Problem in joined Select with aliases

hey there!
can anybody tell my what's wrong with the following DB2 query?:

SELECT
ss.id as screen,
sp.id as id,
sp."_template" as template,
ss."_template" as screen_template,
ss.displaysecond
FROM
slideshow_part as sp
LEFT JOIN
slideshow_screen as ss ON
ss."_slideshow_part" = sp.id
WHERE
sp."_slideshow" = 95
ORDER BY
sp.sortorder ASC,
sp.id ASC,
ss.displaysecond ASC,
ss."_template" ASC

db2 complains that SP.ID was invalid.

i can say that the table structures match, i even tried to get rid of all those aliases, but no success at all...

Error code?

What error code and/or sqlerror code are you getting?

Type at your promt: db2 ? "errorcode"

I know this isnt a solution but you can narrow your search from this.

Hope this helps

i don't have db2 to test on, but i will guess that you cannot alias a column name to the same name

try changing it to

Code:

select ss.id as screen
     , sp.id as foo
     , sp."_template" as template
     , ss."_template" as screen_template
     , ss.displaysecond
  from slideshow_part as sp 
left 
  join slideshow_screen as ss 
    on sp.id 
     = ss."_slideshow_part"
 where sp."_slideshow" = 95 
order 
    by sp.sortorder asc
     , sp.id asc
     , ss.displaysecond asc
     , ss."_template" asc
