Hi Ravi,

Inserting more that one row at a time is the reason for SQL. SQL is known as a “SET” based language. Which means “more than one row at a time”. Programming languages are by nature “iterative”. Meaning one record at a time. So ultimately, inserting one row at a time is easy, depending on the source of the data. For you, I’m going to assume your best input method would be BCP. BCP allows multple rows contained in a file to be inserted in a set based method. Look into that and let me know if you have any questions.

Thanks,
Derek
