1、数据库链接

int cppDatebase::DatabaseConnect(sBit8 *uName,sBit8 *pWord,sBit8 *dbName)

{

dbHandle = mysql_init(NULL);

if(NULL == dbHandle )

{

cout<

return (-1);

}

if(NULL == mysql_real_connect(dbHandle ,"localhost",uName,pWord,dbName,0,NULL,0))

{

cout<

return (-1);

}

mysql_set_character_set(dbHandle ,"utf8");

return 0;

}

2、数据库插入——增

int cppDatebase::DatabaseInsert(const char *cmd)

{

if(NULL == cmd)

{

cout<

return (-1);

}

int ret = mysql_query(dbHandle,cmd);

if(ret !=0)

{

cout << "Database Insert Info: exist, I am updata." <

return (-1);

}

return 0;

}

3、数据库删除——删

int cppDatebase::DatabaseDelete(const char *cmd)

{

if(NULL == cmd)

{

cout<

return (-1);

}

int ret = mysql_query(dbHandle,cmd);

if(ret !=0)

{

cout << "Database Delete Info: not exist." <

return (-1);

}

return 0;

}

4、数据库更新——改

int cppDatebase::DatabaseUpdate(const char *cmd)

{

if(NULL == cmd)

{

cout<

return (-1);

}

int ret = mysql_query(dbHandle,cmd);

if(ret !=0)

{

cout << "Database Update Info: not exist, I am insert." <

return (-1);

}

return 0;

}

5、数据库查询——查

int cppDatebase::DatabaseQuery(char *cmd, char **row)

{

if(NULL == cmd || NULL == row)

{

cout<

return (-1);

}

mysql_real_query(dbHandle,cmd,strlen(cmd));

MYSQL_RES *result = mysql_store_result(dbHandle);

if(result != NULL)

{

int numLine = mysql_num_rows(result);

int numList = mysql_num_fields(result);

}

else

{

cout<

return (-1);

}

while((row = mysql_fetch_row(result)))

{

printf("%s, %s %s %s\n",row[0],row[1],row[2],row[3]);

}

mysql_free_result(result);

return 0;

}

6、数据库断开

int cppDatebase::DatabaseClose()

{

mysql_close(dbHandle);

return 0;

}
