Reading from CLOB..Clolumn from table

Question

Hi,
I would like to know the reading data from CLOB Column can any one help in this regard,
I had written some code but I would like to loop it..
Please see the code given below :-
DECLARE
lobloc CLOB;
buffer VARCHAR2(32000);
amount NUMBER := 200;
amount_in_buffer NUMBER;
offset NUMBER := 1;
BEGIN
--Initialize buffer with data to be inserted
SELECT f_large_value
into lobloc
FROM T_PRODUCT_BRAND_PARAMS
WHERE F_BRAND_ID='PPNET' AND F_PRODUCT_ID ='CASINO'
     AND F_KEY LIKE '%TAB_CONFIG%';
dbms_lob.read(lobloc,amount,offset,buffer);
--using length built-in function to find the length of the buffer
amount_in_buffer := length(buffer);
dbms_output.put_line(buffer);
-- dbms_output.put_line(to_char(amount_in_buffer));
END;
where f_large_value is clob column,
when I executed its given oly first 5 lines of the data..
I would like to loop it can any one suggest me... in this regard
Thanks

Answer 1

Hi,
I am using BO Data Integrator as ETL tool, can you specify how will I 'split the data loads' or 'read the data in mutliple passes' ? Is it by using multiple Query Transform with different Where clause as filters? eg. 'by period' and  'by year'?
Query_1 filter:
year = 2006
Query_2 filters:
year = 2007
Merge:
Query_1 and Query_2
Thanks again!
