i am sorry this is SQL question, but i could not find an appropriate section, so i post here
my question is
i need to pull something like
select convert(char(12), datetime,101), sum(...) as A, sum(...) as B
where case when condition1 then datepart(hh, datetime) between 8 and 18(which i want to pull the data between 8am to 18pm) when condition 2 then 'pull the data between 7am to 20pm end
how to write this where clause? i tried to write
where case when condition1 then datepart(hh, datetime) between 8 and 18 end, but it is wrong
do someone know?
