Overrides org.hibernate.hql.internal.ast.tree.SqlNode.getDataType.

Implements org.hibernate.hql.internal.ast.tree.OperatorNode.getDataType, org.hibernate.hql.internal.ast.tree.SelectExpression.getDataType.

Figure out the type of the binary expression by looking at the types of the operands. Sometimes we don't know both types, if, for example, one is a parameter.

Returns:Type
