[thelist] Tables referencing each other

[Anthony Baratta]

Bill...

Another way is to cheat and use your profile table ID.

Select Top 1 * from Profile
where cust = 67
order by id DESC;
(MS SQL)

Select * from Profile
where cust = 67 and rownum = 1
order by id DESC;
(ORACLE)

Select * from Profile
where cust = 67
order by id DESC
limit 1;
(mySQL)

This way you don't have the deal with a current flag at all. The last 
profile entered for a customer should be the "most current" one.

You can create a view to return only the most current profile for each 
customer and select against by Cust ID that instead.

Also, you can carry the profile table ID into your order table, and that 
will link to the current profile at the time of the customer order.
