351 days = 50 1/7 weeks
352 days = 50 2/2 weeks
I have a column with days in it.How do i represent it in weeks / days in the select statement output.

#days / 7 = #wks

#days % 7 = #days

pls try below code:

declare @days int=350

select convert(varchar(10),(@days/7))+' '+case when (@days-((@days/7)*7))=0 then '' else convert(varchar(10),(@days-((@days/7)*7)))+'/7' end

I got this part.How do i concatenate both weeks and days together.

Ex: 37 5/7 or 31 /2/7 or 41 6/7

I have a days column

Ex:280 days

I would like to represent it as 40 0/7 in another column

281 will be 40 1/7

288 will be 41 1/7

All this has to be part of a select statement.

select col1,col2 ,days,weekdays from table1;

days column will have days

weekdays must have this information 40 0/7 , 40 0/7 , 40 0/7

Output must be :

Days , weekdays

280 40 0/7

281 40 1/7

288 41 1/7

How do i do this

thanks

SELECT

col1, col2, days,

CAST(days / 7 AS varchar(5)) + ' ' + CAST(days % 7 AS varchar(1)) + '/7' AS weekdays

FROM dbo.tablename

Just double checking... you want "0 1/7" for 1 day and not "1 1/7" or "0 0/7", correct? If so, Scott's code works a treat.

I ask mostly because the first "week" will only have 6 days. The 7th day will be "1 0/7" as currently defined.

I don't see that as the first "week" having only 6 days. The "1" full week indicates 7 days.

6 days would result in "0 6/7", which mean 6 days of the first week, but no full week yet, i.e. less than 7 days.

Yep... that's exactly what I was talking about.
