Comparing dates stored as varchar

Question

I need to compare dates that are stored in my database as varchar against today\'s date.

Specifically, I need to exclude any records with a date that has passed.

Answer 1

Other than what people have already suggested that you should never store DATETIME as VARCHAR. Always store it in a DATETIME type column; I think you should change your condition in WHERE

ScheduleEndDate < '2015/05/31'

To this, in order to get all dates which hasn't passed yet

ScheduleEndDate >= '2015/05/31'

Your query should look like

SELECT * FROM tblServiceUsersSchedule 
WHERE ScheduleEndDate IS NOT NULL
AND ScheduleEndDate >= '2015/05/31'
