對於我的項目,我們使用的是MS SQL 2008.在子查詢中,我喜歡在WHERE子句中搜索當前(在SQL循環中)年的最後一天。它應該是這樣的:SQL WHERE date部分字段和部分預定義字符串
WHERE datefieldsubquery = currentyearparentquery+'-12-31 23:59:00'
但是在使用這個時子查詢中沒有輸出。當查詢是例如:
WHERE datefieldsubquery = '2014-12-31 23:59:00'
查詢返回結果。我喜歡'2014'是從父查詢動態繼承的。這在SQL中可能嗎?
- 編輯 - 這兩個字段都是日期時間。
真實完整的查詢:
SELECT factuurregel.[Internal costkind] AS code,
COUNT(factuurregel.[Internal costkind]) AS total,
YEAR(factuurregel.[Invoice date lease company]) AS maand,
(
SELECT COUNT(leasecontract.[Contract Ending Date]) AS autos
FROM [test$Lease Contract] AS leasecontract
WHERE (leasecontract.[Status] = '0' OR leasecontract.[Status] = '1')
AND YEAR(leasecontract.[Contract Activation Date]) <= YEAR(factuurregel.[Invoice date lease company])
AND (YEAR(leasecontract.[Contract Ending Date]) > YEAR(factuurregel.[Invoice date lease company])
OR leasecontract.[Contract Ending Date] = '1753-01-01 00:00:00')
) AS autos
FROM [test$Invoice line] AS factuurregel
LEFT JOIN [test$Lease Car] AS leasecar ON factuurregel.[License No_] = leasecar.[License No_]
WHERE factuurregel.[Internal costkind] >= '200'
AND factuurregel.[Internal costkind] < '300'
AND (leasecar.[Licence Type] = 1 OR leasecar.[Licence Type] = 2)
GROUP BY YEAR(factuurregel.[Invoice date lease company]),factuurregel.[Internal costkind]
ORDER BY factuurregel.[Internal costkind]
怎麼樣嘗試這種方式'WHERE年(datefieldsubquery)

你的數據類型是什麼? datefieldsubquery是日期嗎?約會時間? VARCHAR? currentyearparentquery是一個整數嗎? VARCHAR?你問的是可能的,但我們需要更多的細節來幫助你。 – 2014-08-27 11:52:11
什麼是currentyearparentquery在您的查詢? – 2014-08-27 11:55:02
