このMySQLステートメントをMS SQLに変換してSQL 2008 R2で実行するのを手伝ってくれる人はいますか?

SELECT UNIX_TIMESTAMP(summary.date) as epoch_date,
round(SUM(CASE WHEN meters.group != '' THEN kWh ELSE 0 END),2) as total,
round(SUM(CASE WHEN meters.group = 'eastern' THEN kWh ELSE 0 END),2) as eastern,
round(SUM(CASE WHEN meters.group = 'western' THEN kWh ELSE 0 END),2) as western,
round(SUM(CASE WHEN meters.group = 'central' THEN kWh ELSE 0 END),2) as central
FROM summary, meters
WHERE summary.webmeterID = meters.webmeterID
AND date BETWEEN
DATE_SUB(CURRENT_DATE, INTERVAL 3 YEAR) 
AND DATE_SUB(CURRENT_DATE, INTERVAL 1 DAY)
GROUP by date
