I need to find a value for each nodename where the time is maximun for each nodename. Its an access passthrough query to MYSQL.
Three tables: nodes, variables and variablelog. Any suggestions for altering the code below?

SELECT nodes.nodeName, variables.varName, variablelog.value, from_unixtime(variablelog.time)
FROM variablelog LEFT JOIN (variables LEFT JOIN nodes ON variables.nodeId = nodes.nodeId) ON variablelog.varId = variables.varId
WHERE variablelog.time > (UNIX_TIMESTAMP() - 400200)
ORDER BY nodes.nodename DESC;
