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

[Loyd Goodbar <loyd@xxxxxxxxxxxxxx>]

If using SQL, try:
select timestampfield, recordtypefield from file order by 1, 2;
In the case of duplicate timestamp IDs, the record type (if A or B) will be
sorted.
If needed, you can use a CASE statement to derive the record type if it is
based on something unique in each record.

Thanks,
Loyd
