Re: Splitting a big file into smaller files

Hi Darryl,

You'd have to show me your statement if you want any help to figure out why
you have an error.

These two work for me after changing the schema and table names to
something valid. Check if you are using '.' or '/' between your schema and
table name.

with t1 as (

select row_number() over(order by RRN(a) ) as row_number, RRN(a) as RRN, a.*

from schema.table a)

select *

from t1

where row_number <> RRN ;



with t1 as (

select row_number() over(order by RRN(a) ) as row_number, a.*

from schema.table a)

select *

from t1

where row_number between 1 and 10000 ;

I get a ) error running the command.

The files are all created so re-use is yes.

It looks like splitting the file is dropping records.

Hi Darryl,

Using the DELETE command doesn't necessarily mean the system will do a

FAST

DELETE, a.k.a. RGZPFM. It might just delete all the records. Resetting
the RRN will then depend on whether you have REUSE DELETED RECORDS. If

you

DSPFD on the table, what does it show for REUSE DELETED RECORDS and TOTAL
DELETED RECORDS?

The big file was cleared before writing to it using the delete command.

Subject: Splitting a big file into smaller files

I am splitting large files of 400,000 plus records into files of 10,000

each.

I am using SQL to create the records using the create table command. I

split the file using

FROM RRN(A) between 1 and 10,000

FROM RRN(A) between 10,001 and 20,000

FROM RRN(A) between 20,001 and 30,000

.



Problem:

Why would the system not copy exactly 10,000 records. I have several

files that have a few records less than the 10,000 I should have in each
file.

Has anyone seen this problem before?

If you have, what is the reason?



This is a V5R4 system.



TIA
