How to transfer a null variable to Oracle via a null field?

[merlini]

JS Code
isc.DataSource.get('T_projectApplyDS').fetchData({subID:null},function(){},{operationId:'findSHlist'})
DS Code
<operationBinding operationType="fetch" operationId="findSHlist">
<customSQL><![CDATA[
select * From Table where itemID=$criteria.subID
]]></customSQL>
</operationBinding>

As the code

Expection result is' Select * From Table where itemID=null'(In Sql Server )

But actual result is 'Select * From Table Where itemID=$criteria.subID '(In Oracle )
