SqlBulkCopy Error handling / continue on error

Question

I am trying to insert huge amount of data into SQL server. My destination table has an unique index called \"Hash\".

I would like to replace my SqlDataAdapter impl

Answer 1

Slightly different approach than already suggested; Perform the SqlBulkCopy and catch the SqlException thrown:

    Violation of PRIMARY KEY constraint 'PK_MyPK'. Cannot insert duplicate 
key in object 'dbo.MyTable'. **The duplicate key value is (17)**.

You can then remove all items from your source from ID 17, the first record that was duplicated. I'm making assumptions here that apply to my circumstances and possibly not yours; i.e. that the duplication is caused by the exact same data from a previously failed SqlBulkCopy due to SQL/Network errors during the upload.
