How can I get the Lastest record from SQL

MS Access
I have a table like this: balance keepplace startdate ___________________________________ A01 floor 1 2002-10-10 A01 BBB 2001-08-08 A02 222 2002-07-08 A02 111 2000-01-01 A03 .... I want to get " where is the keep place for all balance by now? Answer Use a sub-select to get the last date - and make that match the original...	CREATE TABLE placement(balance CHAR(3) ,keepplace VARCHAR(10) ,startdate DATE ,PRIMARY KEY(balance,startdate) ); INSERT INTO placement VALUES('A01','floor 1','10 Oct 2002'); INSERT INTO placement VALUES('A01','BBB','08 Aug 2002'); INSERT INTO placement VALUES('A02','222','08 Jun 2002'); INSERT INTO placement VALUES('A02','111','01 Jan 2002'); SELECT balance, keepplace, startdate FROM placement, ( SELECT balance AS B, MAX(startdate) AS S FROM placement GROUP BY balance) X WHERE startdate = X.S
