mybatis time interval comparison

mybatis time interval comparison

 

jdbcType=TIMESTAMP, jdbcType=DATE determines the format of the time
Some functions are not available in different versions of mysql
Note that the date type is passed in   < if test ="empId != null and empId != '' " >

AND o.EMP_ID = ${empId}
</if>
You can't have a comparison with strings like and empId != '', unless you pass in a type designed for string

Go directly to the code, the Date type used by the database at this time: (ie: database type date, incoming is string)

　　　　<if test="minCreateTime != null and  minCreateTime != ''">
            <![CDATA[ and g.create_time >= to_date(#{minCreateTime,jdbcType=DATE},'yyyy-MM-dd hh24:mi:ss')]]>
        </if>
        <if test="maxCreateTime != null and  maxCreateTime != ''">
            <![CDATA[ and g.create_time <= to_date(#{maxCreateTime,jdbcType=DATE},'yyyy-MM-dd hh24:mi:ss')]]>
        </if>

If it is a string type, it can also be compared directly, as follows: (date is passed in, any type of database)

　　　　　　　<if test="createTime != null">
                AND CREATE_TIME = CONCAT(CONCAT('%', #{createTime,jdbcType=DATE}), '%')
            </if>
            <if test="updateTime != null">
                AND UPDATE_TIME = CONCAT(CONCAT('%', #{updateTime,jdbcType=DATE}), '%')
            </if>

 

 

<if test="minCreateTime != null and  minCreateTime != ''">
            <![CDATA[ and g.create_time >= to_date(#{minCreateTime,jdbcType=DATE},'yyyy-MM-dd hh24:mi:ss')]]>
        </if>
        <if test="maxCreateTime != null and  maxCreateTime != ''">
            <![CDATA[ and g.create_time <= to_date(#{maxCreateTime,jdbcType=DATE},'yyyy-MM-dd hh24:mi:ss')]]>
        </if>
