LOV with splitted data

I found an easy technique to visualize data in lov's like this:



Use multiple UNION ALL's to concatenate the data :

select '---new colleagues---' ename, NULL job, NULL hiredate
 from dual
UNION ALL
select ename, job, to_char (hiredate, 'DD.MM.YYYY')
 from emp where hiredate >= to_date ('01.07.1981', 'DD.MM.YYYY')
UNION ALL
select '---before 07/81---' ename, NULL job, NULL hiredate
 from dual
UNION ALL
select ename, job, to_char (hiredate, 'DD.MM.YYYY')
 from emp where hiredate < to_date ('01.07.1981', 'DD.MM.YYYY')

have fun and use it
