NO DATA FOUND [message #165814]

I add a Post-Text-Item trigger on a item textfield, if user key in A item, it query stock table for value of ind, if ind = Y, it will set date textfield as required and enabled. When I run the form and query for data, it shows error

POST-TEXT-ITEM trigger raised unhandled exception ORA-01403
ORA-01403: no data found

the codes are as below,

DECLARE
  ind  stock._ind%TYPE;
BEGIN
  SELECT ind
  INTO   ind
  FROM   stock
  WHERE  item = :form1.item;
  
  IF ind = 'Y' THEN
    Set_item_property('stock.date',
                      required,
                      property_true);
    
    Set_item_property('stock.date',
                      enabled,
                      property_true);
  ELSE
    Set_item_property('stock.date',
                      required,
                      property_false);
    
    Set_item_property('stock.date',
                      enabled,
                      property_false);
  END IF;
END;

I am not sure is the problem because of the null value of ind in stock table. Please advise and give some guide on solving this.

Thanks.

Upd-mod: Please format your code and palce between 'code' tags.

Hi,

In a host language program, all records have been fetched. The return code from the fetch was +4, indicating that all records have been returned from the SQL query.

Try terminate processing for the SELECT statement.

May be this will be helpful.

Pal.

Okay ... either search this forum for 'set_item_property' and then 'set_item_instance_property', or read th ereference manual on these two commands.

You must 'enable' a field before you can make it 'reguired', and you must also make the field 'updateable', and, maybe, 'navigable'.

I would also suggest doing this logic in the When-Validate-Item trigger of the item 'form1.item'.

I also suggest NOT naming your block 'FORM1'. It will become very confusing when you have many blocks and items and you are attacking your form through a flat editor or hex editor.

I have to query from stock table to get the value of ind and thus to determine item property in form1.

Is the problem because of null value return from the select statement? I know the problem is because of it but I don't know why...

Please advise.

On what table is the block 'Form1' based? If the block 'Form1' is based on the table 'stock' that you define the column 'ind' even though you don't display it, then put your logic into the Post-Query trigger and in the When-Validate-Item trigger.

Then the code should be

  SELECT ind
  INTO   ind
  FROM   stock
  WHERE  item = :mtransac.item;

Have you signed on? Have you tested your code at the SQL*Plus prompt having signed on using the same userid?

ORA-01403: no data found

DECLARE
  ind  stock.ind%TYPE;
BEGIN
  SELECT ind

  WHERE  item = :mtransac.item;
  
  IF ind = 'Y' THEN
    Set_item_property('mtransac.date',
                      required,
                      property_true);
    
    Set_item_property('mtransac.date',

What is this?

Quote:

SQL> select ind from stock
2 where item='1002825';

W
-

SQL>

If this was output from 'real' then the 'W' would be an 'I'.

Please try it again. How about using a few items, and show us both the 'item' and 'ind' columns.
