项目中经常会用到的sql语句有：

一、insert语句

<!--保存用户信息-->
<insert id="save">
        insert into mainsite_product_message
        <trim prefix="(" suffix=")" suffixOverrides=",">
            <if test="customerName != null and customerName != ''">
                customer_name,
            </if>
            <if test="customerPhone != null and customerPhone != ''">
                customer_phone,
            </if>
            <if test="customerEmail != null and customerEmail != ''">
                customer_email,
            </if>
            <if test="createTime != null">

            </if>
            <if test="customerStatus != null and customerStatus != ''">
                customer_status,
            </if>
        </trim>
        <trim prefix="values (" suffix=")" suffixOverrides=",">
            <if test="customerName != null and customerName != ''">
                #{customerName},
            </if>
            <if test="customerPhone != null and customerPhone != ''">
                #{customerPhone},
            </if>
            <if test="customerEmail != null and customerEmail != ''">
                #{customerEmail},
            </if>
            <if test="createTime != null">
                #{createTime},
            </if>
            <if test="customerStatus != null and customerStatus != ''">
                #{customerStatus},
            </if>
        </trim>
    </insert>

    <!--修改用户信息-->
    <update id="update">

    </update>

    <!--批量更改客户状态-->
    <update id="updateStatus">
        update mainsite_product_message set customer_status = 1 where id in
        <foreach collection="array" item="id" open="(" separator="," close=")" index="index">
            #{id}
        </foreach>
    </update>

    <!--根据主键删除留言，物理删除-->
    <delete id="deleteByPrimaryKey">
        delete from mainsite_product_message where id = #{id}
    </delete>

    <!--查询留言列表-->
    <select id="selectByCondition"
            resultType="com.uiotsoft.mainsite.module.productmessage.entity.ProductMessage">
        select
        id as id,
        site_id as siteId,
        site_name as siteName,
        customer_name as customerName,
        customer_phone as customerPhone,
        customer_email as customerEmail,
        product_want as productWant,
        create_time as createTime,
        customer_status as customerStatus,
        search_keyword as searchKeyword
        from mainsite_product_message
        <trim prefix="WHERE (" suffix=")" prefixOverrides="AND|OR">
            <if test="customerName != null and customerName != ''">
                customer_name like CONCAT('%', #{customerName}, '%')
            </if>
            <if test="customerPhone != null and customerPhone != ''">
                and customer_phone = #{customerPhone}
            </if>
            <if test="createTime != null">
                and create_time = #{createTime}
            </if>
            <if test="customerEmail != null and customerEmail != ''">

            </if>
        </trim>
        ORDER BY create_time DESC
    </select>

 <trim><choose><when></when><otherwise></otherwise></choose></trim>

二、select查询语句

<select id="selectByContentListBySiteIdAndCategoryIds"   resultType="java.util.Map">
        SELECT
        c.*,
        m.*,
        u.avatar avatar,
        u.username username
        FROM
        site_model_content c LEFT JOIN  site_model_${tableName}  m
        ON
        c.content_id = m.content_id
        LEFT JOIN
        t_sys_user u ON u.user_id = c.user_id
        <trim prefix="WHERE ("  suffix=")" prefixOverrides="AND|OR">
            c.status=1
            <if test="siteId!=null">
               AND  c.site_id = #{siteId}
            </if>
            <if test="categoryIds!=null">
               AND
                c.category_id in
                 <foreach item="item" index="index" collection="categoryIds" open="(" separator="," close=")">
                   #{item}
                 </foreach>
            </if>
            <if test='isRecommend!=null and isRecommend==1'>
                AND
                c.recommend = 1
            </if>
            <if test='whereParam!=null and valueParam!=null'>
                AND  m.${whereParam} = #{valueParam}
            </if>
            <if test='isPic!=null and isPic==1'>
                AND
                c.thumb!=''
            </if>
            <if test='isPic!=null and isPic==0'>
                AND
                c.thumb=''
            </if>
            <if test='siteType!=null'>
                AND
                c.site_type like CONCAT('%', #{siteType}, '%')
            </if>

        </trim>

        <choose>
            <when test="orderBy==1">
                order by c.content_id
            </when>
            <when test="orderBy==2">
                order by c.inputdate DESC
            </when>
            <when test="orderBy==3">
                order by c.inputdate
            </when>
            <when test="orderBy==4">
                order by c.updatedate DESC
            </when>
            <when test="orderBy==5">
                order by c.updatedate
            </when>
            <when test="isHot==1">
                order by c.view_num DESC
            </when>
            <otherwise>
                order by c.content_id DESC
            </otherwise>
        </choose>
    </select>

三、批量添加

<!-- 批量添加 -->
    <insert id="insertMore" useGeneratedKeys="true" keyProperty="siteId">
        INSERT INTO
            t_cms_site(
            site_name,
            `domain`,
            template,
            is_mobile,
            mobile_tpl,
            status
            )
            values
            <foreach item="item" collection="list" separator=",">
                (#{item.siteName},#{item.domain},#{item.template},
                #{item.isMobile},#{item.mobileTpl},#{item.status})
            </foreach>
    </insert>

四、与时间比较相关的

SELECT
        count(*)
        FROM
        crm_contract
        <where> isDel = 0
            <if test="departmentId != null and departmentId != null">

            </if>

            </if>
            <if test="director != null and director != ''">
                and director like CONCAT("%",#{director},"%")
            </if>
            <if test="signUser != null and signUser != ''">
                and signUser like CONCAT("%",#{signUser},"%")
            </if>
            <if test="startDate != null">
                <![CDATA[ and DATE_FORMAT(endDate,"%Y-%m-%d")  >= DATE_FORMAT(#{startDate},"%Y-%m-%d") ]]>

            </if>
        </where>

        select
        c.*
        from crm_contract c left join crm_customer_info i on c.customerId =
        i.customerId
        <where>
            c.isDel = 0
            <if test="startDate != null and startDate != ''">
                and c.endDate &gt;= #{startDate}
            </if>
            <if test="endDate != null and endDate != ''">
                and c.endDate &lt;= #{endDate}
