Which table you are talking about?
Is that OCCURS clause or DB2 Table or something else...? |

Here is the very basic flow.
| Code: |
open output file
OPEN cursor
FETCH a row
perform until sqlcode not = 0
write a record
fetch a row
end-perform.
close cursor
close output file. |
[/code] |

Seems like overkill to write a program to put a table to a file, unless of course you are doing processing on the data before writing the data to the file.
DFSORT and SYNCSORT can both do this. However, I believe the DB2 unload utility is far more efficient than any of these. |

Hi,

I guess there is no need of OCCURS class to write a VSAM file, Because you are using FETCH cursor stament of DB2, Which reads DB2 record sequentially and write one by one in to the flat file.
What made you to think to use OCCURS class?
Tell us the scenario. |

You cannot use an OCCURS to fetch data form a database.
If you explain what you "have" and what you want to do, someone here will be able to help. Show input data and desired "output" even if the output is internal to a program. |
