mysql中between...and..的使用,及时间范围的查询

      在mysql应用中,以范围进行查询的很多是以时间范围作为条件进行范围查询的,时间范围查询有

很多种写法,首先总结一下between....and...的使用方法:

<select id="conCurrentCount" parameterType="map" resultType="int">
        SELECT COUNT(*) FROM tbl_report_info
        <where>
            ActionTime BETWEEN #{startTime} AND #{endTime}
        </where>
    </select>

讲解:

SELECT * FROM tbl_student_info WHERE `height` between 1113 and 1122     

等同于:
SELECT
* FROM tbl_student_info WHERE `height` >= 1113 and `height` <= 1122
    SELECT * FROM tbl_student_info WHERE `createDate` between '20170101020304' and '20180101020304'    
        等同于:
    SELECT * FROM tbl_student_info WHERE `createDate` >= '20170101020304' and `createDate` <= '20180101020304'    

另外一种时间范围查询的方法如下:分别设定开始时间和结束时间:

<if test="endTime!=null and !&quot;&quot;.equals(endTime.trim())">
            AND m.endTime &lt; #{endTime}
        </if>
           <if test="startTime!=null  and !&quot;&quot;.equals(startTime.trim())">
            AND m.startTime &gt; #{startTime}
        </if>
