Perhaps try "EXPLAIN ANALYZE" on this query, given a valid event ID:
SELECT Distinct Companies.Name
FROM Companies INNER JOIN
ExpenseAllocations ON Companies.ID =
ExpenseAllocations.BusinessUnitID
WHERE (ExpenseAllocations.EventID =
@EventID)
ORDER BY Companies.Name DESC
#######
Do the columns used in the join and WHERE clause have indexes?
It's also possible the optimization needs to happen at a different level.
Perhaps you are frequently
looking up the same results in a large report, or throughout the day.
If this part doesn't need to be up-to-second fresh, perhaps your application
could
cache some of the results of this function, instead of repeatedly asking the
database
to recompute it.
