something like this:


insert db_client..destination_table(col1, col2, ...)
select
col1,
col2,
...
from db_master..source_table as srce
where not exists (select * from dest_table where KeyCol = srce.Keycol)

If there are no duplicates in source_table itself then there are no duplicates in destination_table with the given query.
Old data in source_table is not included in the given insert if the data already exists in destination_table.
