I want to Import several delimited text files into SQL Server using DTS. If i am not using any Index on the table, my program work fine but if i use primary index, on the very first violation of the index DTS Rollbacks all the imported data and thus in effect importing no data at all.

How can i eliminate this?

I want to import million records at a time that may contain duplicate records too and i want to skip duplicate records while importing records in one go.

I don't want to use temporary tables in this process.

You can loop and import the records one by one.  Each time before you import your row, you can check if the primary key already exists, if it does then you can just loop to the next one, if not, import it.

Hi agarwalyogi,

You can combine your several delimited files into one single delimited file and then use SQL query in DTS wizard to eliminate duplicate records from your delimited file and then export to SQL server.

Cheers!

So what if the primary key is the same but there are differences in the rest of the records?

You can also set your "max error count" to be 9999 and it will consider it a "warning" and not abort....
