放置where子句时MS SQL查询不工作

我正在编写一个简单的查询来获取特定日期的金额。如果没有where子句，查询运行良好。但在放入where子句之后，它不会获取任何记录。请帮忙

我的问题是

Select 
OSTotal as RevenueDaily,
systemlastedittime as Lastedittime
from AccTransactionHeader where systemlastedittime = '09/02/2015'

---

另外，

systemlastedittime

的数据类型是

DT

，我不知道它的格式是

ddmmyyyy

还是

mmddyyyy

格式。

格式应该是

yyyyy-MM-dd

Select OSTotal as RevenueDaily, systemlastedittime as
 Lastedittime from AccTransactionHeader where
 CAST(systemlastedittime as DATE) ='2015-02-09'

---

格式应为

yyyy-MM-dd

Select OSTotal as RevenueDaily, systemlastedittime as
 Lastedittime from AccTransactionHeader where
 CAST(systemlastedittime as DATE) ='2015-02-09'

---

格式应为

yyyy-MM-dd

Select OSTotal as RevenueDaily, systemlastedittime as
 Lastedittime from AccTransactionHeader where
 CAST(systemlastedittime as DATE) ='2015-02-09'

---

格式应为

yyyy-MM-dd

Select OSTotal as RevenueDaily, systemlastedittime as
 Lastedittime from AccTransactionHeader where
 CAST(systemlastedittime as DATE) ='2015-02-09'

你也可以试试

set dateformat ymd

在select语句之前。 摘自MSDN，您也可以尝试

set dateformat ymd

在select语句之前。 摘自MSDN，您也可以尝试

set dateformat ymd

在select语句之前。 摘自MSDN，您也可以尝试

set dateformat ymd

在select语句之前。 以下查询摘自MSDN：

Select OSTotal as RevenueDaily, systemlastedittime as Lastedittime 
from AccTransactionHeader 
where CAST(systemlastedittime AS DATE)= '2/9/2015'

以下是查询：

Select OSTotal as RevenueDaily, systemlastedittime as Lastedittime 
from AccTransactionHeader 
where CAST(systemlastedittime AS DATE)= '2/9/2015'

以下是查询：

Select OSTotal as RevenueDaily, systemlastedittime as Lastedittime 
from AccTransactionHeader 
where CAST(systemlastedittime AS DATE)= '2/9/2015'

以下是查询：

Select OSTotal as RevenueDaily, systemlastedittime as Lastedittime 
from AccTransactionHeader 
where CAST(systemlastedittime AS DATE)= '2/9/2015'
