Help on an Oracle Query

Posted on 2010-11-16
Last Modified: 2012-06-21
For anyone who knows Oracle this should be cake.  For me being proficient and used to SQL Server this is a complete headache that I can't figure out something that would be so easy.

I've got a table called Customer with a relevant column ExpirationDate

I need a query that will return all the records in this table where the expirationDate is less than the current date.  Or in other words, all records having an expiration data that has already passed.

This is what I have so far...
SELECT * FROM Customer

which sort of works, but I need records that have an expiration date of the current date not to show up in the query.

The expiration dates in the table are all in the form of...
16-NOV-10 12.00.00

So because SYSDATE returns a date that has a time that is later in the day than the DateTime above, that record is being included in the query.  I only want a record having an expiration date of 16-Nov to show up in this query if today's date were 17-Nov or later.

Thanks for the help.

Just noticed the other comment

SYSDATE is already a date, so TO_DATE is superfluous.  Also, the default for TRUNC is to a whole number, which is the day, so 'DD' is not required, so


is all that is required (but the first comment is not wrong)

Use the TRUNC function on SYSDATE to effectively set the time to 0000 hours, i.e. midnight. The inequality comparison in the WHERE clause will then only pick up dates prior to SYSDATE.

SELECT * FROM Customer

this query should give you the desired result
:-SELECT * FROM Customer
Trunc() function truncates the time part from date and return only the date

I'm in the habit of giving points to the first guy that has a working post and not splitting them with folks that chime in after with the same answer.  But this one was a hard call as the first answer did work but the second answer was an improvement upon.  Therefore I chose to award points as I have.

Thanks guys.
