Hi,

I have 2 files, the requirement is to compare key fields in these two files and create an output file with matching records only from the first file. The first file can have duplicates.

File 1

Code:

Key

AAA  1234
AAA  5678
BBB  1234
CCC  1234
CCC  3456
 


File 2
Code:

Key

AAA  7777
CCC  8888


Output file
Code:

Key

AAA  1234
AAA  5678
CCC  1234
CCC  3456



We don't have DFSORT or Ezytrieve in our shop. Can we do this using Syncsort? All suggestions are welcome.

Thanks
Smith.

Smith,

If you have the latest version of syncsort , it supports the SPLICE operator. You can find the solution using splice here

Hope this helps...

Cheers

Kolusu,

I tried splice but I'm getting only the first match from the first file. I'm not getting any subsequent matches. I tried to use WITHALL but it is still the same.

Output got
Code:

AAA  1234
CCC  1234


Desired output
Code:

AAA  1234
AAA  5678
CCC  1234
CCC  3456



Is this possible using sort? Please advice.

Thanks
Smith.

Smith,

Try this JCL

Code:

//STEP0100 EXEC PGM=SYNCTOOL                             
//TOOLMSG  DD SYSOUT=*                                   
//DFSMSG   DD SYSOUT=*                                   
//IN1      DD *                                         
AAA  1234                                               
AAA  5678                                               
BBB  1234                                               
CCC  1234                                               
CCC  3456                                               
//IN2      DD *                                         
AAA  7777                                               
CCC  8888                                               
//T1       DD DSN=&T1,DISP=(,PASS),SPACE=(CYL,(1,1),RLSE)
//T2       DD DSN=&T2,DISP=(,PASS),SPACE=(CYL,(1,1),RLSE)
//CON      DD DSN=*.T2,VOL=REF=*.T2,DISP=SHR             
//         DD DSN=*.T1,VOL=REF=*.T1,DISP=SHR             
//OUT      DD SYSOUT=*                                   
//TOOLIN   DD *                         
  COPY FROM(IN1) USING(CTL1)             
  SORT FROM(IN2) USING(CTL2)             
  SPLICE FROM(CON) TO(OUT) ON(1,3,CH) - 
    WITH(1,80) WITHALL USING(CTL3)       
//CTL1CNTL DD *                         
  OUTFIL FNAMES=T1,                     
  OUTREC=(1,80,3X)                       
//CTL2CNTL DD *                         
  SORT FIELDS=(1,3,CH,A)                 
  OUTFIL FNAMES=T2,                     
  OUTREC=(1,80,1,3)                     
//CTL3CNTL DD *                         
  OUTFIL FNAMES=OUT,                     
  OUTREC=(1,80)                         
/*


The output from this job is

Code:

AAA  1234     
AAA  5678     
CCC  1234     
CCC  3456     


Hope this helps...

Cheers

The desired output was

Desired output
Code:

AAA 1234
AAA 5678
CCC 1234
CCC 1234
CCC 1234
CCC 1234
CCC 3456


I added an omit condition in CTL3CNTL to eliminate the BBB records.
OMIT=(81,2,CH,EQ,C' ')

Thank you very much for your help.

Smith.
