:
$sudo mkdir /usr/include/mysql
将mysql-5.1.35.zip解压到你的工作目录中如:/home/test/database/mysql/
执行以下命令,切换到以下目录中:
$cd /home/test/database/mysql/mysql-5.1.35
然后在此以上目录中执行以下命令:
$./configure
等待命令执行成功后,,执行以下命令:
$make
等待命令执行成功后,执行以下命令:
$sudo cp -r include/ /usr/include/mysql/
将头文件*.h拷贝到/usr/include/mysql/include目录中
3、创建一个项目以及设置改项目的编译以及运行环境
在Eclipse中创建一个项目MySQLConn
创建一个头文件MySQLConn.h,代码如下:
/*
* MySQLConn.h
*
* Created on: Jun 11, 2009
* Author: zhanglei
*/
#ifndef MYSQLCONN_H_
#define MYSQLCONN_H_
int TestMySQLConn();
#endif /* MYSQLCONN_H_ */
创建一个程序文件MySQLConn.c,代码如下:
/*
* MySQLConn.c
*
* Created on: Jun 11, 2009
* Author: zhanglei
*/
#include
#include
#include
#include
#include "MySQLConn.h"
int main(int agrc, char* argv[])
{
printf("MySQL Connection Test...");
return TestMySQLConn();
}
int TestMySQLConn()
{
MYSQL *pConn;
//MYSQL_RES *pRes;
//MYSQL_ROW my_conn;
pConn = mysql_init(NULL);
if(NULL == pConn)
{
printf("mysql_init failed!");
return EXIT_FAILURE;
}
pConn = mysql_real_connect(pConn, "127.0.0.1", "root", "123", "test", 3306, NULL, 0);
if(NULL == pConn)
{
printf("Connection failed!");
}
else
{
printf("Connection succeed!");
}
mysql_close(pConn);
return EXIT_SUCCESS;
}

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

MySQL is worth learning because it is a powerful open source database management system suitable for data storage, management and analysis. 1) MySQL is a relational database that uses SQL to operate data and is suitable for structured data management. 2) The SQL language is the key to interacting with MySQL and supports CRUD operations. 3) The working principle of MySQL includes client/server architecture, storage engine and query optimizer. 4) Basic usage includes creating databases and tables, and advanced usage involves joining tables using JOIN. 5) Common errors include syntax errors and permission issues, and debugging skills include checking syntax and using EXPLAIN commands. 6) Performance optimization involves the use of indexes, optimization of SQL statements and regular maintenance of databases.

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA
