使用方法：

int resultValue;

char* userId="1000";

       char insertQuery[22584];

//init mysql conection

MySqlInit();

//sprintf(insertQuery, "INSERT INTO `webcat_cloud`.`t_wechat_user` (`user_id`,`open_id`, `subscribe_flag`,`create_date`,`l_upd_date`) VALUES (‘367‘,‘adadfasdfs‘, ‘0‘,now(),now())");

//拼接sql语句

strcpy(insertQuery, "INSERT INTO `webcat_cloud`.`t_wechat_user` (`user_id`,`open_id`, `subscribe_flag`,`create_date`,`l_upd_date`) VALUES ( ‘");

strcat(insertQuery, lr_eval_string(userId)); //参数化数据

strcat(insertQuery, "‘, ‘");

strcat(insertQuery, lr_eval_string(openId)); //参数化数据

strcat(insertQuery, "‘,‘0‘,now(),now())");

strcat(insertQuery, ";");

lr_message(insertQuery);

//execute sql

lr_start_transaction("Insert");

resultValue=http://www.mamicode.com/InsertValue(insertQuery);

    if(resultValue != 0)

    {

        lr_end_transaction("Insert",LR_FAIL);

    }

    else

    {

        lr_end_transaction("Insert",LR_PASS);

userId ++;

    }

变量类型转换：

itoa(count,port,10);                                     //count转CHAR放入port变量

count = atoi(lr_eval_string("<rp>"));                        //取DAT文件中的端口号转化成整数型放到count变量中

变量类型转换：
itoa(count,port,10); //count转CHAR放入port变量
count = atoi(lr_eval_string("<rp>")); //取DAT文件中的端口号转化成整数型放到count变量中
