I am using MSSQL 2000.
I have a table with a date column containing dates, t_mydates(dateA).
I have a second table t_exlusions(start_date,end_date)
I want a query which returns all dates from t_mydates where they are not between any of the rang开发者_C百科es in t_exlusions.
Query:
select d.*
from @t_mydates d
left join @t_exlusions e on date between start_date and end_date
where start_date is null and end_date is null
Test date:
declare @t_mydates table (date date)
insert into @t_mydates (date)
values
(GETDATE()),(GETDATE()-1),(GETDATE()-2),(GETDATE()-3),(GETDATE()-4),(GETDATE()-5),(GETDATE()-6),(GETDATE()-7)
declare @t_exlusions table (start_date date, end_date date)
insert into @t_exlusions (start_date, end_date)
values
(GETDATE()-1, GETDATE()), (GETDATE()-5, GETDATE()-4)
Result:
2011-08-27
2011-08-26
2011-08-23
2011-08-22
