方法 1:
try:
select
count(page) as TARIH
,(datepart(hour,Date)*60+datepart(minute,Date))/@countgap as SIRA
from scr_SecuristLog
where Date between @date1 and @date2 and (Page=@page or Page = AllDATA)
方法 2:
Solution: select count(page) as TARIH, (datepart(hour,Date)*60+datepart(minute,Date))/@countgap as SIRA from scr_SecuristLog where Date between @date1 and @date2 and (Page=@page or @page='Tüm Kullanıcılar')
方法 3:
select count(page) as TARIH,
(datepart(hour,Date)*60+datepart(minute,Date))/@countgap as SIRA
from scr_SecuristLog
where
Date between @date1 and @date2
and
(
(@page is not null and Page=@page)
or (@page is null and @page=@page)
)
will return all data between date1 and date2 and only data equal to the parameter, or if the parameter is null will return all data between date1 and date2
