Question

i’ve following select:

Select attribut1, dateattribut, attribut3, 
       attribut4, attribut15, town_CODE, count(*)     
from (
select attribut1, dateattribut, attribut3, attribut4, attribut15, (CASE 
  WHEN  TO_CHAR(dateattribut,'YYYY')  = '2005'  THEN 
   CASE town_CODE 
    WHEN '039' THEN  '078' WHEN '050' THEN  '093' 
    WHEN '091' THEN  '008' WHEN '102' THEN  '093' 
   ELSE town_CODE end 
  ELSE town_CODE end) as town_CODE
from towntable) GROUP BY attribut1, dateattribut, 
                        attribut3, attribut4, 
                        attribut15, town_CODE
having count(*) > 1;

when i execute this query on our server it work fine. but on the server of my customer i get the oracle error ORA-00979: not a GROUP BY expression.

As far i found out that im having problems with the Case’s and with the alias.
with out this it works.

any suggestions?

*what i’m trying to do with this statement is to get all double entry’s. with the inner query i change all old codes to the new one, and then i want to group them to see if they exists multiply times.
Some customers did used old codes and now its possible that they have the same town 2 times.

edit

SELECT * FROM product_component_version

and i get on both:

Product                                     Version         Status

NLSRTL                                      10.2.0.4.0      Production
Oracle Database 10g Enterprise Edition      10.2.0.4.0      64bi
PL/SQL                                      10.2.0.4.0      Production
TNS for 64-bit Windows:                     10.2.0.4.0      Production

my test showed me that he doesn’t like calling with the alias.
is there a setting, that alias are not recognized?

Answer 1

My solution is to use an View.

Inner Select as View and then the outer select as normal, and it works fine.

i found out that he doesn’t like town_CODE in the outer select.

Select attribut1, dateattribut, attribut3,
       attribut4, attribut15, town_CODE, count(*)     
from  v_towntable
GROUP BY attribut1, dateattribut, attribut3, 
         attribut4, attribut15, town_CODE
having count(*) > 1
