How to to display entire records using PL/SQL(anoyomous block)

Question

Hi All,
I have created a region of type PL/SQL by using rownum, and it wil display few records due to rownum.
But the end user is asking to display the rest of records also using some pagination concept or any other way.
How can we achieve this?
In mean time i have tried to execute the by removing the rownum, then it is throwing the below Query
Error- ORA-06502: PL/SQL: numeric or value error: character string buffer too small.
Thanks,
Ano.

Hi,
Here is the query we are using to dsipaly the records, but the limit we are dsiplaying is only 300.
So the concern is how we can display all records.
DECLARE
list_arr2 htmldb_application_global.vc_arr2;
p VARCHAR2(4000);
v_default_start_date DATE;
j NUMBER :=0;
occurrencies NUMBER(10);
CODESELECT VARCHAR2(7);
BEGIN
IF :P2_SYMBOL_CODE_HIDDEN IS NOT NULL THEN
CODESELECT:=:P2_SYMBOL_CODE_HIDDEN;
ELSE
CODESELECT:='';
END IF;
Select TO_char(SYSDATE-1,'MM/DD/YYYY') into v_default_start_date from Dual;
:P2_START_DATE := v_default_start_date; */
list_arr2 := htmldb_util.string_to_table (:P2_SYMBOL_NAME, ',');
p := 'SELECT SYMB_SARUS_DESCRIPTION,SYMB_CODE FROM ( '
|| 'SELECT '''' SYMB_SARUS_DESCRIPTION,''NA'' SYMB_CODE FROM DUAL ';
p := p
|| ' UNION all SELECT sym.SYMB_SARUS_DESCRIPTION || ''- '' '
|| ' || sym.SYMB_CODE SYMB_SARUS_DESCRIPTION , sym.SYMB_CODE '
|| ' from T_SYM sym ';
IF :P2_ACTIVESYMBOL='ACTIVE ONLY' THEN
p := p || ', ( SELECT distinct DSPS_SYMB_CODE FROM t_dispatch_symbol ' ||
' WHERE dsps_dsp_code IN ( SELECT adsp_dsp_code ' ||
' FROM t_aut ' ||
' WHERE adsp_vend_code=''FTP'' ' ||
')) act_symb ' ||
' WHERE sym.SYMB_CODE=act_symb.DSPS_SYMB_CODE AND ';
ELSIF :P2_ACTIVESYMBOL='INACTIVE' THEN
p := p || ', ( SELECT distinct DSPS_SYMB_CODE FROM t_dis ' ||
' WHERE dsps_dsp_code NOT IN ( SELECT adsp_dsp_code ' ||
' FROM t_aut ' ||
' WHERE adsp_vend_code=''FTP'' ' ||
')) act_symb ' ||
' WHERE sym.SYMB_CODE=act_symb.DSPS_SYMB_CODE AND ';
ELSE
p := p || ' WHERE ';
END IF;
p := p || 'UPPER(sym.SYMB_SARUS_DESCRIPTION) LIKE ';
FOR i IN 1 .. list_arr2.COUNT
LOOP
IF i = 1
THEN
p := p || ' UPPER(''%' || TRIM(list_arr2 (i)) || '%'') ';
ELSE
p :=
p
|| ' AND UPPER(SYMB_SARUS_DESCRIPTION) LIKE '
|| ' UPPER(''%'
|| TRIM(list_arr2 (i))
|| '%'') ';
END IF;
END LOOP;
p := p || ' order by 1 ) where rownum < 310 ';
p := REPLACE(p, '''||''', '||');
IF LENGTH(:P2_SYMBOL_NAME) > 2 AND :P2_HIDD = 'cdf' THEN
htp.p('<table>');
htp.p('<tr bgcolor=white><td width=20% align="left">');
htp.p('<font color="#094991" size="1">     Search By Name</font>');
htp.p('</td>');
htp.p('<td align="left">');
htp.p(APEX_ITEM.SELECT_LIST_FROM_QUERY(3,CODESELECT,p,'onChange="setSymbolCode(this.value);" size=10','NO','','','P2_SEARCHNAME','','Select'));
htp.p('</td>');
htp.p('</tr>');
htp.p('</table>');
END IF;
IF LENGTH(p)<=0 THEN
:P2_SYMBOL_CODE_HIDDEN:='';
END IF;
END;
Thanks,
Anoo.
