Linux编程 - 使用C在mysql中插入数据

1. 代码编写

   #include <stdlib.h> 
  
#include <stdio.h> 
  
#include  
  " 
  mysql.h 
  " 
  
 
  
 
  int main( 
  int argc,  
  char *argv[])  
  
{ 
  
    MYSQL my_connection; 
  
     
  int res; 
  
    mysql_init(&my_connection); 
  
     
  
     
  if (mysql_real_connect(&my_connection,  
  " 
  localhost 
  ",  
  " 
  root 
  ",  
  " 
  mysql 
  ",  
  " 
  mysql 
  ",  
  0, NULL,  
  0))  
  
    { 
  
        printf( 
  " 
  Connection success\n 
  "); 
  
        res = mysql_query(&my_connection,  
  " 
  INSERT INTO children(fname, age) VALUES('david', 8) 
  "); 
  
         
  
         
  if (!res)  
  
        { 
  
            printf( 
  " 
  Inserted %lu rows\n 
  ", (unsigned  
  long)mysql_affected_rows(&my_connection)); 
  
        }  
  
         
  else  
  
        { 
  
            fprintf(stderr,  
  " 
  Insert error %d: %s\n 
  ", mysql_errno(&my_connection), 
  
            mysql_error(&my_connection)); 
  
        } 
  
         
  
        mysql_close(&my_connection); 
  
    }  
  
     
  else  
  
    { 
  
        fprintf(stderr,  
  " 
  Connection failed\n 
  "); 
  
         
  if (mysql_errno(&my_connection))  
  
        { 
  
            fprintf(stderr,  
  " 
  Connection error %d: %s\n 
  ", 
  
            mysql_errno(&my_connection), mysql_error(&my_connection)); 
  
        } 
  
    } 
  
         
  
     
  return EXIT_SUCCESS; 
  
}
