Question

using a Oracle 10g db I have a table something like this:

 create table x(
 ID NUMBER(10) primary key,
 wedding DATE NOT NULL
 );

how can I

 select * from x where wedding is in june 2008???

I know it is probably an easy one but I couldn’t find any satisfying answer so far.
Help is very much appreciated.

Answer 1

Use:

SELECT *
  FROM x
 WHERE x.wedding BETWEEN TO_DATE('2008-JUN-01', 'YYYY-MON-DD') 
                            AND TO_DATE('2008-JUL-01', 'YYYY-MON-DD')

Use of TO_DATE constructs a date with a time portion of 00:00:00, which requires the end date to be one day ahead unless you want to use logic to correct the current date to be one second before midnight. Untested:

TO_DATE('2008-JUN-30', 'YYYY-MON-DD') + 1 - (1/(24*60*60))

That should add one day to 30-Jun-2008, and then subtract one second in order to return a final date of 30-Jun-2008 23:59.
