There's no easy way to do a bulk insert using a CI! Component interface just isn't suited to do that. Your array idea wont help, I don't think.
The best way would be to write your own interface using a traditional tool like SQR or Application Engine. If you want to use bulk insert capabilities then try using file layouts and application engine.

Sorry Michael, but there isn't an easy way for this.

Hi Compshack.

Thanks for your prompt reply...Wat if we load the data from the CSV file to a staging table...then is there any easy way to do this...because my manager said that the data may be loaded into a staging table..if not he said that we may have to load it into a staging table..let me know about any easy method if data is there in a staging table..Thanks.

If data is already loaded on staging tables, then you can use application engine to load the data. It should be pretty easy to do with some SQL actions. Now, using component interface to insert data will put you back where you started, and that is inserting one row of data at a time. The benefit from using this method is that all of your business logic (edits) behind your component will fire on the data being inserted, thus almost no coding to edit data will be required.

If you want bulk inserts, you would then need to add your own business logic to the data being loaded from the staging table to your core tables. If data is not already on staging tables, you will have to load them in using file layouts to read data in from your CSV file.
