Select Date Between Two Columns

Question

I need a query in SQL.
If I have two columns STARTDATE and END_DATE.
I want to select a all rows where a date falls between these two dates.

e.g.: startdate = 1/1/2011 AND enddate = 2/2/2011.

Answer 1

SELECT * FROM table1 
WHERE '2011-01-01' BETWEEN table1.startdate AND table1.enddate

Replace the explicit date either with now() or a parameter or whatever.

If the enddate is not defined as NOT NULL you can do:

SELECT * FROM table1 
WHERE '2011-01-01' BETWEEN table1.startdate AND COALESCE(table1.enddate, NOW())

See: http://www.1keydata.com/sql/sql-coalesce.html

Answer 2

Does this help you ?

select * 
from table 
where START_DATE < NOW() AND END_DATE > NOW()

Depending on the database, use CURRENT_TIMESTAMP() or TODAY()
