我正在使用db方法在MVC5中使用Entity Framework.我使用Mysql作為數(shù)據(jù)庫.我創(chuàng)建了一個(gè)過程,當(dāng)Mysql中的Call Procedure它符合我的期望時(shí).但是當(dāng)我在MVC中使用過程時(shí),它每次返回0.

存儲過程

CREATE PROCEDURE `checkSeasonAvailability`(

IN paramSeasonId INT,

IN paramHotelId INT,

IN paramStartDate varchar(20),

IN paramEndDate varchar(20)

)

BEGIN

DECLARE _startDate,_endDate DATETIME;

DECLARE _hotelseasonID BIGINT(20);

DECLARE _count,_rowCount,_dateDiff INT;

DECLARE _index INT DEFAULT 1;

DECLARE i INT DEFAULT 0;

DECLARE cursorSeasonList CURSOR FOR SELECT `hotel_season_id`,`start_date`,`end_date`

FROM hotel_season_link

WHERE hotel_id = paramHotelId &&

season_id = paramSeasonId &&

active = TRUE;

OPEN cursorSeasonList;

SET _rowCount=FOUND_ROWS();

SET _count=_rowCount;

IF(_rowCount>0) THEN

Proc:WHILE _index <= _rowCount DO

FETCH cursorSeasonList INTO _hotelseasonID,_startDate,_endDate;

SET _dateDiff=datediff(paramEndDate,paramStartDate);

SET i=0;

WHILE i <= _dateDiff DO

SELECT COUNT(*) FROM hotel_season_link

WHERE

adddate(paramStartDate,i) BETWEEN _startDate AND _endDate INTO _count;

IF(_count>0) THEN

SELECT 1;

LEAVE Proc;

END IF;

SET i=i+1;

END WHILE;

SET _index=_index+1;

END WHILE;

END IF;

END

CALL checkSeasonAvailability(1,3,'2014-12-26 00:00:00','2014-12-31 00:00:00');//call in mysql

調(diào)節(jié)器

String format = "yyyy-MM-dd hh:mm:ss";

var status = db.checkSeasonAvailability(seasonId, hotelId, startDate.ToString(format), endDate.ToString(format));

當(dāng)我調(diào)試我的代碼時(shí),我發(fā)現(xiàn)所有必需的參數(shù)發(fā)送成功,但我沒有得到返回值.

如果我的代碼有任何問題,請建議我.

總結(jié)
