1.创建mysql存储过程,这是个复杂查询加上了判断,比较复杂
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.查看存储过程是否创建成功:
show procedure status;
3.sqlMapper文件:
其他和直接调用sql语句一样了
