PostPosted: Fri Sep 23, 2011 12:00 am    Post subject: Join on keys and replace when matched Reply with quote

Hi,

I have File1 with LRECL = 1578 and File2 with LRECL = 279.
In file1 I have 10 char Key from 254-263 whereas in File2 it is from 270-279.
I want to join file1 and File2 on Keys and wherever the key matches replace data at location 9-14 in File1 with data from location 1-6 in File2.
While doing this I want to make sure that we dont change any of the data in File1 for non matching keys.
Please help.
here is an example:
File1
data----------------- Key
(9-14)--------------(254-263)
------ --------------0000000001
------ --------------0000000002
ccccc --------------0000000003

File2
data----------------- Key
(1-6) --------------(270-279)
aaaaa--------------0000000001
bbbbb--------------0000000002


output File1:
data----------------- Key
(9-14)--------------(254-263)
aaaaa--------------0000000001
bbbbb--------------0000000002
ccccc --------------0000000003

Here's a DFSORT JOINKEYS job that will do what you asked for:

Code:

//S1 EXEC PGM=SORT
//SYSOUT DD SYSOUT=*
//IN1 DD DSN=...  input file1 (FB/1578)
//IN2 DD DSN=...  input file2 (FB/279)
//SORTOUT DD DSN=...  output file (FB/1578)
//SYSIN DD *
  JOINKEYS F1=IN1,FIELDS=(254,10,A),SORTED
  JOINKEYS F2=IN2,FIELDS=(270,10,A),SORTED
  JOIN UNPAIRED,F1
  REFORMAT FIELDS=(F1:1,1578,F2:1,6,?)
  OPTION COPY
  OUTFIL IFOUTLEN=1578,
    IFTHEN=(WHEN=(1585,1,CH,EQ,C'B'),
      OVERLAY=(9:1579,6))

I think we dont have PGM=SORT in our setup.
We do use SORTD and ICETOOL. Can we achieve the same results with SORTD and ICETOOL??
Please let me know and thanks for your help!

SORTD is just a SORT PROC. You can use PGM=SORT. Try it.

Or if you want, use SORTD which will do the same thing.

Code:

//S1 EXEC SORTD
//IN1 DD DSN=...  input file1 (FB/1578)
//IN2 DD DSN=...  input file2 (FB/279)
//SORTOUT DD DSN=...  output file (FB/1578)
//SYSIN DD *
  JOINKEYS F1=IN1,FIELDS=(254,10,A),SORTED
  JOINKEYS F2=IN2,FIELDS=(270,10,A),SORTED
  JOIN UNPAIRED,F1
  REFORMAT FIELDS=(F1:1,1578,F2:1,6,?)
  OPTION COPY
  OUTFIL IFOUTLEN=1578,
    IFTHEN=(WHEN=(1585,1,CH,EQ,C'B'),
      OVERLAY=(9:1579,6))

Hi Frank,

The JCL given by you was giving SYNTAX ERRORS in JOINKEYS and REFORMAT.

I modified it and it worked.
here is the JCL:

Code:

//STEP60 EXEC    SORTD                                                 
//SYSOUT  DD SYSOUT=*                                                   
//SORTJNF1 DD DSN=...(FB\1578)                     
//SORTJNF2 DD DSN=...(FB\279)             
//SORTOUT DD DSN=...(FB\1578)                     
//SYSIN   DD *                                                         
    JOINKEYS FILE=F1,FIELDS=(254,10,A),SORTED                           
    JOINKEYS FILE=F2,FIELDS=(270,10,A),SORTED                           
    JOIN UNPAIRED,F1                                                   
    REFORMAT FIELDS=(F1:1,1578,F2:1,6)                                 
    OPTION COPY                                                         
    OUTFIL IFOUTLEN=1578,                                               
      IFTHEN=(WHEN=(1584,1,CH,NE,C' '),                                 
        OVERLAY=(9:1579,6))

My job works fine with DFSORT. If you are getting syntax errors, then I suspect you are using Syncsort (WER messages), not DFSORT (ICE messages). DFSORT supports JOINKEYS syntax that Syncsort does not support.

I'm a DFSORT developer. DFSORT and Syncsort are competitive products. I'm happy to answer questions on DFSORT and DFSORT's ICETOOL, but I don't answer questions on Syncsort.
