A small problem was encountered when making SSRS. The user requested to select the data of the report 24 hours a day. Take 0 ~ 23 from master..spt_values, but 0 ~ 9 is not a normal time point of the system, and needs to be changed after 00 ~ 09, there are several ways to achieve the following.
method one:
select right (cast('0'+cast( number as nvarchar(2)) as nvarchar(3)),2)
from master..spt_values
where type='p' and number between 1 and 24
方法二：
select case when number <10
then '0'+ cast(number as varchar(50) )
else
cast(number as varchar(20))
end
from master..spt_values
where type='P'
and number<24
方法三：
select replicate('0',2-len(number))+convert(varchar(10),number)from master..spt_values where type='P'
replicate: repeat the character expression the specified number of times
After the parameters are defined in this way, you can press 00 ~ 23 to select and view 24 or 24 times a day.
