Hi. I have a field 'Quantity' that is of data type DECIMAL (17,5). It holds a value or time in minutes.
I would like to display this as hours.
Would I use CAST / CONVERT within the SELECT or declare a variable?
DECLARE @TimeBooking decimal (17,5)
SET @TimeBooking = ??
so:
SELECT Id,P.PId,Users.FirstName + ' ' + Users.LastName AS UserName,LT.Quantity
FROM MyTables
Many Thanks,
Phil.

If you have minutes, then divide by 60 for the hours and mod 60 for the minutes left on the remaining hour... Though, what does your minutes look like with five decimals..?

selectquantity / 60 as hours,

quantity % 60 as minutes

from .....

So that means that the quantity column isn't correctly typed then, since the number of minutes doesn't have any fractions..

Still, divide the minutes by 60 and mod by 60 for the minutes in the remaining hour...

Is that what you're looking for?

Hi Kenneth. What do you mean by mod by minutes?

I implemened as:

LT.Quantity / 60 AS Hours

Many Thanks,

Phil.

I think he is refering to

LT.Quantity % 60 AS Minutes

So if your quantity as 72 you could have

Hours Minutes

1 12

Sorry for the late reply, but yes, that's precisely what I ment. 🙂

/ 60 for the full hour, and % 60 if you want the remaining minutes

Hello again. So how would the full code read to get 1 Hour 10 minutes?

I have:

LT.Quantity / 60 AS Hours

Many Thanks,

Phil.

SELECT

Case

When LT.Quantity/60 = 1 Then

Convert(nvarchar(10),LT.Quantity/60) +' Hour'

Else Convert(nvarchar(10),LT.Quantity/60) +' Hours'

End + ' ' +

Case

When LT.Quantity%60 = 1 Then

Convert(nvarchar(2),LT.Quantity%60)+' Minute'

Else Convert(nvarchar(2),LT.Quantity%60)+' Minutes'

End As [Time]

I only have a case statement to handle the pural of the word hour or minutes, as saying 1 hours doesn't sound as nice as saying 1 hour.

Chris poor explanation on my part. If the user enters 8 in the hours field then enters 15 in the minutes field this is recorded as 75:00000.

Many thanks for the explanation Phil, had me scratching me head for hours! It all makes sense now.

Cheers

Ok, I'm completely confused... The last time I checked, 8 hours and 15 minutes is a total of 495 minutes, not 75. If the user enters 1 for the hours field and 15 in the minutes field, THEN you could come up with 75:00000 as a result, but I'm even confused by the presence of the ":", as a decimal number should be using a decimal point as opposed to a colon, right? (or is this a non-US environment?)

OK, having a blonde moment, what I should have posted was 1 hour 15 minutes = 75 🙂

Many Thanks,

Phil.
