ORA-00937不是从SQL Server转换的单个组函数

我在运行下面的ORACLE语句时遇到一个ORA-00937错误，我对ORACLE非常陌生，T-SQL更是我的拿手好戏。我已经转换了一个以前用SQL编写的select语句，我不知道为什么它需要一个group by。。。因为所有列都是求和的。这是我目前正在使用SQLPLUS运行/测试的转换后的select语句：

select 
round(COALESCE(
(COALESCE((select SUM((F_BOOK_DATES.BKD_ADATE_ENDS - F_BOOK_DATES.BKD_ADATE_START) * (60 * 24)) FROM F_BOOK_DATES 
INNER JOIN F_BOOK_HEADER ON F_BOOK_DATES.BKD_FKEY_BK_SEQ = F_BOOK_HEADER.BK_SEQ 
and EXTRACT (YEAR from F_BOOK_DATES.BKD_DATE_START ) = EXTRACT (YEAR from SYSDATE )
and EXTRACT (MONTH from F_BOOK_DATES.BKD_DATE_START ) = EXTRACT (MONTH from SYSDATE )
and EXTRACT (DAY from F_BOOK_DATES.BKD_DATE_START ) = EXTRACT (DAY from SYSDATE )
AND F_BOOK_HEADER.BK_STATUS NOT IN ('CX','TP')
AND F_BOOK_HEADER.Deleted <> 1
AND F_BOOK_DATES.Deleted <> 1),9999999999.99,0)
/sum(case when FAREALO.AllDayBooking = 1 then 1400 else
((FAREALO.LO_TIME_END - FAREALO.LO_TIME_START) * (60 * 24)) end) * 100),0),2) as "PercentUtilised"
from FAREALO
inner join F_LO_TYPE on FAREALO.LO_FKEY_LOT_SEQ = F_LO_TYPE.LOT_SEQ
where FAREALO.LO_BK_LOCATION = 1
and LOT_CBS = 1;

这是我在上面尝试转换的SQL语句：

select 
round(isnull(
(isnull(convert (DECIMAL(10,2),(select SUM(datediff(n,BKD_ADATE_START, BKD_ADATE_ENDS)) FROM F_BOOK_DATES with (NOLOCK) 
INNER JOIN F_BOOK_HEADER with (NOLOCK) ON BKD_FKEY_BK_SEQ = BK_SEQ 
AND DATEPART(YYYY,BKD_DATE_START) = DATEPART(YYYY,GETDATE())
AND DATEPART(MM,BKD_DATE_START) = DATEPART(MM,GETDATE())
AND DATEPART(DD,BKD_DATE_START) = DATEPART(DD,GETDATE())
AND BK_STATUS NOT IN ('CX','TP')
AND F_BOOK_HEADER.Deleted <> 1
AND F_BOOK_DATES.Deleted <> 1)),0)
/
sum(case when AllDayBooking = 1 then 1400 else
datediff(n,LO_TIME_START, LO_TIME_END) end) * 100),0),2) as PercentUtilised
from FAREALO with (NOLOCK)
inner join F_LO_TYPE with (NOLOCK) on LO_FKEY_LOT_SEQ = LOT_SEQ
where LO_BK_LOCATION = 1
and LOT_CBS = 1

有人看到我错过了什么吗

谢谢

在添加MIN函数后，修改后的查询运行良好：

select 
round(COALESCE(
(COALESCE(MIN((select SUM((BKD_ADATE_ENDS - BKD_ADATE_START) * (60 * 24)) FROM F_BOOK_DATES 
INNER JOIN F_BOOK_HEADER ON BKD_FKEY_BK_SEQ = BK_SEQ 
and EXTRACT (YEAR from BKD_DATE_START ) = EXTRACT (YEAR from SYSDATE )
and EXTRACT (MONTH from BKD_DATE_START ) = EXTRACT (MONTH from SYSDATE )
and EXTRACT (DAY from BKD_DATE_START ) = EXTRACT (DAY from SYSDATE )
AND BK_STATUS NOT IN ('CX','TP')
AND F_BOOK_HEADER.Deleted <> 1
AND F_BOOK_DATES.Deleted <> 1)),9999999999.99,0)
/sum(case when AllDayBooking = 1 then 1400 else
((LO_TIME_END - LO_TIME_START) * (60 * 24)) end) * 100),0),2) as "PercentUtilised"
from FAREALO
inner join F_LO_TYPE on LO_FKEY_LOT_SEQ = LOT_SEQ
where LO_BK_LOCATION = 1
and LOT_CBS = 1;

是否可以编辑您的问题以包含表格定义？我不知道哪些列属于哪些表。此外，如果您使用查询中的所有列来自的表来标识它们，例如，不写BK_STATUS、写F_BOOK_HEADER.BK_STATUS等等，这是否有帮助？我已在上述Oracle查询中添加了完整的表def。虽然已将MIN添加到sum第3行的第一部分，但由于该部分多次返回相同的值，因此查询现在运行
