Bulk insert, skip rows with duplicate key error?

Does sql server have a way to handle errors in a sproc which would allow
one to insert rows, ignoring rows which would create a duplicate key
violation? I know if one loops one can handle the error on a row by row
basis. But is there a way to skip the loop and do it as a bulk insert?
It's easy to do in Access, but I'm curious to know if SQL Server proper
can handle like this. I am guessing that a looping operation would be
slower to execute?

I'm a little uncertain what you are talking about. In SQL Server "bulk
insert" is a special operation where you load many rows direct from a
file. Or are you still talking about regular SQL statements?

In the latter case, use

INSERT tbl
SELECT ...
FROM src
WHERE NOT EXISTS (SELECT *
FROM tbl
WHERE tbl.keycol = src.keycol)

which should be the normal way to do it in Access - or any other SQL engine
for that matter - as well.

If you are specifically talking bulk load from file, then above is still
possible in SQL 2005 if you use OPENROWSET(BULK ) as the table source. If
you use BULK INSERT or BCP (the only options on SQL 2000), I believe it's
possible by using the IGNORE_DUP_KEY option on the index, but a more
common procedure is to load the file to staging table and move on from
there.

Thanks Erland. I meant a regular sql operation. I will take a look at
your suggestion, it looks good. Access has another way of handling this
(non-sql) and while the syntax you suggest probably works in Access,
I've never tried it.

Hi all, We have an application through which we are bulk inserting rows into a view. The definition of the view is such that it selects columns from a table on a remote server. I have added the servers using sp_addlinkedserver on both database servers.
