Thanks for your reply Rob
In answer to your question of "Who cares?" the answer is ---Me
You are correct, there are other columns in this file, but I only mentioned
the columns that I need to deal with for this situation
I'm trying to get a test file, where the 2 record types are mingled so that
I can test another set of programs
The mingle will be what is happening when we go live

So let's say your data contains only two columns: RECID and TS. And your
sample data is:
A 2010-08-09-08:01:35.00000
A 2010-08-09-08:01:35.00000
A 2010-08-09-08:01:35.00000
A 2010-08-09-08:01:35.00000
A 2010-08-09-08:01:35.00000
A 2010-08-09-08:01:35.00000
B 2010-08-09-08:01:35.00000
B 2010-08-09-08:01:35.00000
B 2010-08-09-08:01:35.00000
B 2010-08-09-08:01:35.00000
B 2010-08-09-08:01:35.00000
B 2010-08-09-08:01:35.00000
And you want:
A 2010-08-09-08:01:35.00000
B 2010-08-09-08:01:35.00000
A 2010-08-09-08:01:35.00000
B 2010-08-09-08:01:35.00000
A 2010-08-09-08:01:35.00000
B 2010-08-09-08:01:35.00000
A 2010-08-09-08:01:35.00000
B 2010-08-09-08:01:35.00000
A 2010-08-09-08:01:35.00000
B 2010-08-09-08:01:35.00000
A 2010-08-09-08:01:35.00000
B 2010-08-09-08:01:35.00000
My question is: Who cares? What possible business reason is there?
Perhaps there must be some additional columns to consider?
But if there truly is some need then you could use that function that uses
scratchpad to create a row_number and sort by the A/B column and that
row_number.

As soon as I pressed Enter, I wasn't too sure that I had explained myself
So here is my second attempt
The file contains 1,000 records, by timestamp, but as it happens, the
first
500 are record types A and the second 500 are record types B (by
timestamp)
I need to change the timestamp so that the 2 types are mingled
A
B
A
B
A
B
by timestamp
Hopefully that makes it a little clearer
Again, thanks in advance

Morning all
sorry about the subject line, but I couldn't think of a better one
Here is my predicament
I have a test file with thousands of records, but basically 2 types
Record type A
Record type B
The key to this file is a timestamp field, however, the file is basically
one batch of record type A, followed by a batch of record type B (based on
timestamp)
How can I "mix/mingle" these types so that the sequence (by timestamp) is
A
B
A
B
A
it can be a group of A, a group of B, a group of A, a group of B
As long as there is a mixture
I've thought about this all morning to no avail, so if someone has any
ideas , it would be MUCH appreciated
Thanks in advance
