The (maximum) expected data length is 6, while the returned data length is

Question

I would like to connect the view via the OraOLEDB.Oracle' from linked server of the MSSQL and the following column couldn't be selected.
Msg 7347, Level 16, State 1, Line 2
OLE DB provider 'OraOLEDB.Oracle' for linked server 'PROD' returned data that does not match expected data length for column salary.LATEST_HIRE_DATE_STATUS'. The (maximum) expected data length is 6, while the returned data length is 4.
So I would like to change the following code from case method to decode method ? due to the view can be selected by decode method .
CASE
WHEN TRUNC (latest_hire_date) >= SYSDATE - 90
AND type_of_post = 'Temp'
THEN 'YES'
ELSE 'NO'
END
AS latest_hire_date_status,
CASE
WHEN last_day_of_duty IS NOT NULL THEN 'REJECTED'
ELSE 'PASSED'
END
AS last_day_of_duyty_status,

There's no need to use a DECODE statement when a CASE will do the same, and more, certainly if you want to check for range values rather than equality values as in your ">= SYSDATE - 90".
Not quite sure what your error message means either. Seems to be nonesense as it says the maximum is 6 and it's getting 4, but 4 is not greater than 6 so it shouldn't be a problem.
