??初學使用用C語言操作MYSQL，寫了個小例子，帖上來獻丟人一下，呵呵。

? ? ?程序很簡單，先連接數據庫，然后向class1表中插入一條數據，最后獲取并輸出整個class1表的內容。

上代碼：

[cpp]?view plain?copy

//test.c??

//gcc?test.c?-o?test?-lmysqlclient??

#include?<stdio.h>??

#include?<stdlib.h>??

#include?<mysql/mysql.h>??

??

//發生錯誤時，輸出錯誤信息，關閉連接，退出程序??

void?error_quit(const?char?*str,?MYSQL?*connection)??

{??

????fprintf(stderr,?"%s?:?%d:?%s\n",??

????????str,?mysql_errno(connection),??

????????mysql_error(connection));??

????if(?connection?!=?NULL?)??

????????mysql_close(connection);??

????exit(1);??

}??

??

int?main(int?argc,?char?*argv[])???

{??

????MYSQL?*my_con?=?malloc(?sizeof(MYSQL)?);??

????MYSQL_RES?*my_res;??

????MYSQL_FIELD?*my_field;??

????MYSQL_ROW?my_row;??

????int?rows,?i;??

????int?res;??

??

????//連接數據庫??

????mysql_init(my_con);???

????my_con?=?mysql_real_connect(my_con,?"localhost",?"test",?"aaaaaaa",??

????????"test1",?0,?NULL,?CLIENT_FOUND_ROWS);??

????if(?NULL?==?my_con?)???

????????error_quit("Connection?fail",?my_con);??

????printf("Connection?success\n");??

??

????//向數據庫中插入一條記錄??

????res?=?mysql_query(my_con,???

????????"insert?into?class1(name,?age,?birthday)?value('abc',?52,?NOW());");??

????if(?res?!=?0?)???

????????error_quit("Insert?fail",?my_con);??

????//返回的是表中被影響的行數??

????res?=?mysql_affected_rows(my_con);??

????printf("Inserted?%d?rows\n",?res);??

??

????//獲取整個表的內容??

????res?=?mysql_query(my_con,?"select?*?from?class1;");??

????if(?res?!=?0?)??

????????error_quit("Select?fail",?my_con);??

????my_res?=?mysql_store_result(my_con);??

????if(?NULL?==?my_res?)??

????????error_quit("Get?result?fail",?my_con);??

??

????//獲取表的列數??

????rows?=?mysql_num_fields(my_res);??

????//獲取并輸出表頭??

????my_field?=?mysql_fetch_fields(my_res);??

????for(i=0;?i<rows;?i++)??

????????printf("%s\t",?my_field[i].name);??

????printf("\n-------------------------------------\n");??

??

????//輸出整個表的內容??

????while(?1?)??

????{??

????????my_row?=?mysql_fetch_row(my_res);??

????????if(?NULL?==?my_row?)??

????????????break;??

????????for(i=0;?i<rows;?i++)??

????????{??

????????????if(?my_row[i]?==?NULL?)??

????????????????printf("NULL\t");??

????????????else??

????????????????printf("%s\t",?(char*)my_row[i]);??

????????}??

????????printf("\n");??

????}??

??

????//釋放空間，關閉連接??

????mysql_free_result(my_res);??

????mysql_close(my_con);??

????free(my_con);??

??

????return?0;??

}??

運行結果：

[plain]?view plain?copy

Connection?success??

Inserted?1?rows??

id??name????age?birthday??

-------------------------------------??
