Select records between two dates in two columns

问题:

How do I Select records between two dates in two columns?

Select * From MyTable Where 2009-09-25 is between ColumnDateFrom to ColumnDateTo

I have a date (2009-09-25) and I like to select the records that is in the timeframe ColumnDateFrom to ColumnDateTo.

Sample

Record 1 ColumnDateFrom = 2009-08-01 AND ColumnDateTo = 2009-10-01

Record 2 ColumnDateFrom = 2010-08-01 AND ColumnDateTo = 2010-10-01

If my input date is 2009-09-28; then I get record 1

Standard Between should work (T-SQL).

SELECT * FROM MyTable WHERE @MYDATE BETWEEN ColumnDateFrom AND ColumnDateFrom

    WHERE ColumnDateFrom <= '2009-09-25' AND ColumnDateTo >= '2009-09-25'

Just remove the "Is"

Select * From MyTable 
Where '2009-09-25' Between ColumnDateFrom to ColumnDateTo

remember to consider the time portiomn if the column values have date and time in them... (assuming DateOnly() is some function that strips the time from a datetime column)

Select * From MyTable 
Where '2009-09-25' Between DateOnly(ColumnDateFrom) 
                        To DateOnly(ColumnDateTo)
