[Q] Using viewCriteria for Date type

Question

To Query data, I used ViewCriteria.
But it works well for Varchar2, Number type.
But it does not work for Date type.
for example
If I set variables like the below, it works,
attrName = "OrdName";
attrValue = "Nick";
But, If I set variables like the below, it does not work
attrName = "AppDate";
attrValue = "04.5.12";
ViewCriteria vc = order.createViewCriteria();
ViewCriteriaRow vcr = vc.createViewCriteriaRow();
vcr.setAttribute(attrName, attrValue);
vc.addElement(vcr);
order.applyViewCriteria(vc);
order.executeQuery();
Can I solve this problem ?

Answer 1

using a custom expression in the view criteria, ex.
vcr.setAttribute("DateField", "LIKE TO_DATE('" + dateField.toString() + "', 'yyyy-mm-dd')");
similarly, you can use other expressions to remove the default BC4J problems w/ dates (>, <, between) - At least I know you can't use = to get it to work right.
The default handling of BC4J is to say = TO_DATE(whatever you put in the value portion) where it needs to be LIKE to work properly - for some reason - probably a patch is available for it.
