やっている
select distinct element from sr_queue私は得る
'c5-code-integration'
'c5-debitor-integration'
'c5-order-integration'
'c5-product-integration'
'code-dispatcher'
'fraud-protect'
'giftcard-creator'
'order-confirmation'
'packaged-confirmation'
'virtual-product-splitter'
そして、各要素に最大日付（複数あるため）を付けようとしていますが、
select element, max(added), processed
from sr_queue
where element in (
'c5-code-integration',
'c5-debitor-integration',
'c5-order-integration',
'c5-product-integration',
'code-dispatcher',
'fraud-protect',
'giftcard-creator',
'order-confirmation',
'packaged-confirmation',
'virtual-product-splitter')
選択範囲を作成するにはどうすればよいですか?
だから私は得ることができます：
order-confirmation 2013-07-03 14:12:02 2013-07-03 14:12:03
virtual-product-splitter 2013-07-03 14:12:02 2013-07-03 14:12:07
fraud-protect 2013-07-03 14:12:02 2013-07-03 14:12:11
