c语言连接mysql数据库的实现方法

我这里也有一份网上找到的：/201205/other/C_link_mySql51.rar
C连接MySql5.1所需文件.rar
附带一个不错的例子：

#include  
#include  
#include  
#include  
#include  
#pragma comment(lib,"libmysql") 
 
#define HOST "localhost" 
#define USERNAME "root" 
#define PASSWORD "123456" 
#define DATAbase "test" 
 
void exe_sql(char* sql) { 
MYSQL my_connection;  
int res;  
 
mysql_init(&my_connection); 
 
if (mysql_real_connect(&my_connection, HOST, USERNAME, PASSWORD, 
DATAbase, 0, NULL, CLIENT_FOUND_ROWS)) { 
printf("数据库执行exe_sql连接成功！n"); 
 
mysql_query(&my_connection, "set names utf8"); 
 
res = mysql_query(&my_connection, sql); 
if (res) { 
printf("Error： mysql_query !n"); 
 
mysql_close(&my_connection); 
} else { 
 
printf("%d 行受到影响！n", 
mysql_affected_rows(&my_connection)); 
 
mysql_close(&my_connection); 
} 
} else { 
 
printf("数据库执行exe_sql连接失败！n"); 
} 
} 
 
void query_sql(char* sql) { 
MYSQL my_connection;  
int res;  
MYSQL_RES *res_ptr;  
MYSQL_FIELD *field;  
MYSQL_ROW result_row;  
int row, column;  
int i, j;  
 
mysql_init(&my_connection); 
 
if (mysql_real_connect(&my_connection, HOST, USERNAME, PASSWORD, 
DATAbase, 0, NULL, CLIENT_FOUND_ROWS)) { 
printf("数据库查询query_sql连接成功！n"); 
 
mysql_query(&my_connection, "set names utf8"); 
*下面这句话就是用mysql_query函数来执行我们刚刚传入的sql語句， 
这会返回一个int值，如果为0，证明語句执行成功*/ 
res = mysql_query(&my_connection, sql); 
if (res) {  
printf("Error： mysql_query !n"); 
 
mysql_close(&my_connection); 
} else {  
 
res_ptr = mysql_store_result(&my_connection); 
 
if (res_ptr) { 
 
column = mysql_num_fields(res_ptr); 
row = mysql_num_rows(res_ptr) + 1; 
printf("查询到 %lu 行 n", row); 
 
for (i = 0; field = mysql_fetch_field(res_ptr); i++) 
printf("%st", field->name); 
printf("n"); 
 
for (i = 1; i < row; i++) { 
result_row = mysql_fetch_row(res_ptr); 
for (j = 0; j < column; j++) 
printf("%st", result_row[j]); 
printf("n"); 
} 
} 
 
mysql_close(&my_connection); 
} 
} 
} 
int main(int argc, char *argv[]) { 
 
char *query; 
char *exe = "insert into student values('lala','hahhahah!');"; 
exe_sql(exe); 
*测试下查询*/ 
query="select * from student;"; 
query_sql(query); 
return 0; 
}
