Question

I have a few sql statements where I manually enter the date everyday then execute.

I would like to automate the date part. But weekends are giving me trouble. I use excel to run the reports as it is then saved and another member of staff does a mailshot.

This is my test example:

if (datename(dw, getdate()) = 'Friday') BEGIN
select convert(varchar, dateadd(day, 7, DATEADD(dd, 0, DATEDIFF(dd, 0,getdate()))), 103)
 + ',' + convert(varchar, dateadd(day, 9, DATEADD(dd, 0, DATEDIFF(dd, 0,getdate()))), 103) AS [Date] END
ELSE BEGIN select convert(varchar, dateadd(day, 7, DATEADD(dd, 0, DATEDIFF(dd, 0,getdate()))), 103) as [Date] END;

But how would I put this into a sql where statement?

for example

select * from table where (date = )

where Date equals 7 days in advance unless It’s Friday when we have to account for the weekend so we want 7,8 and 9 days in advance?

Answer 1

select * from table where date = (case
  when datename(dw, getdate()) = 'Friday' then
    convert(varchar, dateadd(day, 7, DATEADD(dd, 0, DATEDIFF(dd, 0,getdate()))), 103)
     + ',' + convert(varchar, dateadd(day, 9, DATEADD(dd, 0, DATEDIFF(dd, 0,getdate()))), 103)
  else
    convert(varchar, dateadd(day, 7, DATEADD(dd, 0, DATEDIFF(dd, 0,getdate()))), 103)
  end)
