Length of the field data [message #86700]

Hi,

�In When-Record-Instance, i'm trying to some iterations based on the length of the data of the field. A field's data is 344. I have declare a variable�ln_Length type NUMBER(8) and assigning the length of the data field value to it

�ln_Length := LENGTH(:SYSTEM.CURSOR_VALUE);

But ln_Length is showing 255 though the actual data length of field is 344. Because of this my calculations are going wrong.� The problem what I found out was, that the SYSTEM variables can hold chars of length max 255�only.

So Can you pls let me know whats the alterante solution for this. I want to use it in When-New_Record-Instance trigger itself?

Thanks and Regards

AB

Hi,
Try this code:

Declare
L_val Varchar2(1000):=NAME_IN(:system.cursor_item);
Begin
message(L_VAL);
message(length(L_VAL));
End;

HTH
