Question

查询给了我一些错误：

第15行，第1行，第4行关键字'from'附近的语法不正确。 Msg 156，Level 15，State 1，Line 9 关键字“group”附近的语法不正确。

select 
Count(Page) as VisitingCount,
dbo.fn_GetActivityLogsArranger(CONVERT(VARCHAR(5),Date, 108)as [Time] 
 from scr_SecuristLog     
where Date between '2009-04-30' and '2009-05-02'    
and [user] in(select USERNAME               
    from scr_CustomerAuthorities 
where customerID=Convert(varchar,4) and ID=Convert(varchar,43) )    
group by CONVERT(VARCHAR(5),Date, 108) order by CONVERT(VARCHAR(5),Date, 108) asc 
------------------------------------------------------------------------------------------------------
create FUNCTION [dbo].[fn_GetActivityLogsArranger]
(
@time AS nvarchar(max)
)

RETURNS  nvarchar(max)
AS

select @Return = case 
when @time between '15:00' and '15:30' then '15:00-15:30'

when @time between '17:00' and '17:30' then '17:00-17:30' 
when @time between '17:30' and '18:00' then '17:30-18:00'
else 'Unknown'
end
 Return @Return
end

你错过了一个括号

select 
Count(Page) as VisitingCount,
dbo.fn_GetActivityLogsArranger(CONVERT(VARCHAR(5),Date, 108)**)** as [Time] 
 from scr_SecuristLog     
where Date between '2009-04-30' and '2009-05-02'    
and [user] in(select USERNAME               
    from scr_CustomerAuthorities 
where customerID=Convert(varchar,4) and ID=Convert(varchar,43) )    
group by CONVERT(VARCHAR(5),Date, 108) order by CONVERT(VARCHAR(5),Date, 108) asc
