Question

Я установил переменную, прежде чем использовать dplookup для выбора результата, параметр:

mc.setProperty("year","2019");
mc.setProperty("month","11");
mc.setProperty("date","7");

dblookup равен

<dblookup>
    <connection>
        <pool>
            <password>XXXX</password>
            <driver>com.mysql.jdbc.Driver</driver>
            <url>jdbc:mysql://XXXX</url>
            <user>XXXX</user>
        </pool>
    </connection>
    <statement>
        <sql><![CDATA[
            SELECT IFNULL(max(ID_),0) as MAX_ID_ FROM KETTLE WHERE YEAR(FROM_UNIXTIME(DETECTION_TIME_ / 1000)) = ? AND MONTH(FROM_UNIXTIME(DETECTION_TIME_ / 1000)) = ? AND DAYOFMONTH(FROM_UNIXTIME(DETECTION_TIME_ / 1000)) = ?;
        ]]></sql>
        <parameter expression="get-property('year')" type="VARCHAR"/>
        <parameter expression="get-property('month')" type="VARCHAR"/>
        <parameter expression="get-property('date')" type="VARCHAR"/>
        <result column="MAX_ID_" name="MAX_ID_"/>
    </statement>
</dblookup>

Иногда это работает, иногда нетработа
