Comparing string dates in SQL

I have a SQL query which outputs dates as a Char field so I can have blank date fields as '' instead of 1900-01-01.

I am trying to write the query so only records with anExpiresDate > getdate() - 19:

ExpiresDate
  >convert(char,GETDATE()-19,101)

However, when the the query runs, I get data for prior years witin the Month and Day period, but for prior years.

What is the syntax to only get data > 7/1/2015 and not anything for July of 2014.

ExpiresDate is stored as Varchar (30).

Thanks

Why don't you convert the ExpiresDate?

CAST(ISNULL(ExpiresDate, '') AS datetime) > DATEADD(d, -19, GETDATE())

I'd recommend this: DATE and TIME ... don't be scared, and do it right (the first time)

It isn't good practice to store date/time information as strings, even more so if you have used MM/DD/YYYY as the storage format.
