| HI,There is a folder on the network that has about 300 subfolders. These subfolders are dates going back to last year.There is supposed to be one file (date) per day except sundays.I have run a program which inserted these dates into a table.So now I have the name of these subfolders (dates) in a table.The question is, how can I find out which days are missing from this list except sundays.Remember, there should be a file per day.Thanks |

| [code]SELECT *FROM MyTable T1WHERE DATEDIFF(Day, ( -- Most recent preceeding day SELECT MAX(T2.MyDate) FROM MyTable T2 WHERE T2.MyDate < CASE WHEN DATEPART(WeekDay, T1.MyDate) = 2 -- If testing against a Monday then base on Sunday THEN DATEADD(Day, -1, T1.MyDate) ELSE T1.MyDate END ), T1.MyDate) > 1 - More than 1 day difference?[/code]Kristen |
