Re: Using SQL to "mix" the records in a file

[Alan Shore <AlanShore@xxxxxxxx>]

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
