This code assumes the tables are correlated by [CustomerID] and the transaction table has a [transactionDate] column and that is what determines the "last" transaction:


select c.*
       ,oa.*
from   customers c
outer apply (
       select top 1 * 
       from customerTransactions
       where customerid = c.customerid
       order by trasactionDate desc
       ) oa

EDIT:
and you should replace the "SELECT *"s with explicit column lists
