java - passing empty field as parameter in jasper ireport -


the query 

select * db_accessadmin.customersummary   (accountnumber = $p{accountno} or $p{accountno}='') , (ppusermobile = $p{mobileno} or $p{mobileno}='') , ( ppuserstaticid = $p{customerid} or $p{customerid} = '') , (cast(requestdate date) between (cast($p{fromdate} date)) , (cast($p{todate} date)))

the aim generate report in jasper depending on values of parameters. when parameters 'fromdate' , 'todate' empty , query should pull out entire rows in db. how can modify query accepts null values 'fromdate' , 'todate'.

xml file

<jasperreport xmlns="http://jasperreports.sourceforge.net/jasperreports"     xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:schemalocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" name="customersummary2" language="groovy" pagewidth="595" pageheight="842" columnwidth="555" leftmargin="20" rightmargin="20" topmargin="20" bottommargin="20" uuid="d23efc9c-641e-4e8a-bb9e-25673ee5c713"> <property name="ireport.zoom" value="1.610510000000001"/> <property name="ireport.x" value="0"/> <property name="ireport.y" value="0"/> <parameter name="accountno" class="java.lang.string"/> <parameter name="mobileno" class="java.lang.string"/> <parameter name="customerid" class="java.lang.string"/> <parameter name="fromdate" class="java.util.date">     <defaultvalueexpression><![cdata[new date()]]></defaultvalueexpression> </parameter> <parameter name="todate" class="java.util.date">     <defaultvalueexpression><![cdata[$p{fromdate}+7]]></defaultvalueexpression> </parameter> <querystring>     <![cdata[select * db_accessadmin.customersummary (accountnumber =         $p{accountno} or $p{accountno}='')  , (ppusermobile = $p{mobileno} or $p{mobileno}='')  , ( ppuserstaticid = $p{customerid} or $p{customerid} = '')  , (cast(requestdate date) between (cast($p{fromdate} date)) , (cast($p{todate} date)))]]> </querystring>

this issue occurs when design report in jasper ireport. once deploy in server, issue resolved. server accepts null values.

Java sticky instances of class com.mysql.jdbc.Field aggregating -

i noticed (via jmap+jhat) app leaking storing many instances com.mysql.jdbc.field  class - double checked code make sure closing preparedstatements, find few missing didn't change outcome. - preparedstatement created , closed right away - several others created @ start , reused many times - using org.apache.tomcat.jdbc.pool.datasource connection pool what can cause type of behavior? are closing of preparedstatements / result sets using: preparedstatement stmt (possible assignment here); try { // work prepared statement resultset rs; try { while (rs.next()) ... // process results } { rs.close(); } } { stmt.close(); } so guarantee result sets closed when finished (regardless of exceptions) , statements closed (regardless of exceptions)? there other ways write that, idea same. if you're doing of properly, unless have many references it's taking inordinate amount of memory, it's ok , nothing needs done it.
