Hello All,

I have used this code in formula column of my report. but an error

Error A READ-ONLY bind variable used in OUT or IN-OUT context

The error is at :STATUS :='L';

Can any one please let me know what the solution for this ?

This is the code

function CF_ORDER_STATUSFormula return Varchar2 is
x date;
begin
select DATE_SCHEDULED+1 into x from wsh_delivery_details;
if ( :STATUS in ('R', 'Y')
And ( rtrim(:CF_ORDER_DISPATCHED) is not null )) then
if :ASOF_DATE > x + 21 then
:STATUS:='L';
return :CF_ORDER_DISPATCHED;
else
return :STATUS;
end if;
end if;
end;

Thanks
Aiyaz

Just put your logic in the main query.
You don't need a formula column for this.

By the way, unless "wsh_delivery_details" table always contains one row, your code might end up with an error (such as TOO-MANY-ROWS or NO-DATA-FOUND).

Hi,
Thanks for the reply

Yes you are right it returns more than 1 rows so i updated the code like this
but when i declare variable x and assigning 'L' to it and run the report then at the run time it gives formula column does not return any value.so, Instead i have created one more formula column in which it will return 'L'. Its working fine now but for some cases its returning 'R' with out checking the if condition of date >21.

Could you please get me a solution for this why its happening.

function CF_ORDER_STATUSFormula return Varchar2 is
--x varchar2(1):='L';
begin

if ( :STATUS in ('R', 'Y')
And ( rtrim(:CF_ORDER_DISPATCHED) is not null )) then
if :ASOF_DATE > :AVAIL_EXP_SHIP_DT + 21 then
return :CF_SCHEDULE;
--return x;
--:STATUS:='L';
end if;
return :CF_ORDER_DISPATCHED;
else
return :STATUS;
end if;
end;

Thanks for all your support

Finally i got updated the code like this

function CF_ORDER_STATUSFormula return Varchar2 is
begin

if ( :STATUS in ('R', 'Y')
And ( rtrim(:CF_ORDER_DISPATCHED) is not null )) then
return :CF_ORDER_DISPATCHED;
else
if :AVAIL_EXP_SHIP_DT > :ASOF_DATE+ 21 then
return :CF_SCHEDULE;
else
return :STATUS;
end if;
end if;
end;

Hope there is no issues in it...
Thanks
