Access .adp :How to INSERT all but KEY violations

I am trying to append records from one table to another in a db running on
MSDE, knowing fullwell that some of the data in the source will be
duplicates of that in the destination table's pk.
What I would like to happen is to have the stored procedure plunk in all
records that don't violate the constraint
and silently let the duplicate info fall by the wayside. The trouble is SQL
server seems to abort the whole procedure if
even a single record violates the constraint.

In a regular Access mdb, an INSERT statement (append query) would do just
that. Of course it warns you of the violation but a DoCmd.SetWarnings FALSE
takes care of that.

Any ideas as to what I need to do to achieve that same thing?For example:

INSERT INTO TargetTable (key_col, col1, col2, ...)
SELECT S.key_col, S.col1, S.col2, ...
FROM SourceTable AS S
LEFT JOIN TargetTable AS T
ON S.key_col = T.key_col
WHERE T.key_col IS NULL

(where key_col is the primary key).
