Query in PL/SQL Help

Question

Hi All!
I want to write following type of query in PL/SQL
How can I write one which will work.
SELECT count(1) INTO v_count2 from TRJ_TRAN_REJ_T a and PEU_PUR_ENRL_UNT_T b
where a.TRJ_CVRG_PER_DATE IN (b.PEU_EFF_DATE AND b.PEU_END_DATE) AND
a.purik = b.purik AND a.peuik = b.peuik
Above query is not working correctly. Any changes?? DATE stored in database is like 01/01/2001
v_count2 is NUMBER variable declared in PL?SQL.

I'd also watch out for the TIME part of the date matching, best to do a TRUNC on them, but make sure also [purik] and [peuik] are indexed. This is the format I use for a select. Some parts were removed but you get the idea.
--[START]
--[SELECT]
SELECT
--/*+ choose */
/*+ RULE */
--/*+ first_rows */
--/*+ all_rows */
count(1)          --[C1]
--[INTO]
INTO
v_count2          --[V1]
--[FROM]
FROM
trj_tran_rej_t T1,
peu_pur_enrl_unt_t T2
--[WHERE]
WHERE
TRUNC(T1.trj_cvrg_per_date) = TRUNC(T2.peu_eff_date)
OR
TRUNC(T1.trj_cvrg_per_date) = TRUNC(T2.peu_end_date)
AND
T1.purik = T2.purik
AND
T1.peuik = T2.peuik
--[ABORT]
AND 1=1;
--[END]
