Using SYSDATE in Pre-Defined View Criteria ADF BC

Question

I’m trying to setup a View Criteria to find records between two dates. So I create a View Criteria and Select my date field from the table and then choose the “Between” operator and then my operand is a Bind Variable. Then in my Bind variables I have SYSDATE and SYSDATE-7. So in my view.xml I have the following:
<Variable
Name="SystemDate"
Kind="viewcriteria"
Type="java.sql.Date">
<TransientExpression><![CDATA[SYSDATE]]></TransientExpression>
</Variable>
<Variable
Name="Bind_SystemDateMinusSeven"
Kind="viewcriteria"
Type="java.sql.Date">
<TransientExpression><![CDATA[SYSDATE-7]]></TransientExpression>
</Variable>
However, when I try to run this View Criteria (using on an af:query component), I get the following error.
Messages for this page are listed below.
Error     
Unexpected exception caught: java.lang.reflect.UndeclaredThrowableException, msg=null
Error     
Name SYSDATE not found in the given object: ViewRow [oracle.jbo.Key[877 ]
Does anyone know how to do this using ADF BC and View Criterias? I've tried making my bind variables Strings and this doesn't work either. I basically want a predefined query that finds records within a specific week given the system date. Any ideas on how to make this work? Thanks.

You can achieve SYSDATE in ADF BC View Criteria using IsSqlFragment="true".
Below is the VO source code snippet for the same.
<ViewCriteriaItemValue
            Name="ViewObjCriteria_ViewObjSubCriteria1_vcrow40_HireDate_vcval0"
            Value="sysdate-350" IsSqlFragment="true"/>
          <ViewCriteriaItemValue
            Name="ViewObjCriteria_ViewObjSubCriteria1_vcrow40_HireDate_vcval1"
            Value="sysdate" IsSqlFragment="true"/>
</ViewCriteriaItem>
