Hi Friends,
I used DSNUTILB program to extract a DB2 table. The extract file is in VB format with length 302. Acc to the DCLGen, the length of the table is 296 bytes. To convert it into FB, i used the following logic in DFSort:
| Code: |
//STEP20 EXEC PGM=SORT
//SORTIN DD DSN=USERID.DB2TBL.EXTRACT,
// DISP=SHR
//OUTPFIL DD DSN=USERID.DB2TBL.EXTRACT.FB,
// DISP=(NEW,CATLG,DELETE),
// SPACE=(TRK,(10,10),RLSE),
// UNIT=DISK
//SYSIN DD *
SORT FIELDS=COPY
OUTFIL VTOF,FNAMES=OUTPFIL,VLFILL=C' ',
OUTREC=(1:5,296)
//TOOLMSG DD SYSOUT=*
//DFSMSG DD SYSOUT=*
//SYSOUT DD SYSOUT=* |
As in any VB file, first 4 bytes are RDW, and data starts from the 5th byte, i used OUTREC=(1:5,296).
But i am getting 2 extraneous characters(..) in the beginning of each record and the whole record is shifted to the right by these 2 characters.
Later when i used OUTREC=(1:7,296) the output was correct. Can anybody explain why use 7 and not 5 as the starting position as used for any VB file.
Thanks,
Asif. |

I also used the following code but got the same first characters(..) and whole record got shifted right
| Code: |
//STEP10 EXEC PGM=ICEGENER
//SYSIN DD *
GENERATE MAXFLDS=1
RECORD FIELD=(296,1,,1)
/*
//SYSPRINT DD SYSOUT=*
//SYSUT1 DD DSN=USERID.DB2TBL.EXTRACT,DISP=SHR
//SYSUT2 DD DSN=USERID.DB2TBL.EXTRACT.FB,
// DISP=(NEW,CATLG,DELETE),
// DCB=(RECFM=FB,LRECL=296),
// SPACE=(CYL,(1,1),RLSE),UNIT=SYSDA

| How about a hex display of the front part of both a VB and an FB record? |

4 for the RDW and probably 2 for the first column which is varchar?
if you don't want any more guesses, provide us with the select statement and the table def. |

vasif,
You don't even have to convert from VB to FB. Take a look at your SYSPUNCH dd from your unload step , It will list all the columns which are null and varchar columns with positions. You can use the functions IFNULL, VALUE, COALESCE to have default values for them. For VARCHAR fields use the function CHAR to make them char data. By doing this you can avoid the conversion of the file from VB to FB |
