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

Alan,
If the 'A' and 'B' records do not have the same key value, do they have any
other fields in common that could be used to sort them?

Thanks,

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


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
