Hello all,
I have a table - PlantHistory - with 2 datetime fields, like:


PlantStartDate - PlantEndDate

2000-01-01 00:00:00 2099-12-31 23:59:59
2002-01-01 00:00:00 2009-12-31 23:59:59
...


Then I have stored procedure that has 2 datetime parameters, RefStartDate - RefEndDate.


Now I have to extract from PlantHistory table only the record that has at least one second
of the fields PlantStartDate and PlantEndDate
"inside" my RefStartDate and RefEndDate parameters.


How can I write this WHERE clause?
