Mybatis應用mysql存儲過程查詢數據的示例分析

小編給大家分享一下Mybatis應用mysql存儲過程查詢數據的示例分析，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！

1.創建mysql存儲過程，這是個復雜查詢加上了判斷，比較復雜

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>

其他和直接調用sql語句一樣了
