Re: Best Way to find duplicate records in same file

I'd pick some logical file, any logical file, for that physical, so long as
it included all fields.
 
I'd define a data structure externally.  I'd define a field New data 
Like(The Data Structure) and eval it as equal to the new record..
 
Then I would use the key to do setll/read loop while the key is unchanged.
 
In the loop if the datastructure equals the new data field, then I'd process
my duplicate record subroutine.

Subject: Best Way to find duplicate records in same file
 
I need to add duplicate record checking in a file we received from a
switch. (I'll just add it to the CL that already FIXES a bunch of stuff
in the file anyways) and was wondering what the best (i.e easy/fast) to
do it would be. I've come up with:
 
1. Run a query against the file, sorted by entire record, level break
on entire record, count. Output Query results to file and then do cpyf.
2. Build a file keyed on all 210 bytes, read original chain to new
file, if not found write it
3. SQL ??? not done much with it but maybe it could do?
