Display Two columns at the same time using Cross Apply-CodePudding

I have pretty much the same logic on the bottom but I am not able to put together to display two columns.

I am not sure how to combine two Cross Apply queries into one.

select


DateAdd(hour,hour_diff, ps)   punch_start
from [dbo].[Stage]
cross apply
(
values
( Try_Convert(datetime, punch_start) )
) x
(ps)
left join 
[dbo].[DIM] d on ps between d.start_dt and  d.end_dt

,
DateAdd(hour,hour_diff, ps1)  punch_end
from [dbo].[Stage]
cross apply
(
values
( Try_Convert(datetime, punch_end) )
) y
(ps1)
left join 
[dbo].[DIM] d on ps1 between d.start_dt and  d.end_dt

CodePudding user response：

If I understand correctly, you can try combining two-column in VALUES

SELECT
    DateAdd(hour,hour_diff, ps)  punch_start,
    DateAdd(hour,hour_diff, ps1)  punch_end
FROM [dbo].[Stage]
CROSS APPLY
(
    values (Try_Convert(datetime, punch_start),Try_Convert(datetime, punch_end))
) x (ps,ps1)
left join 
[dbo].[DIM] d on 
    ps between d.start_dt and  d.end_dt
OR 
    ps1 between d.start_dt and  d.end_dt
