Ibatis sql书写经验

1 resultMap写在SQL之前

2 重复使用sql的方法：

<sql id="sql_selectHoliday ">
        select .....deleted  from t_holiday
    </sql>
   
    <select id="selectHolidays" resultMap="holidayResultMap">
        <include refid="sql_selectHoliday "></include>
         where deleted!=1
    </select>

3 比较日期的写法

<select id="selectHolidaysBetweenDates" resultMap="holidayResultMap">
        <include refid="sql_selectHoliday"></include>
        where deleted!=1 and
        <![CDATA[
        start_time <= to_date(#date1#,'yyyy-MM-dd HH24:MI:SS' ) and end_time >= to_date(#date2#,'yyyy-MM-dd HH24:MI:SS')
        ]]>
    </select>
