How can I do a conditional SQL?

Hello,
How can I make my SQL work conditionally in the WHERE Clause? 
This is the sense that I have:

:is_admin := case when (select ROL_ID from F_ASR_USERS WHERE Trim(USER_IDENTITY) = Trim(coalesce(sys_context('APEX$SESSION','APP_USER'),user))) = 1 then 1 else 0 end;
--IMPORTANT
--IF :is_admin = 1 MUST GET ALL RECORDS (admin)
--IF :is_admin = 0 MUST BRING ONLY CUSTOMER DATA (client)


select 
  FQ7076E3.FEQ70NN as "Numero_Comprobante",
  FQ7076E3.FEQ70NAU2 as "Numero_Autorizacion",
  F0101.ABTAX as "RUC_Emisor",
  to_date(to_date(1900000 + FQ7076E3.FEIVD, 'yyyyddd'),'DD/MM/YYYY') as "Fecha_Emision",
  to_date(to_date(1900000 + FQ7076E3.FEUPMJ, 'yyyyddd'),'DD/MM/YYYY') as "Fecha_Autorizacion",
  FQ7076E3.FETAX as "ID_Fiscal",
  FQ7076E3.FEALPH as "Razon_Social",
  DOCUMENT_TYPE_1,
  sys.dbms_lob.getlength("DOCUMENT_TYPE_1")"Archivo_PDF",
  DOCU.DOCUMENT_FILENAME_1,
  DOCU.DOCUMENT_MIMETYPE_1,
  DOCUMENT_TYPE_2,
  sys.dbms_lob.getlength("DOCUMENT_TYPE_2")"Archivo_XML",
  DOCU.DOCUMENT_FILENAME_2,
  DOCU.DOCUMENT_MIMETYPE_2
 from F0101 F0101,
  F0010 F0010,
  FQ7076E3 FQ7076E3,
  F_ASR_DOCUMENTS DOCU
 where FEDL02='03' 
  and FEQ70DTP='2'
  and FQ7076E3.FECO=F0010.CCCO
  and F0010.CCAN8=F0101.ABAN8
  -- If user is admin it shows all records
  and FQ7076E3.FEQ70NN = DOCU.DOCUMENT_ID(+)
and ( :is_admin = 1 or ( :is_admin = 0 and trim(FQ7076E3.FETAX) = Trim(coalesce(sys_context('APEX$SESSION','APP_USER'),user)) ))

Runs, but does not show data and only works if I remove the variable and the line ( ( :is_admin = 1 or ( :is_admin = 0 and trim(FQ7076E3.FETAX) = Trim(coalesce(sys_context('APEX$SESSION','APP_USER'),user))) ))

Consider using PL/Scope

PL/Scope Enhancements in Oracle Database 12c Release 2 (12.2) (0 Bytes)It is simpler than parsing code.

How its work I admit that I am a beginner in the world of plsql and I told myself that it is possible to do it with regexp

User_H3J7U

it can be for example standard package, ULT_HTTP
UTL_HTTP Constants

undefined (0 Bytes)You need to set some session settings like this:

ALTER SESSION SET PLSCOPE_SETTINGS='IDENTIFIERS:ALL, STATEMENTS:ALL';

Then compile the package, and then query the dictionary tables being populated when you compile PL/SQL and have set PLSCOPE settings.
In the article I mentioned there is an example :
image.pnghere you would see that variable L_NUM and L_STR are declared on lunes 6 and 7, and that they reference the NUMBER and CHARACTER datatypes. You can modify the query in the example to filter only "VARIABLE" as TYPE; "DECLARATION" as USAGE and then get the associated REFERENCE row to get the datatype.

Poster mentioned ANY package, documentation exists only for Oracle provided packages.
