ORA-01839 "date not valid for month specified" for to_date in where clause

I have following query (BOCRTNTIME - varchar e.g 2015-02-28 12:21:45, VIEW_BASE_MARIX_T - some view):

select BOCRTNTIME
    from VIEW_BASE_MARIX_T
    where to_date(substr(BOCRTNTIME,1,10),'YYYY-MM-DD')
        between (to_date ('2016-01-01', 'YYYY-MM-DD'))
            and (to_date ('2016-02-01', 'YYYY-MM-DD'))

On executing I get error:

ORA-01839:  "date not valid for month specified"

I thought that there are can be incorrect data in BOCRTNTIME, so execute following query:

select distinct
         substr(BOCRTNTIME,1,8),
         substr(BOCRTNTIME,9,2)
  from VIEW_BASE_MARIX_T
 order by substr(BOCRTNTIME,9,2);

But everything looks fine: http://pastebin.com/fNjP4UAu. Also following query executes without any error:

select to_date(substr(BOCRTNTIME,1,10),'YYYY-MM-DD') 
  from VIEW_BASE_MARIX_T;

I already tried add trunc() to all to_date() but no luck. Also I create pl/sql procedure that takes one by one item form VIEW_BASE_MARIX_T and convert it to date - and everything works just fine. Any ideas why I get error on first query?

UPD: Query on table that used in view works fine, but in view - not

UPD2: We have few enviroments with same products, but get error only on one

UPD3: Issue was resolved by search non valid dates in table that used in view

It might be a long shot but between doesn't have parenthesis in it's syntax, have you tried removing them?

select
    BOCRTNTIME
    from VIEW_BASE_MARIX_T
    where 
    to_date(substr(BOCRTNTIME,1,10),'YYYY-MM-DD') between to_date ('2016-01-01', 'YYYY-MM-DD') and to_date ('2016-02-01', 'YYYY-MM-DD')

A bit too long for a comment - create a simple function to test the dates:

CREATE FUNCTION is_Valid_Date(
  in_string VARCHAR2,
  in_format VARCHAR2 DEFAULT 'YYYY-MM-DD'
) RETURN NUMBER DETERMINISTIC
AS
  dt DATE;
BEGIN
  dt := TO_DATE( in_string, in_format );
  RETURN 1;
EXCEPTION
  WHEN OTHERS THEN
    RETURN 0;
END;
/

Then you can do:

SELECT BOCRTNTIME
FROM   VIEW_BASE_MARIX_T
WHERE  is_Valid_Date( substr(BOCRTNTIME,1,10) ) = 0;

You will possibly find that April, June, September or November have an entry for the 31st of that month or February has values greater than 28/29th (although I can't see anything like that in your pasted data).

Otherwise you could try using ANSI Date literals:

SELECT BOCRTNTIME
FROM   VIEW_BASE_MARIX_T
WHERE  to_date(substr(BOCRTNTIME,1,10),'YYYY-MM-DD') between DATE '2016-01-01' and DATE '2016-02-01';

or, even simpler, given the format of the input:

SELECT BOCRTNTIME
FROM   VIEW_BASE_MARIX_T
WHERE  substr(BOCRTNTIME,1,10) between '2016-01-01' and '2016-02-01';

I think that what might be happening is that Oracle is pushing the predicate to the underlying tables of the view.

Have you tried to run the query

select to_date(substr(BOCRTNTIME,1,10),'YYYY-MM-DD') BOCRTNTIME
from MY_TABLE

instead of querying the view?

you can also confirm this by using the NO_PUSH_PRED hint

select /*+ NO_PUSH_PRED(VIEW_BASE_MARIX_T) */
BOCRTNTIME
from VIEW_BASE_MARIX_T
where 
to_date(substr(BOCRTNTIME,1,10),'YYYY-MM-DD') between (to_date ('2016-01-01', 'YYYY-MM-DD')) and (to_date ('2016-02-01', 'YYYY-MM-DD'))

The error message says that you have an invalid day in your month. Check your data with this:

-- Check for months with 30 days
select substr(BOCRTNTIME,9,2), substr(BOCRTNTIME,6,2) from VIEW_BASE_MARIX_T where to_number(substr(BOCRTNTIME,6,2)) in (4,6,9,11) and to_number(substr(BOCRTNTIME,9,2))>30;

-- Check for february
select substr(BOCRTNTIME,9,2), substr(BOCRTNTIME,6,2) from VIEW_BASE_MARIX_T where to_number(substr(BOCRTNTIME,6,2))=2 and to_number(substr(BOCRTNTIME,9,2))>28;
