Question

I am executing the below query with Oracle ANSI left outer join syntax,It’s returning 107 records:

SELECT  bs_accts.acct_num,  
          bs_accts.acct_name,  
          br_data.record_id ,  
       as_users.username,   
       br_fx.fx_rate ,  
FROM    bs_accts
CROSS JOIN as_users  
CROSS JOIN br_fx
left outer join br_data 
ON (as_users.userid = br_data.last_note_user AND br_fx.iso_src = br_data.user_ten)
WHERE   br_data.state=3       
AND (br_data.acct_id  = bs_accts.acct_id) 
AND (bs_accts.acct_currency='SHS')        
AND     substr(bs_accts.acct_num,1,1)='T'     
AND br_fx.iso_dst = 'USD';

when I am executing the same query without ANSI syntax It’s returning 875 records.I want 875 records with ANSI code.Below is the older left outer join syntax:

SELECT  bs_accts.acct_num,  
          bs_accts.acct_name,  
          br_data.record_id ,  
       as_users.username,   
       br_fx.fx_rate ,  
FROM    bs_accts,as_users,br_fx,br_data
WHERE   br_data.state=3       
AND (br_data.acct_id  = bs_accts.acct_id) 
AND (bs_accts.acct_currency='SHS')        
AND     substr(bs_accts.acct_num,1,1)='T'
AND     br_data.last_note_user=as_users.userid(+)  
AND br_data.user_ten = br_fx.iso_src(+) 
AND br_fx.iso_dst = 'USD';

Is there something wrong with ANSI Code above??

Answer 1

You are using CROSS JOIN, not LEFT OUTER JOIN so it is definitely not the same query.

Your old-style syntax query is wrong, or at least doesn’t contain the outer join to br_fx that you presumably think it does, because of the lack of a (+) symbol on this part:

AND br_fx.iso_dst = 'USD'

That condition negates the (+) used on

AND br_data.user_ten = br_fx.iso_src(+) 

so maybe you meant:

AND br_fx.iso_dst(+) = 'USD'
