SyncSort Problem

Postby JohnDev » Thu Jul 14, 2016 5:21 pm

Hi All,

I have a task that sounds incredibly simple but I cannot get to work. I have 2 input files, FB, LRECL 80. They both have a composite key (1,8,A,17,9,A).

I have to merge these two files into a single output. In the event of a duplicate keys then only the input from file 2 should be written to output.

This card outputs the duplicates from file 2, but not the unmatched records. Any help or advice would be greatly appreciated

//SYSIN    DD *                          
  JOINKEYS FILE=F1,FIELDS=(1,8,A,17,9,A)
  JOINKEYS FILE=F2,FIELDS=(1,8,A,17,9,A)
  JOIN UNPAIRED,F2                      
  REFORMAT FIELDS=(F2:1,80)              
  SORT FIELDS=COPY                      
/*                                      


Thanks

Coded for you - please do it yourself next time

Hello,

Purely out of curiosity, have you tried 'MERGE FIELDS' coupled with a 'SUM FIELDS=NONE'; if I have understood the problem correctly, that should give you what you're looking for.
Can you please, also share some representational data for input/s and output.

Hi Aki,

Thanks for getting back to me. I have tried 'MERGE FIELDS' coupled with a 'SUM FIELDS=NONE' but it doesn't keep the required duplicates from the second output. As an example

F1:
xxxxxxx FUL_USER <--- Key matches first record in F2. This record should be discarded
xxxxxxx GD1_USER115304594FWA
yyyyyyy FUL_USER

F2:
xxxxxxx GBL_USER <--- Key matches first record in F1. This record should be kept
LLLLLLL GD1_USER115303234FWA
ZZZZZZ FUL_USER

Desired Output
xxxxxxx GBL_USER
xxxxxxx GD1_USER115304594FWA
yyyyyyy FUL_USER
LLLLLLL GD1_USER115303234FWA
ZZZZZZ FUL_USER

Hope this helps!

Hello,

Add EQUALS to it and see if it works for you; here is what I tried:

File 1:

BUDDY GUY          
JIMMY FALLON        
STEVE123VAI        
1MACKERALSHAUN      
123JIMIBID          
1234HENDRIX        
123456              
123456              
123456THORN        
146RUPERT              
 


File 2:

FUNTIPERT                            
JIM4573ALLON                        
STEVE123VAI          DONKEY KONG    
1M37547ALSHAUN                      
12GAIJINID                          
1234HENDRIX                          
123456                              
1245727                              
245JIMIBID                          
658DY GUY                            
 


SYSIN:

MERGE FIELDS=(1,2,CH,A,6,2,CH,A),EQUALS
SUM FIELDS=NONE                        
 


When the IN1 DS is FILE-1, SORTOUT:


BUDDY GUY                
FUNTIPERT                
JIMMY FALLON              
JIM4573ALLON              
STEVE123VAI              
1MACKERALSHAUN            
1M37547ALSHAUN            
1234HENDRIX              
12GAIJINID                
123JIMIBID                
1245727                  
123456                    
123456THORN              
146RUPERT                
245JIMIBID                
658DY GUY                
 


When the IN1 DS is FILE-2, SORTOUT:


BUDDY GUY                          
FUNTIPERT                          
JIMMY FALLON                      
JIM4573ALLON                      
STEVE123VAI          DONKEY KONG  
1MACKERALSHAUN                    
1M37547ALSHAUN                    
1234HENDRIX                        
12GAIJINID                        
123JIMIBID                        
1245727                            
123456

146RUPERT                          
245JIMIBID                        
658DY GUY                          
 


Hope this helps.

Edit: Apologies for the tacky input records, cooked them while listening to some good ol' Blues.

Thanks Aki.

That did work, the only issue is that my inputs are unsorted so to use this approach I would need 2 sort steps before the merge. I can achieve what I need with 2 steps and a merge using joinkeys as well. Is there anyway to achieve this in one step?

Thanks again for your time and help

Hello,

I want to avoid that JOINKEYS ;)
Okies, here goes nothing (my input DS were unsorted this time; I simply shuffled the records):

Input:

//IN       DD DISP=(OLD,DELETE,DELETE),DSN=&&TEMP2
//         DD DISP=(OLD,DELETE,DELETE),DSN=&&TEMP1
 


Using:

//TOOLIN   DD *                                    
 SELECT FROM(IN) TO(OUT) ON(1,2,CH) ON(6,2,CH) FIRST
/*                                                  
 


Gives:

BUDDY GUY                          
FUNTIPERT                          
JIMMY FALLON                        
JIM4573ALLON                        
STEVE123VAI          DONKEY KONG    
1MACKERALSHAUN                      
1M37547ALSHAUN                      
1234HENDRIX                        
12GAIJINID                          
123JIMIBID                          
1245727                            
123456                              
123456THORN                        
146RUPERT                          
245JIMIBID                          
658DY GUY                          
 


Whereas, with:

//IN       DD DISP=(OLD,DELETE,DELETE),DSN=&&TEMP1
//         DD DISP=(OLD,DELETE,DELETE),DSN=&&TEMP2
 


Gives:

BUDDY GUY            
FUNTIPERT            
JIMMY FALLON        
JIM4573ALLON        
STEVE123VAI          
1MACKERALSHAUN      
1M37547ALSHAUN      
1234HENDRIX          
12GAIJINID          
123JIMIBID          
1245727              
123456              
123456THORN          
146RUPERT            
245JIMIBID          
658DY GUY            
 


Hope this is what you're looking for.

Edit: This was tested on ICETOOL; so I guess SYNCTOOL should work for you; can you test it once please.

Aki,

That ran with no issue using SYNCTOOL and produced the required output. Thanks again for your quick replies and considered effort.
