Mybatis语法笔记

1.条件查询
<sql id="queryColumn">
        id,
        name name
</sql>
    
<select id="findList" resultType="packageName">
        SELECT 
            <include refid="queryColumn"></include>
        FROM 
            T_TABLE A 
        WHERE 
            1 = 1
        <if test="name != null and name != '' ">
            AND (A.NAME like '%${name}' or A.NAME like '${name}%' or A.NAME like '%${name}%')
        </if>
        ORDER BY 
            A.CREATE_TIME DESC 
</select>

2.函数查询　
<select id="queryAreaData" resultType="packageName">
        SELECT 
　　　　　　A.ID code,
　　　　　　A.NAME name,
        　(SELECT group_concat(CONCAT('{"code":"',t.id,'",'),CONCAT('"name":"',t.NAME,'"}') SEPARATOR '/') FROM (SELECT b.PARENT_ID,b.id,b.NAME FROM ADS_ADDRESS b where b.level_type =3  GROUP BY b.id,b.NAME)t where t.PARENT_ID=a.id) chird 
        FROM 
　　　　　　ADS_ADDRESS A  
        WHERE 
　　　　　　A.LEVEL_TYPE =2
        GROUP BY 
　　　　　　A.ID,A.NAME
</select>

3.循环查询
<select id="list" resultType="packageName">
        SELECT 
            ID id,
            NAME name
        FROM 
           T_TABLE A 
        WHERE 
　　　　　　 A.ID IN
        　 <foreach item="item" index="index" collection="array" open="(" separator="," close=")">  
           　　#{item}  
           </foreach>
</select>

4.循环插入　
<insert id="insertList">
        INSERT INTO T_TABLE(
            ID, 
            NAME
        )VALUES
        <foreach collection="list" item="item" index="index" open="(" separator="),(" close=")">
            #{item.id},
            #{item.name}
         </foreach>
</insert>

5.Msp参数判断查询

　　Map<String, Integer> map = new HashMap<String, Integer>();
　　map.put("pageIndex", pageIndex);
　　map.put("pageSize", pageSize);

<select id="queryBouncePage" parameterType="java.util.Map" resultType="JavaBean">

        SELECT 
            * 
        FROM 
            T_TABLE
        WHERE ID IN
        <foreach collection="ids" item="item" index="index" open="(" separator="," close=")">  
            #{item}  
        </foreach>
        <if test="_parameter.containsKey('pageIndex') and _parameter.containsKey('pageSize')">
            limit #{pageIndex}, #{pageSize}
        </if>
</select>

6.属性为对象查询

public class StoreInfoDto {
    private int id;
    private List<StoreImgDto> imgDtos;// 店铺图片
    private List<StoreLabelDto> labelDtos;// 店铺标签
    private List<StoreReviewDto> reviewDtos;// 店铺评论
    private List<StoreErrorDto> errorDtos;// 顾客报错信息
    private ProvinceDto provinceDto;// 省
    private CityDto cityDto;// 市
    private AreaDto areaDto;// 区
    private String merchantNo;// 商户编号
    private String code;// 编码CODE
    private String name;// 店名
    private String alias;// 店别名
    private String address;// 店铺地址
    private String addressDetail;// 店铺地址详情

    .......

    get、set.......
}
