Mybatis应用mysql存储过程查询数据实例

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_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)) > 0,1 = 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：

<select id="searchAllList1" parameterMap="searchAllListMap" statementType="CALLABLE" resultType="com.dongjia168.platform.vo.erp.crm.BusinessShopResp"> 
    CALL searchAllList(#{tradingAreaId},#{categoryName},#{intelligenceSort},#{priceBegin},#{priceEnd},#{commodityName},#{flag}); 
  </select> 

<parameterMap id="searchAllListMap" type="com.dongjia168.platform.vo.erp.crm.BusinessShopReq"> 
    <parameter property="tradingAreaId" jdbcType="VARCHAR" mode="IN"/> 
    <parameter property="categoryName" jdbcType="VARCHAR" mode="IN"/> 
    <parameter property="intelligenceSort" jdbcType="INTEGER" mode="IN"/> 
    <parameter property="priceBegin" jdbcType="DOUBLE" mode="IN"/> 
    <parameter property="priceEnd" jdbcType="DOUBLE" mode="IN"/> 
    <parameter property="commodityName" jdbcType="VARCHAR" mode="IN"/> 
    <parameter property="flag" jdbcType="INTEGER" mode="IN"/> 
  </parameterMap> 

其他和直接调用sql语句一样了
