title: Typeorm. use only the date part while querying via date and exclude the timestamp part
body: <p>I have a use case where I have to retrieve a users record from the database via his date of birth.
  The thing is that we have stored the date of birth of the user as datetime object which makes it very difficult to retrieve the users data, as we can not provide the exact date with timestamp.</p>
  <p>I tried looking for a functions support in typeorm using which I can just compare the provided date with only the date part of the birth date in database but did not find any reference anywhere.</p>
