SQL conundrum - date filter doesn't work - sql

Question

Really scratching my head here. I have a query that has a date filter. However, I keep getting results that lie outside my date filter period! I have checked that my column is indeed a date column, I have tried using Between and >= <= and none of these seem to have the slightest impact.
Here is an example of my code.
Declare #PARAM_REPORTING_START_DATE as datetime
Declare #PARAM_REPORTING_END_DATE as datetime
Declare #PARAM_CRDTR_ID as integer
Set #PARAM_REPORTING_START_DATE = '2015/06/12'-- 05:39:44 AM'
Set #PARAM_REPORTING_END_DATE = '2015/06/24'-- 05:39:44 AM'
Set #PARAM_CRDTR_ID = 1005
--select #PARAM_REPORTING_START_DATE, #PARAM_REPORTING_END_DATE
Select distinct
capj.cnsmr_accnt_pymnt_jrnl_id,
c.cnsmr_nm_prfx_txt,
c.cnsmr_nm_frst_txt,
c.cnsmr_nm_lst_txt,
capj.cnsmr_accnt_pymnt_pstd_dt,
isdate(capj.cnsmr_accnt_pymnt_pstd_dt) as is_date,
capj.bckt_trnsctn_typ_cd as capj_bckt_trnsctn_typ_cd ,
pm.pymnt_memo_nm
from
cnsmr_accnt_pymnt_jrnl capj
inner join cnsmr_pymnt_jrnl cpj
on capj.cnsmr_pymnt_jrnl_id = cpj.cnsmr_pymnt_jrnl_id
inner join pymnt_memo pm
on pm.pymnt_memo_id = cpj.pymnt_memo_id
inner join crdtr cr
on capj.crdtr_id = cr.crdtr_id
inner join cnsmr_accnt ca
on ca.cnsmr_accnt_id = capj.cnsmr_accnt_id
inner join cnsmr c on c.cnsmr_id = ca.cnsmr_id
Where
capj.cnsmr_accnt_pymnt_pstd_dt>=#PARAM_REPORTING_START_DATE
and
capj.cnsmr_accnt_pymnt_pstd_dt<=#PARAM_REPORTING_END_DATE
and
( -1 IN ( #PARAM_CRDTR_ID ) ) OR ( cr.crdtr_ID in (#PARAM_CRDTR_ID) )

Answer 1

There is a misplacement of braces
Where
capj.cnsmr_accnt_pymnt_pstd_dt>=#PARAM_REPORTING_START_DATE
and
capj.cnsmr_accnt_pymnt_pstd_dt<=#PARAM_REPORTING_END_DATE
and
( -1 IN ( #PARAM_CRDTR_ID ) OR cr.crdtr_ID in (#PARAM_CRDTR_ID) )

Answer 2

You will get all results that satisfy
OR ( cr.crdtr_ID in (#PARAM_CRDTR_ID) )
so the date filter doesn't matter.
You should rearrange the the brackets/braces in your WHERE clause, e.g.
WHERE
capj.cnsmr_accnt_pymnt_pstd_dt
BETWEEN #PARAM_REPORTING_START_DATE AND #PARAM_REPORTING_END_DATE
AND
(
#PARAM_CRDTR_ID = -1
OR
#PARAM_CRDTR_ID = cr.crdtr_ID
);
