The following works for me. The Community table has only one entry per
community ID so it's fast to look up.
SELECT sCommunityID, (SELECT sTransactionID
FROM TransactionList
WHERE sCommunityID = Community.sCommunityID
ORDER BY sTransactionID Desc Limit 1) as MaxID
>From Community WHERE sCommunityID In ('a030600001bFi','a030600004KDy',
'a030600008QhK')
Is there any way of just supplying a list of records without having to use
another table? I know I can use parameterised queries but I would like to
be able to use a single query to get the data, as it feels like it should
be possible!
