C++对Mysql数据库的访问查询(基于Mysql5.0的API,vs2010中操作
右击项目名称-属性,配置引用Mysql数据库的库目录,见图: 添加附加包目录为C:\Program Files\MySQL\MySQL Server 5.0\include 拷贝libmySQL.dll(C:\Program Files\MySQL\MySQL Server 5.0\bin)和libmysql.lib(C:\Program Files\MySQL\MySQL Server 5.0\lib
右击项目名称->属性,配置引用Mysql数据库的库目录,见图:
添加附加包目录为C:\Program Files\MySQL\MySQL Server 5.0\include
拷贝libmySQL.dll(C:\Program Files\MySQL\MySQL Server 5.0\bin)和libmysql.lib(C:\Program Files\MySQL\MySQL Server 5.0\lib\opt)到运行目录下,如调试时放在Debug下
然后代码如下
#include "windows.h" #include "winsock.h" #include "stdio.h" #include "mysql.h" #pragma comment(lib,"libmySQL.lib") #include <iostream> using namespace std; int main() { char dbuser[30]="root"; char dbpasswd[30]="password"; char dbip[30]="localhost"; char dbname[50]="temperature"; MYSQL *con=mysql_init((MYSQL *)0); if (con!=NULL&&mysql_real_connect(con,dbip,dbuser,dbpasswd,dbname,3306,NULL,0)) { printf("SUCCESSFULLY."); mysql_query(con,"select * from temperature"); MYSQL_RES *result=mysql_store_result(con); unsigned int fieldcount=mysql_num_fields(result); coutname <p><br> </p> </iostream>

Using the chrono library in C can allow you to control time and time intervals more accurately. Let's explore the charm of this library. C's chrono library is part of the standard library, which provides a modern way to deal with time and time intervals. For programmers who have suffered from time.h and ctime, chrono is undoubtedly a boon. It not only improves the readability and maintainability of the code, but also provides higher accuracy and flexibility. Let's start with the basics. The chrono library mainly includes the following key components: std::chrono::system_clock: represents the system clock, used to obtain the current time. std::chron

MySQL and phpMyAdmin can be effectively managed through the following steps: 1. Create and delete database: Just click in phpMyAdmin to complete. 2. Manage tables: You can create tables, modify structures, and add indexes. 3. Data operation: Supports inserting, updating, deleting data and executing SQL queries. 4. Import and export data: Supports SQL, CSV, XML and other formats. 5. Optimization and monitoring: Use the OPTIMIZETABLE command to optimize tables and use query analyzers and monitoring tools to solve performance problems.

DMA in C refers to DirectMemoryAccess, a direct memory access technology, allowing hardware devices to directly transmit data to memory without CPU intervention. 1) DMA operation is highly dependent on hardware devices and drivers, and the implementation method varies from system to system. 2) Direct access to memory may bring security risks, and the correctness and security of the code must be ensured. 3) DMA can improve performance, but improper use may lead to degradation of system performance. Through practice and learning, we can master the skills of using DMA and maximize its effectiveness in scenarios such as high-speed data transmission and real-time signal processing.

ABI compatibility in C refers to whether binary code generated by different compilers or versions can be compatible without recompilation. 1. Function calling conventions, 2. Name modification, 3. Virtual function table layout, 4. Structure and class layout are the main aspects involved.

Handling high DPI display in C can be achieved through the following steps: 1) Understand DPI and scaling, use the operating system API to obtain DPI information and adjust the graphics output; 2) Handle cross-platform compatibility, use cross-platform graphics libraries such as SDL or Qt; 3) Perform performance optimization, improve performance through cache, hardware acceleration, and dynamic adjustment of the details level; 4) Solve common problems, such as blurred text and interface elements are too small, and solve by correctly applying DPI scaling.

C performs well in real-time operating system (RTOS) programming, providing efficient execution efficiency and precise time management. 1) C Meet the needs of RTOS through direct operation of hardware resources and efficient memory management. 2) Using object-oriented features, C can design a flexible task scheduling system. 3) C supports efficient interrupt processing, but dynamic memory allocation and exception processing must be avoided to ensure real-time. 4) Template programming and inline functions help in performance optimization. 5) In practical applications, C can be used to implement an efficient logging system.

C code optimization can be achieved through the following strategies: 1. Manually manage memory for optimization use; 2. Write code that complies with compiler optimization rules; 3. Select appropriate algorithms and data structures; 4. Use inline functions to reduce call overhead; 5. Apply template metaprogramming to optimize at compile time; 6. Avoid unnecessary copying, use moving semantics and reference parameters; 7. Use const correctly to help compiler optimization; 8. Select appropriate data structures, such as std::vector.

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.
