Error message downloading OBIEE Report to Excel "is in a different format"

702906Nov 3 2009 — edited Nov 3 2009
Dear experts:

We just upgraded to 10.1.3.4.1 in our Dev environment and are seeing a pecuiliar behavior when we try to download a report to either "Excel" or "Excel 2000".

After selecting Excel (or Excel 200) from the Download Link, we get the following message that pops up:

The file you are trying to open 'Period Summary.xls' is in a different format than specified by the file extension. Verify the file is not corrupted and is from trusted source before opening the file. Do you want to open the file now?

We are then given the choice of Yes, No, or Help

When I click Yes, the File does open, but why this message? I can see the users complaining about this message.

You can write it down explicitly like this:

select * from employee_view  
where 
    :p_cnic = 'YES' and emp_cnic is not null or 
    :p_cnic = 'NO'  and emp_cnic is null

Whilst order of precedence works, for clarity of reading (and to ensure future lazy developers don't break it so easily), I always prefer to use parentheses/brackets around my OR clauses...

select * from employee_view  
where 
    (    :p_cnic = 'YES'
     and emp_cnic is not null
    )
    or
    (    :p_cnic = 'NO'
     and emp_cnic is null
    )

Just makes it absolutely clear which clauses belong with which other clauses. Nothing worse than a future developer coming along adding another "and" clause thinking it will apply to everything but they've not seen the OR statement and then it's not working as it should.

Hi Muhammad,
here's a little correction of the query of cormaco and BluShadow to satisfy your requirement to select all records if no value is passed:

SELECT *
  FROM employee_view
 WHERE    ( :p_cnic = 'YES' AND emp_cnic IS NOT NULL)
       OR ( :p_cnic = 'NO' AND emp_cnic IS NULL)
       OR ( :p_cnic IS NULL)

Best regards
Jan

Hi, [Muhammad Masoom Ansari](/ords/forums/user/Muhammad Masoom Ansari)
Here's another way to write the WHERE clause, that's a little more concise:

WHERE  :p_cnis IS NULL
OR     :p_cnis = NVL2 (emp_cnis, 'YES', 'NO')

I tried with decode function but I think it don't support the "not null"
Right. DECODE must return a value in one of the SQL data types, such as VARCHAR2 or NUMBER. That means, the 3rd, 5th, ... arguments must all be expressions that result in the same kind of SQL data type. But
emp_cnis is not null
is a BOOLEAN expression, and there is no BOOLEAN data type in SQL.

Hi Muhammad,
be aware that your "... all records should be viewed" requirement is not met by your query.
Best regards

@frank-kulash
a little more concise
lnnvl(:p_cnis = NVL2 (emp_cnis, 'NO', 'YES'))

Hi @Jan Gorkow
Thank you very much for pointing out, now its fine.
select emp_id,emp_name,emp_cnic
from employee_view a
where a.emp_id in ( select distinct emp_id from hml_emp_attend_register where month_id = :p_month )
and ( (:p_cnic = 'YES' and emp_cnic is not null) or
( :p_cnic = 'NO' and emp_cnic is null)
or (:p_cnic is null and (emp_cnic is not null or emp_cnic is null))
)

Hi, [Muhammad Masoom Ansari](/ords/forums/user/Muhammad Masoom Ansari)
There's no point in saying
 or  (:p_cnic is null and (emp_cnic is not null or emp_cnic is null))  
Simply say

 or  (:p_cnic is null)  

instead.

Hi @frank-kulash
Yes, correct working suggested by you.
Thank you.
