Hi


TB_view descrption.

Name        Null Type         
----------- ---- ------------ 
ACC_HEAD         VARCHAR2(28) 
TYPE             CHAR(1)      
AMOUNT           NUMBER       
DESTINATION      CHAR(1)

it has total 23 rows



i am running a simple query against the view;



select * from tb_view where destination='E';


The result is (4 rows)

ACC_HEAD                     T     AMOUNT D
---------------------------- - ---------- -
INVESTMENT                   C          0 E
OWNER EQUITY                 C   -7.0E+06 E
SALES RETURN                 D          0 I
WITHDRAWS                    D          0 E

How come SALES RETURN is selected despite the fact it has "I" value on destination column.

SALES RETURN also shows when i re-run query with destination !='E' (gives me 20 rows)



Very strange and upset behavior.

Any tip?

Since you did not provide sufficient detail for us to reproduce what you claim, your only recourse is to submit Bug Report to MOS.

Either Oracle is correct & you are mistaken or you are correct & Oracle has a bug that needs to be fixed.

Made a little change in defining TB_VIEW and made the destination 'X' for sales return.
and the core part is
....
UNION
SELECT 'SALES RETURN', 		'D', 	nvl(sum(NVL(sum(NVL(uprice,0)*NVL(QTY,0)),0) - (nvl(invcashz,0) +nvl(invcashz1,0) )),0), 'X'
					from inv0p b, inv1p c 
					where b.invno=c.invno
					and ccode not in (select ccode from cust where godown='Y')
					and b.return2='Y'
					group by invcashz, invcashz1
UNION
....


Here are few queries and result

The full view definition along with the explain plan may help show what's gone wrong.
That said - this is absolutely a bug and you should really be talking to oracle support about getting it fixed.

does the error go away if you change your CHAR(1) definitions to VARCHAR(1)?

Its a view and thus has made its type itself as my view starts as follows:

CREATE OR REPLACE VIEW TB_VIEW (ACC_HEAD, TYPE, AMOUNT, DESTINATION)
AS
SELECT 'INVENTORY', 		'D', NVL(SUM(OST*OP),0)	, 'I'	FROM PROD
UNION
...

The result is corrected if i changed the code as follow (though this is not my desired output but i made it simplified to test/rectify)

...
UNION
SELECT 'SALES RETURN', 		'D', 	NVL(sum(NVL(uprice,0)*NVL(QTY,0)),0) , 'I'
					from inv0p b, inv1p c 
					where b.invno=c.invno
					and ccode not in (select ccode from cust where godown='Y')
					and b.return2='Y'
					UNION
...


while original/problemtic code was

....
UNION
SELECT 'SALES RETURN', 		'D', 	nvl(sum(NVL(sum(NVL(uprice,0)*NVL(QTY,0)),0) - (nvl(invcashz,0) +nvl(invcashz1,0) )),0), 'I'
					from inv0p b, inv1p c 
					where b.invno=c.invno
					and ccode not in (select ccode from cust where godown='Y')
					and b.return2='Y'
					group by invcashz, invcashz1
UNION
....


How can we compare both codes and predict possibility of error?

Providing a functioning test case so people can reproduce your issue rather than simply read your description of it is the only way.
