title: SQL Import skip duplicates
body: <p>I am trying to do a bulk upload into a SQL server DB. The source file has duplicates which I want to remove, so I was hoping that the operation would automatically upload the first one, then discard the rest. (I've set a unique key constraint). Problem is, the moment a duplicate upload is attempted the whole thing fails and gets rolled back. Is there any way I can just tell SQL to keep going?</p>
