Error in the Query used in APEX_COLLECTION.CREATE_COLLECTION_FROM_QUERY_B

Question

Dear All,
I am using the following in a PL/SQL Before Header process.
Please help me with the following :
APEX_COLLECTION.CREATE_COLLECTION_FROM_QUERY_B ('LEASE', 'SELECT LSE_NUM
                                                                                                   FROM   RE_LEASE
                                                                                                   WHERE  LSE_COM_NUM = :P0_COM_NUM');I am getting the following error:
ORA-20104: create_collection_from_query_b Error:ORA-20104: create_collection_from_query ExecErr:ORA-01008: not all variables bound
If I change the above as
APEX_COLLECTION.CREATE_COLLECTION_FROM_QUERY_B ('LEASE', 'SELECT LSE_NUM
                                                         FROM   RE_LEASE
                                                         WHERE  LSE_COM_NUM = ' || :P0_COM_NUM);Then I get the following error :
ORA-20104: create_collection_from_query_b Error:ORA-20104: create_collection_from_query ParseErr:ORA-00936: missing expression
I am using the above to create Next and Previous buttons using the reference provided by ATD in the Re: How to do page break
Note: If I do not use any Items in the WHERE as below then I do not get any errors and it works as required.
APEX_COLLECTION.CREATE_COLLECTION_FROM_QUERY_B ('LEASE', 'SELECT LSE_NUM
                                                                                                  FROM   RE_LEASE');I want to use Items in the query for the collection. Please help.
Best Regards

Hi Jari,
Thanks Jari for the reply. Your solution does work as well but please if you can throw some more light on q'! (first line) and !' (last line).
q'!
  SELECT LSE_NUM
   FROM   RE_LEASE
  WHERE  LSE_COM_NUM = (SELECT v('P0_COM_NUM') FROM DUAL)
  !'Best Regards
