  • I don't believe there is a way around this issue when using SQLBulkCopy

    In any event, these type of operations are generally time consuming so you may want to consider selecting only those rows where the primary key is not in the destination table when building your datareader.

  • I would suggest you to use SSIS to load data from source into destination.

  • sorry  sir .

                    but  with  SSIS   same problem . it rollback all  the data  if any duplication  occur  during bulk insert.

    i think  bulk copy not support duplication check.

  • With SSIS you can check which rows already exist, and skip them.
