访问SELECT X天前的字段

Question

This query appears to be returning ALL rows and not just those more than 3 days old (ie the date in Created On field)

SELECT * FROM Master WHERE [Created On] < (Date()-3);

I don't see what is wrong with it.

EDIT - this worked as expected (sorry my question was badly worded)

SELECT * FROM Master WHERE [Created On] > (Date()-3);

Just changed the < to > ie all records that are more recent than 3 days ago.

Answer 1

I reproduced your SELECT command and it's apparently correct. In my case the query worked perfect. Try to execute this select to see the result of the (Date() -3) from three days ago. For example:

SELECT Date(), Date() -3, *
FROM Master
WHERE [Created On]<(Date()-3);
