But, unfortunately the table already contains a few records with matching keys. What to do? So what to do. Googled till I was sweaty. Finally, the most useful advice is the one documented in SQLMag.com: Umachandar Jayachandran - A Bulk-Copy Procedure http://www.sqlmag.com/article/sql-server/a-bulk-copy-procedure The solution is actually attributed to Alejandro Mesa, a database programmer for Simplex Medical in Fort Myers, Florida Marcos Kirchner, a student at the University of Blumenau (FURB) in Santa Catarina, Brazil The advice is to create a unique index on the columns that infer sameness and be sure to indicate that duplicates should simply be discarded. SQL The following statement creates the new index: Syntax CREATE UNIQUE INDEX [index-name] ON [table-name] ( [column-1] , [column-2] , [column-3] ) WITH ignore_dup_key Sample CREATE UNIQUE INDEX [uq_idx_companies_id] ON Companies(CompanyId) WITH ignore_dup_key Interpretation So it looks like it is OK to leave everything as is, just create a unique index (with ignore_no_dup) that has the same columns as the primary key. Import the data and go back and drop the ignore_dup_key index. Like this:Like Loading...
