Hi,
I wonder if there's a better way of writing the query below. Basically, I
would like to return employee records where employee name='JOSE' + all
employees in deptno=50. My query can have multiple 'OR' criterias where the
next criteria maybe returning all employees with salary>60000 in addition to
the above two criterias. Building the query with multiple UNIONs will
definitely degrade the query performance. Is there a better way of rewriting
the query?
Thanks!

where e.deptno=d.deptno and d.deptno=50;
