Mybatis的分支选择和In循环

Mybatis的分支选择：

<choose>
   <when test="patientNo != null and patientNo != ''">
      and ipi.patient_no = #{patientNo}
   </when>
   <otherwise>
      <if test="patientName != null and patientName != ''">
         and ipi.patient_name like CONCAT('%',#{patientName},'%')
      </if>
      <trim prefix="where" prefixOverrides="and">
         <if test="printTimeBegin != null and printTimeBegin != ''">
            and mrm.print_time >= #{printTimeBegin}
         </if>
         <if test="printTimeEnd != null and printTimeEnd != ''">
            and mrm.print_time  &lt;=  #{printTimeEnd}
         </if>
      </trim>
   </otherwise>
</choose>

循环In：

<if test='depts!=null and depts.size()>0'>
   and ioh.department_id IN
   <foreach item="item" index="index" collection="depts" open="(" separator="," close=")">
      #{item}
   </foreach>
</if>
