Add a filter parameter to ssrs report - sql

Question

I have a query that I need to update to allow user to filter out pending applications. I have created the parameter and tried to implement using case but it is not working or giving any error messages on how to correct it. The code is:
select distinct pers.person_fname,
pers.person_mname,
pers.person_lname,
le.nationalprovidernumber NPN,
lic.licensenumber LICENSE_NUMBER,
adr.address_line1 ADDRESS1,
adr.address_line2 ADDRESS2,
adr.address_line3 ADDRESS3,
adr.city CITY,
sp.state_province_name STATE,
adr.postal_code ZIP_CODE,
eml.email,
rtp.residencetype_name RESIDENCY,
ltp.licensetype_name LICENSE_TYPE,
lic.expirationdate DATE_OF_EXPIRATION
from odilic_admin.license lic
inner join odilic_admin.licenseststimeline lst
on lic.license_id = lst.license_id
inner join odilic_admin.licenseststype lstp
on lst.licenseststype_id = lstp.licenseststype_id
inner join odilic_admin.licensedef ldef
on lic.licensedef_id = ldef.licensedef_id
inner join odilic_admin.licensetype ltp
on ldef.licensetype_id = ltp.licensetype_id
inner join odilic_admin.residencetype rtp
on ldef.residencetype_id = rtp.residencetype_id
inner join odilic_admin.licensingentity le
on lic.licensingentity_id = le.licensingentity_id
inner join odilic_admin.individual ind
on le.licensingentity_id = ind.licensingentity_id
inner join odidir_admin.person pers
on ind.person_id = pers.person_id
left outer join odidir_admin.person_address_rel par
on pers.person_id = par.person_id
left outer join odidir_admin.address adr
on par.address_id = adr.address_id
left outer join odidir_admin.address_type atp
on adr.address_type_id = atp.address_type_id
left outer join odidir_admin.state_province sp
on adr.state_province_id = sp.state_province_id
left outer join
(select pr.person_id, em.email_id, em.email
from odidir_admin.person pr,
odidir_admin.person_email_rel pe,
odidir_admin.email em
where pr.person_id = pe.person_id
and pe.email_id = em.email_id
and email_type_id = 2) eml
on pers.person_id = eml.person_id
where
ltp.licensetype_id in (:License_type)
and lstp.licenseststype_name = 'Active'
and atp.address_type_name = 'Mailing Licensing'
and (lic.expirationdate >= current_date and
trunc(lic.expirationdate) = :Expiration_Date)
and sysdate between lst.periodbegindate and lst.periodenddate
order by lic.licensenumber
In order to get applications that are pending I need to access the table odilic_admin.licenseappl and filter out all licenses with appststype = 2 (pending). To do this I added a join to the query before the last left outer join andt hen a case at bottom for when this parameter is selected.
select distinct pers.person_fname,
pers.person_mname,
pers.person_lname,
le.nationalprovidernumber NPN,
lic.licensenumber LICENSE_NUMBER,
adr.address_line1 ADDRESS1,
adr.address_line2 ADDRESS2,
adr.address_line3 ADDRESS3,
adr.city CITY,
sp.state_province_name STATE,
adr.postal_code ZIP_CODE,
eml.email,
rtp.residencetype_name RESIDENCY,
ltp.licensetype_name LICENSE_TYPE,
lic.expirationdate DATE_OF_EXPIRATION
from odilic_admin.license lic
inner join odilic_admin.licenseststimeline lst
on lic.license_id = lst.license_id
inner join odilic_admin.licenseststype lstp
on lst.licenseststype_id = lstp.licenseststype_id
inner join odilic_admin.licensedef ldef
on lic.licensedef_id = ldef.licensedef_id
inner join odilic_admin.licensetype ltp
on ldef.licensetype_id = ltp.licensetype_id
inner join odilic_admin.residencetype rtp
on ldef.residencetype_id = rtp.residencetype_id
inner join odilic_admin.licensingentity le
on lic.licensingentity_id = le.licensingentity_id
inner join odilic_admin.individual ind
on le.licensingentity_id = ind.licensingentity_id
inner join odidir_admin.person pers
on ind.person_id = pers.person_id
left outer join odidir_admin.person_address_rel par
on pers.person_id = par.person_id
left outer join odidir_admin.address adr
on par.address_id = adr.address_id
left outer join odidir_admin.address_type atp
on adr.address_type_id = atp.address_type_id
left outer join odidir_admin.state_province sp
on adr.state_province_id = sp.state_province_id
**left outer join odilic_admin.licenseappl appl
on lic.licensingentity_id = appl.licenseappl_id**
left outer join
(select pr.person_id, em.email_id, em.email
from odidir_admin.person pr,
odidir_admin.person_email_rel pe,
odidir_admin.email em
where pr.person_id = pe.person_id
and pe.email_id = em.email_id
and email_type_id = 2) eml
on pers.person_id = eml.person_id
where
ltp.licensetype_id in (:License_type)
and lstp.licenseststype_name = 'Active'
and atp.address_type_name = 'Mailing Licensing'
and (lic.expirationdate >= current_date and
trunc(lic.expirationdate) = :Expiration_Date)
and sysdate between lst.periodbegindate and lst.periodenddate
**case :pending when = yes then appl.applststype_id !=2
end**
order by lic.licensenumber
Instead of the case I have also tried using an IF with the same result. This looks like:
if :Pending = 1
then
and appl.applststype_id != 2;
end if;
Any help to get me past this is greatly appreciated and I will be sure to vote and select most correct answer to help me solve this.

Answer 1

Assuming that your :pending parameter is a numeric where a value of 1 indicates that pending licences are to be excluded and you only want to exclude licence applications that are pending, try adding the following condition in place of your existing case clause:
and (:pending <> 1 or appl.applststype_id !=2)
