Can a data-base check if a date already exist?

Every week our data base is charge with the new dates but last week,we were wrong and in the new query there were some old ones(then we had some dates twice in the db),so i wonder if i could put something in the design in order to check before if a date already exist.Thanks a lot .

Sincerely,

Beatriz

You’ll need to say more about what you’re doing. It’s possible to check whether a document with a given date value already exists. However, whether you get a chance to do that depends on how you’re putting new documents in.
