PL/SQL block returning error

Question

Hi All,
I have used PL/SQL block in my custom report to search table heading. Basically I have two select list (LOV), user select the parameter from the list and click on go, it displays the report fine when record exists.
I am using following PL/SQL block -
>
DECLARE
v_sql VARCHAR2(4000);
BEGIN
IF :P126_PARK_NAME IS NOT NULL THEN
v_sql := 'select P.OLIC_KEY1, PA.NAME, C.TRADING_NAME, L.LIC_TYPE, P.'|| :P126_PARK_NAME ||', C.COP_ID, L.OLIC_ID Olic_id '
||' from RTT_OP_PARKS_TEMP P, RTT_COMMERCIAL_OPERATORS C , RTT_PARTIES PA, RTT_OP_LICENCES L'
||' where '|| :P126_PARK_NAME || ' IS NOT NULL '
||' AND PA.PAR_ID =C.PAR_ID '
||' AND P.COP_ID =C.COP_ID '
||' AND L.OLIC_KEY1=P.OLIC_KEY1 '
||' AND :P126_QUERY = ''Y'''
||' ORDER BY PA.NAME ';
END IF;
/* debugging */
IF :DEBUG = 'YES' THEN
htp.preopen;
htp.p(v_sql);
htp.preclose;
END IF;
RETURN (v_sql);
END;

Now, I want to use like condition to display all the records by checking the parameters in text field. I have created a new text field and modified the query as follows but it does not work -
>
DECLARE
v_sql VARCHAR2(4000);
BEGIN
IF :P126_PARK_NAME IS NOT NULL THEN
v_sql := 'select P.OLIC_KEY1, PA.NAME, C.TRADING_NAME, L.LIC_TYPE, P.'|| :P126_PARK_NAME ||', C.COP_ID, L.OLIC_ID Olic_id '
||' from RTT_OP_PARKS_TEMP P, RTT_COMMERCIAL_OPERATORS C , RTT_PARTIES PA, RTT_OP_LICENCES L'
||' where '|| :P126_PARK_NAME || ' IS NOT NULL '
||' AND PA.PAR_ID =C.PAR_ID '
||' AND P.COP_ID =C.COP_ID '
||' AND L.OLIC_KEY1=P.OLIC_KEY1 '
||' AND :P126_QUERY = ''Y'''
||' ORDER BY PA.NAME ';
END IF;
IF :P126_MARINE_PARK != -1 THEN
v_sql := 'select distinct L.OLIC_KEY1, PA.NAME, C.TRADING_NAME, L.LIC_TYPE, M.'|| :P126_MARINE_PARK ||', C.COP_ID '
||' from RTT_OP_MARINE_PARKS M, RTT_COMMERCIAL_OPERATORS C , RTT_PARTIES PA, RTT_OP_LICENCES L'
||' where '|| :P126_MARINE_PARK || ' IS NOT NULL '
||' M.'||:P126_MARINE_PARK||' IS LIKE :P126_MARINE_PARK||'%' '
||' AND PA.PAR_ID =C.PAR_ID '
||' AND M.COP_ID =C.COP_ID '
||' AND L.OLIC_KEY1=M.OLIC_KEY1 '
||' AND :P126_QUERY = ''Y'''
||' ORDER BY PA.NAME ';
END IF;
/* debugging */
IF :DEBUG = 'YES' THEN
htp.preopen;
htp.p(v_sql);
htp.preclose;
END IF;
RETURN (v_sql);
END;

Hi Andy,
Thanks for pointing the quotation however it does not work either. Now I am getting -

failed to parse SQL query:
ORA-00933: SQL command not properly ended

Now my query is like below -

DECLARE
v_sql VARCHAR2(4000);
BEGIN
IF :P126_ZONE_NAME IS NOT NULL THEN
v_sql := 'select distinct L.OLIC_KEY1, PA.NAME, C.TRADING_NAME, L.LIC_TYPE, M.'|| :P126_ZONE_NAME ||', C.COP_ID '
||' from RTT_OP_MARINE_PARKS M, RTT_COMMERCIAL_OPERATORS C , RTT_PARTIES PA, RTT_OP_LICENCES L'
||' where '|| :P126_ZONE_NAME || ' IS NOT NULL '
||' AND PA.PAR_ID =C.PAR_ID '
||' AND M.COP_ID =C.COP_ID '
||' AND L.OLIC_KEY1=M.OLIC_KEY1 '
||' AND :P126_QUERY = ''Y'''
||' ORDER BY PA.NAME ';
END IF;
IF :P126_MARINE_PARK IS NOT NULL THEN
v_sql := 'select distinct L.OLIC_KEY1, PA.NAME, C.TRADING_NAME, L.LIC_TYPE, M.'|| :P126_MARINE_PARK ||', C.COP_ID '

END IF;

IF :DEBUG = 'YES' THEN
htp.preopen;
htp.p(v_sql);
htp.preclose;
END IF;
RETURN (v_sql);
END;

Can you tell me how can I display dynamic multiple column in my query? Say in the LIKE condition if user type M in the parameter field and click on go, it must return more than one column starting column name M but in my current query it will only display one column, am I right?
Thanks again for your suggestion.
Kind regards,
