Pl/sql function querying 2 tables based on bind variable

Question

hey guys, I'm pretty new to pl/sql, but basically I just want to use a select statement based on a searchfield that pulls from 1 of 2 tables based on a bind variable. Here's what I've got so far, but I'm gettting an error message:
declare
q1 varchar2(32767); -- query
q2 varchar2(32767); -- query
begin
q1 := 'select distinct(CBP_CONTENT_CATEGORY) CATEGORY, ' ||
' CBP_FIELDNAME FIELDNAME, ' ||
' CBP_CONTENT_DESC DESCRIPTION ' ||
' from CBP_METADATA_2005 ' ||
' WHERE UPPER(CBP_CONTENT_CATEGORY) LIKE '%' || UPPER(:CBP_SEARCHFIELD) || '%'
' or UPPER(CBP_CONTENT_DESC) LIKE '%' || UPPER(:CBP_SEARCHFIELD) || '%';
q2 := 'select distinct(CBP_CONTENT_CATEGORY) CATEGORY, ' ||
' CBP_FIELDNAME FIELDNAME, ' ||
' CBP_CONTENT_DESC DESCRIPTION ' ||
' from CBP_METADATA_2004 ' ||
' WHERE UPPER(CBP_CONTENT_CATEGORY) LIKE '%' || UPPER(:CBP_SEARCHFIELD) || '%'
' or UPPER(CBP_CONTENT_DESC) LIKE '%' || UPPER(:CBP_SEARCHFIELD) || '%';
if :CBP_YEAR = '1' THEN
q1=q1
RETURN q1
ELSIF :CBP_YEAR = '0' THEN
q2=q2
end if;
RETURN q1;
end;
and here's the error:
failed to parse SQL query:
ORA-06550: line 1, column 8:
PLS-00103: Encountered the symbol "" when expecting one of the following:
begin function package pragma procedure subtype type use

The symbol "" was ignored.

LDub,
Your function is full of errors. First of all you didn't escape quotes and second, you didn't use the concatination operator properly. Beside that, there was a bit too much of code there. Here is the modified code that will work for you:
DECLARE
q1 VARCHAR2 (32767); -- query
q2 VARCHAR2 (32767); -- query
BEGIN
q1 :=
'select distinct(CBP_CONTENT_CATEGORY) CATEGORY, '
|| ' CBP_FIELDNAME FIELDNAME, '
|| ' CBP_CONTENT_DESC DESCRIPTION '
|| ' from CBP_METADATA_2005 '
|| ' WHERE UPPER(CBP_CONTENT_CATEGORY) LIKE ''%'' || UPPER(:CBP_SEARCHFIELD) || ''%'''
|| ' or UPPER(CBP_CONTENT_DESC) LIKE ''%'' || UPPER(:CBP_SEARCHFIELD) || ''%''';
q2 :=
'select distinct(CBP_CONTENT_CATEGORY) CATEGORY, '
|| ' CBP_FIELDNAME FIELDNAME, '
|| ' CBP_CONTENT_DESC DESCRIPTION '
|| ' from CBP_METADATA_2004 '
|| ' WHERE UPPER(CBP_CONTENT_CATEGORY) LIKE ''%''|| UPPER(:CBP_SEARCHFIELD) || ''%'''
|| ' or UPPER(CBP_CONTENT_DESC) LIKE ''%'' || UPPER(:CBP_SEARCHFIELD) || ''%''';
IF :cbp_year = '1'
THEN
RETURN q1;
ELSIF :cbp_year = '0'
THEN
RETURN q2;
END IF;
END;
