I would like to query one table and select one customer with a specific ID (Customer A) and then obtain all the other customers from the table. The presentation order must be Customer A followed by all the other customers in order of birth date (asc). Customer A's birthdate shouuld not be included in the ordering because he needs to be at the top of the list. Any suggestions would be appreciated. Thanks!

This does not give me the correct order but shows conceptually what I am trying to get at:

Select
SESSIONID, CUSTOMERNAME, CUSTOMERID, CUSTOMERDOB
FROM CUSTOMER
WHERE CUSTOMERID = 1234567894
UNION
Select
SESSIONID, CUSTOMERNAME, CUSTOMERID, CUSTOMERDOB
FROM CUSTOMER
ORDER BY CUSTOMERDOB ASC

Select
SESSIONID, CUSTOMERNAME, CUSTOMERID, CUSTOMERDOB, 1 DUMMY
FROM CUSTOMER
WHERE CUSTOMERID = 1234567894
UNION
Select
SESSIONID, CUSTOMERNAME, CUSTOMERID, CUSTOMERDOB, 2 DUMMY
FROM CUSTOMER
ORDER BY DUMMY, CUSTOMERDOB ASC

Thank you very much Tony!

don't forget to use UNION ALL instead of UNION because there can be no dupes between the two subselects (because ot the DUMMY column)

this will save an unnecessary sort prior to the ORDER BY sort
