Re: Remove duplicate records

Hi John
this web page may give you a start as to how to delete the records in
question using SQL
The "unfortunate" thing here is that this is a join logical, so (I believe)
you cannot delete the records in question from this join

Good luck

I made a mistake today. Accidentally ran a posting program three
additional times. I normally try to automate things so dumb things
like thisdon't happen. But, this has not been a project developed
in the proper manner - meaning GET IT DONE!

The file is a join logical. Common ields are 1) hospital number, 2)
account, 3) date, 4) time , and 5) id of poster. The first four
fields are numeric and the last is alpha.

The two files are a main file with 30 characters of text and the
second file contains multiple records for additional text.

Something like 5000 records posted three extra times..

The problem will disappear in about 6 months, if nothing is done.
Just looks bad and a lot of people will see my blunder and have to
deal with it.

Can SQL be used to identify when there are multiple records for the
same hospital and account number that have identical date, time,

andposter id?

Can SQL be used to remove three of the four multiples?

Can SQL be used to do the previous two operations, but for one
specific account - for testing?

Would it be easier if the original posting file was available? My
assumption is yes. and that file can be available.


This doesn't effect any totals. Just looks really bad.


Seems this would be pretty simple in RPG, especially with the
original file available. Just don't know if I can get the time to
devote to tis.

Is this something a) best left alone, b) best fixed with SQL, or c)
best fixed with RPG?


Easiest approach would be to back out all the records and ten post
once, I am guessing.


Wish I hadn't made the mess, in any case.
