Re: Missing numbers ( was Re: )

Hello, David:

Try to use the "KISS" principle ("Keep It Super Simple!")

I think a simple solution could be:

1. create a table of available numbers
   (a) use a batch program to initially load the "available numbers" 
table,
        with one sequential pass over the actual target table(s)

2. To allocate the next available number in your application(s):
   (a) "pull" (SETLL, READ with record lock) the next available number 
from "available" table
   (b)  immediately DELETE that number from "available" table (releases 
record lock)
   (c)  use this number just obtained to insert into the actual target 
table(s). 

3. Periodically monitor how many numbers are available in each category, 
e.g.:
               SELECT COUNT(*) FROM availNbrs WHERE category = 'TX'
          so you know when it is time to increase the size of those 
numbers in the tables

Albert Einstein said, "Make it as simple as possible, but not simpler."
