-

i have table- 

empl id  eff seq  emp name     date         action  20140531    1      abc         05-may-08      hired  20140531    1      abc         05-jun-08      termin  20140531    1      abc         15-dec-08      rehired 20158888    1      xyz         25-jan-10      hired 20158888    1      xyz         05-may-10      termin 20156666    1      bbb         12-feb-12      hired 20157777    1      aaa         05-may-13      hired

so if write query on above database, should return emplid-

  • 20140531

as employee rehired within year termination date. wondering how can results.

assuming table defined as

create table empls(emplid       number,                    eff_seq      number,                    emp_name     varchar2(10),                    action_date  date,                    action       varchar2(10));

and populated data specified in question following query you're looking for:

with rehired_empls (select *                          empls                          action = 'rehired'),      terminated_empls (select *                             empls                             action = 'termin') select distinct r.emplid   rehired_empls r   inner join terminated_empls t     on t.emplid = r.emplid   t.action_date between r.action_date - interval '1' year                           , r.action_date;
