在SELECT子句中，使用了<include>标签引用了一个名为"dayColumns"的SQL片段，表示查询的列。在FROM子句中，使用了<include>标签引用了一个名为"dayJoins"的SQL片段，表示查询的表和关联条件。此外，还使用了${ew....

其中包含了删除、插入、更新和查询操作，分别用于删除商品、删除用户、查询所有商品、根据商品ID查询商品、根据用户账号查询用户、查询所有用户、插入用户和插入商品等操作。该 mapper 文件对应的命名空间为 ...

这段代码是 MyBatis 的 Mapper 文件，用于定义数据库操作的 SQL 语句。该 Mapper 定义了一些 SQL 语句，包括查询所有申请、按用户名查询申请、...这些 SQL 语句可以通过 MyBatis 框架调用执行，从而对数据库进行操作。

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="org.mybatis.example.BlogMapper"> <select id="selectStudentById" resultType="Student"> select * from s_student where id = #{id} </select> <select id="selectStudentByCId" resultType="Student"> select * from s_student where cid = #{cid} </select> <insert id="insertStudent" parameterType="Student" > insert into s_student(name,age,cid) values(#{name},#{age},#{cid}) </insert> <select id="selectStudentsByClassName" resultType="Student"> SELECT s.* FROM s_student s JOIN s_class c ON s.cid = c.id WHERE c.name = #{className} </select> <update id="updateStudent" parameterType="Student"> UPDATE s_student SET name = #{name}, age = #{age} WHERE id = #{id} </update> <delete id="deleteStudentById" parameterType="int"> DELETE FROM s_student WHERE id = #{id} </delete> </mapper>

resultType 属性指定了查询结果的返回类型，parameterType 属性指定了 SQL 语句的参数类型。具体来说，这个映射文件中包含了通过学生 id 和班级 id 查询学生信息、插入学生信息、通过班级名称查询学生信息、修改学生...

<select id="page" resultType="com.you.vo.YddAdvImgVO"> select ai.id id, ai.advimgpos advimgpos, ai.advimgsrc advimgsrc, ai.advimgdesc advimgdesc, ai.advimglink advimglink,ap.advposname advposname from ydd_advimg ai left join ydd_advpos ap on ai.advimgpos = ap.id <where> <if test="advimgdesc!=null"> advimgdesc = #{advimgdesc} </if> <if test="advimgpos!=null"> and advimgpos = #{advimgpos} </if> </where> </select>

这是一个使用 MyBatis 框架写的...其中，<if> 标签用于条件判断，根据传入的参数不同来动态生成不同的 SQL 语句，从而实现动态查询。如果你的问题是关于这个 SQL 语句的，我需要知道具体的问题是什么，才能帮你解答。

- <select> 标签定义了一个查询语句，id 属性指定了查询语句的唯一标识。 - parameterType 属性指定了传入查询语句的参数类型，这里是一个 Map 类型。 - resultType 属性指定了查询结果的返回类型，这里...

<select id="getProductByStatusWhenCalculatePage" resultMap="productResultMap"> SELECT p.id, p.user_id, p.goods_name, GROUP_CONCAT(i.url SEPARATOR ',') AS images FROM pms_product AS p LEFT JOIN pms_product_images AS i ON p.id = i.product_id WHERE p.status = #{status} GROUP BY p.id </select> <resultMap id="productResultMap" type="Product"> <id property="id" column="id"/> <result property="userId" column="user_id"/> <result property="goodsName" column="goods_name"/> <collection property="images" ofType="java.lang.String"> <result column="images" /> </collection> </resultMap> resulttype用Map实现，不要使用vo类或实体类

<select id="getPage" resultType="Student"> <include refid="getPageSQL"/> limit #{start}, #{pageSize} </select>

<include>标签用于引入之前定义的SQL片段，这里通过refid属性指定了要引入的SQL片段为getPageSQL，即前面提到的getPageSQL的定义。在引入SQL片段后，使用了limit关键字来限制查询结果的数量。#{start}...

<select id="queryUsersByNameAndAge" resultType="com.example.model.User"> SELECT * FROM users WHERE <if test="name != null and name != ''"> name = #{name} </if> <if test="age != 0"> <if test="name != null and name != ''"> AND </if> age = #{age} </if> </select>

这是一个基于MyBatis的查询语句，用于...查询语句的逻辑如下： - 如果传入的name参数不为空，则拼接name条件。 - 如果传入的age参数不为0，则拼接age条件。如果同时传入了name参数，则在name条件之后添加AND关键字。 ...

"sqiLog"的配置是一个Mybatis的<select>标签，在其中定义了一个名为"sqiLog"的SQL查询语句，使用了一个名为"appLog"的参数类型，并且指定了返回结果的类型也是"appLog"。在SQL查询语句中使用了一个<if>标签，用于...
