sql hibernate and or restrictions

Question

my sql should look like this:

select cell1 from table
where cell2 = 1
and (cell3 = '' or cell3 is null)

But how to do the "and ( x or y )" restricion with hibernate?

Answer 1

What about LogicalExpression

Try this for AND condition:

Criteria cr = session.createCriteria(table.class);

// To get records matching with AND condistions
LogicalExpression andExp = Restrictions.and(cell2, cell3);
cr.add( andExp );

For OR condition use this

 // To get records matching with OR condistions
  LogicalExpression orExp = Restrictions.or(cell2, cell3);
  cr.add( orExp );

 List results = cr.list();
