今天在寫資料遷移的儲存過程發現總會多執行一條記錄修改後記錄如下：

DECLARE notfoundroute INT DEFAULT 0;

declare route_cursor CURSOR FOR  select uid,	uteamid,	iday,	ctitle,	ctrip,	ctraffic,	cdinner,	chotel,	cmemo,	uuserid,	dupdate,	istop,	cdepartcity,	carrivecity,	cboardtime,	cofftime,	iadddays,	clineno,	ccarriername,	usupplierid,	cport,	ctransit from t_team_route   where uTeamID = vuid ;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET notfoundroute = 1;
OPEN route_cursor;
flag_line2:LOOP

FETCH route_cursor into  vrouid,	vrouteamid,	vroiday,	vroctitle,	vroctrip,	vroctraffic,	vrocdinner,	vrochotel,	vrocmemo,	vrouuserid,	vrodupdate,	vroistop,	vrocdepartcity,	vrocarrivecity,	vrocboardtime,	vrocofftime,	vroiadddays,	vroclineno,	vroccarriername,	vrousupplierid,	vrocport,	vroctransit;
IF notfoundroute = 1 THEN LEAVE flag_line2; END IF;
IF notfoundroute =0 THEN  
insert into GW_ROUTE( OBJ_TYPE,	OBJ_ID,	IDAY,	TITLE,	DEPART_CITY,	ARRIVAL_CITY,	DEPART_TIME,	ARRIVAL_TIME,	CARRIER_NAME,	SITE,	NIGHT_DAYS,	SHIFT_NO,	TRIP,	TRAFFIC,	DINNER,	HOTEL,	INSTRUCTION,	STATUS,	CREATE_TIME,	UPDATE_TIME,	CREATOR,	OPERATOR)  
values ('O',offer_id,vroiDay,vrocTitle,vrocDepartCity,vrocarrivecity,vrocBoardTime,vrocOffTime,vrocCarrierName,vroiStop,vroiAddDays,vrocLineNo,vrocTrip,vroctraffic,vrocdinner,vrochotel,vrocmemo,'E',@timenow,@timenow,4,4);
END IF;
END LOOP;
CLOSE route_cursor;
 

主要是在遍歷遊標的時候要先FETCH 在判斷notfoundroute的值，這樣就不會多執行一條了。
