Hi,

Got a question to ask, suppose I have an object A extending Object B. Supposing Object A has attributes maps to columns of Table A.

Object A(with attributes attrA, attrB) extends Object B(with attributes attrC). Object A is mapped to Table A as such, Table A(column A, column B, column C), through annotations.

When I query Table A using hibernate template. eg

String params[]=new String[2]
params[0]="a";
params[1]="c";
List list=getHibernateTemplate().find("from A where attrA = ? and attrC = ? ",params);

I got the following error that the application is unable to find column attrC. Any idea where I have gone wrong or I should not be doing this.

regards

Thanks to those who have taken a look, I have found my answer.
