From clause query works ok in form designer, gets an ORA-01422 ran on web

Question

I am using forms 6i patch 9 with 10g database.
I have two ‘FROM clause queries’ fired via a block/key-exeqry trigger in a if/elsif.
The first/top SET BLOCK PROPERTY works perfect and populates the block.
But the bottom/second SET BLOCK PROPERTY select (after the elsif)
Is also based on a user entered field value and generates a ora-01422 error.
The problem is that both top and bottom set block properties
work fine when ran in forms designer,
But when I compile it on the app_server and run the web version
1. the top all ‘FROM clause query’ works fine
2. the bottom ‘FROM clause query’ works fine if only one record to return.
3. the bottom ‘FROM clause query’: gets the ora-01422 if > 1 record to return.
FRM-40735: KEY–EXEQRY trigger raised unhandled exception ORA-01422
The ORA-01422: ‘Exact fetch returned more than the exact number of rows’.
Both set block property selects ‘share’ a block property/where clause of FAC_ID = :FACILITIES.ID
The entered value in the entry field should populate 1 to many associated records
in the bottom (elsif) set block property (and does so correctly when ran in forms designer)
The block’s key-exeqry code:
–-query all records associated with fac_id only
if (:emission_stacks.stack_id_num is null) then
     SET_BLOCK_PROPERTY('EMISSION_STACKS',QUERY_DATA_SOURCE_NAME,
     '(SELECT C.ID, A.ID EP_ID,A.FAC_ID,A.NUM,A.DESCRIPTION,C.PARENT_MODE_ID,
C.STACK_ID, C.CAPTURE_PERCENT, C.CAPTURE_METHOD, C.DATE_TESTED
FROM EMISSION_POINTS A,
EP_MODES B,
CAPTURING_DEVICES C
WHERE A.ID = B.EP_ID AND
B.ID = C.PARENT_MODE_ID AND
C.CD_ID IS NULL AND
C.PARENT_MODE_ID IS NOT NULL AND
C.STACK_ID IS NOT NULL)');
EXECUTE_QUERY;
elsif
(:emission_stacks.stack_id_num is not null) then
–-(query all records associated with fac_id and the entry field value)
SET_BLOCK_PROPERTY('EMISSION_STACKS',QUERY_DATA_SOURCE_NAME,
     '(SELECT C.ID, A.ID EP_ID, A.FAC_ID, A.NUM, A.DESCRIPTION, C.PARENT_MODE_ID,
C.STACK_ID, C.CAPTURE_PERCENT, C.CAPTURE_METHOD, C.DATE_TESTED
FROM EMISSION_POINTS A,
EP_MODES B,
CAPTURING_DEVICES C,
STACKS S
WHERE A.ID = B.EP_ID AND
B.ID = C.PARENT_MODE_ID AND
C.STACK_ID = S.ID AND
C.CD_ID IS NULL AND
C.PARENT_MODE_ID IS NOT NULL AND
C.STACK_ID IS NOT NULL AND
S.NUM = '''||:emission_stacks.stack_id_num||''')');
EXECUTE_QUERY;
** I have multiple database items in the block.
Data block properties:
Database/
Data Base Block = Yes
Query Allowed= Yes
Is there a way to overcome the ora-01422?
And populate the block with multiple rows(records)?
Any suggestions appreciated.

Answer 1

Sorry, false alarm, I made a mistake
the form is working fine the way it should,
without error. (No ora-01422 errror is occurring now.)
I just got a new version of humming bird,
which I used to compile the form with
and did not have the binary switch on:
--long story short, a new fmx was not created
and I was not seeing the current version of screen
at runtime.
Thank you.
