Dear, Mr.David

Hi to all, I need some idea or suggestion to my program. Now I have one master and detail relation. In the detail block I have 1 data item called amount. Data type of amount are number and have positive and negative number. I now i need fetch the number to another 2 column call debit(+ve value) and credit(-ve value). So, how I can assign the data value to column?

Use a post-query trigger to populate the new fields on retrieval, and in the when-validate-item, populate the field when the data is changed.

Search for 'calculate' in this forum. For example http://www.orafaq.com/forum/m/120861/67467/?srch=calculate#msg_120861.

hi,
you can try this
select decode(sign(:amount),1,abs(:amount),0) debit
,decode(sign(:amount),-1,abs(:amount),0) credit
INTO :block_name.debit,:block_name.credit
from dual

put this code in post query of the detailed block as well as
the when validate item of the amount.

regards
yogeshwar.

Try the following in your Post-Query trigger:

IF nvl(:amount,0) < 0 then
:block_name.debit = :amount;
ELSE
:block_name.credit = nvl(:amount,0);
END IF;
