小編給大家分享一下Mybatis應(yīng)用MySQL存儲過程查詢數(shù)據(jù)的示例分析,相信大部分人都還不怎么了解,因此分享這篇文章給大家參考一下,希望大家閱讀完這篇文章后大有收獲,下面讓我們一起去了解一下吧!
十載的雙塔網(wǎng)站建設(shè)經(jīng)驗,針對設(shè)計、前端、開發(fā)、售后、文案、推廣等六對一服務(wù),響應(yīng)快,48小時及時工作處理。成都全網(wǎng)營銷的優(yōu)勢是能夠根據(jù)用戶設(shè)備顯示端的尺寸不同,自動調(diào)整雙塔建站的顯示方式,使網(wǎng)站能夠適用不同顯示終端,在瀏覽器中調(diào)整網(wǎng)站的寬度,無論在任何一種瀏覽器上瀏覽網(wǎng)站,都能展現(xiàn)優(yōu)雅布局與設(shè)計,從而大程度地提升瀏覽體驗。創(chuàng)新互聯(lián)從事“雙塔網(wǎng)站設(shè)計”,“雙塔網(wǎng)站推廣”以來,每個客戶項目都認真落實執(zhí)行。
1.創(chuàng)建mysql存儲過程,這是個復(fù)雜查詢加上了判斷,比較復(fù)雜
CREATE PROCEDURE searchAllList ( IN tradingAreaId VARCHAR (50), IN categoryName VARCHAR (100), IN intelligenceSort TINYINT UNSIGNED, IN priceBegin DOUBLE, IN priceEnd DOUBLE, IN commodityName VARCHAR (200), IN flag TINYINT UNSIGNED ) BEGIN IF flag = 0 THEN SELECT B.user_business_id businessId, B.shop_name, B.total_score, B.shop_logo, B.average_consume, D.category_name, B.shop_address FROM user_business_commodity A LEFT JOIN user_business B ON B.user_business_id = A.user_business_id LEFT JOIN user_business_category C ON C.business_id = B.user_business_id LEFT JOIN service_category D ON D.category_id = C.category_one_id WHERE 1 = 1 AND IF ( categoryName IS NOT NULL AND LENGTH(TRIM(categoryName)) > 0, D.category_name = categoryName, 1 = 1 ) AND IF ( priceBegin != 0, B.average_consume >= priceBegin, 1 = 1 ) AND IF ( priceEnd != 0, B.average_consume <= priceEnd, 1 = 1 ) AND IF ( commodityName IS NOT NULL AND LENGTH(TRIM(commodityName)) > 0, A. NAME LIKE concat('%', commodityName, '%'), 1 = 1 ) AND B.is_delete = 0 AND B.shop_setup_state = 1 AND A.is_delete = 0 AND C.is_delete = 0 AND D.is_delete = 0 GROUP BY A.user_business_id ORDER BY CASE intelligenceSort WHEN 1 THEN 'B.total_order DESC' WHEN 2 THEN 'B.total_score DESC' WHEN 3 THEN 'B.create_time DESC' ELSE 'B.create_time ASC' END; ELSE SELECT B.user_business_id businessId, B.shop_name, B.total_score, B.shop_logo, B.average_consume, D.category_name, B.shop_address FROM user_business_commodity A LEFT JOIN user_business B ON B.user_business_id = A.user_business_id LEFT JOIN user_business_category C ON C.business_id = B.user_business_id LEFT JOIN service_category D ON D.category_id = C.category_two_id WHERE 1 = 1 AND IF ( categoryName IS NOT NULL AND LENGTH(TRIM(categoryName)) > 0, D.category_name = categoryName, 1 = 1 ) AND IF ( priceBegin != 0, B.average_consume >= priceBegin, 1 = 1 ) AND IF ( priceEnd != 0, B.average_consume <= priceEnd, 1 = 1 ) AND IF ( commodityName IS NOT NULL AND LENGTH(TRIM(commodityName)) > 0, A. NAME LIKE concat('%', commodityName, '%'), 1 = 1 ) AND B.is_delete = 0 AND B.shop_setup_state = 1 AND A.is_delete = 0 AND C.is_delete = 0 AND D.is_delete = 0 GROUP BY A.user_business_id ORDER BY CASE intelligenceSort WHEN 1 THEN 'B.total_order DESC' WHEN 2 THEN 'B.total_score DESC' WHEN 3 THEN 'B.create_time DESC' ELSE 'B.create_time ASC' END; END IF; END;
2.查看存儲過程是否創(chuàng)建成功:
show procedure status;
3.sqlMapper文件:
其他和直接調(diào)用sql語句一樣了
