  Yes it can be done by setting IDENTITY_INSERT ON

  Please follow the below steps:

  1) SET IDENTITY_INSERT ON

  2) insert the values using a INSERT Sql.

  3) SET IDENTITY_INSERT OFF

  Do remember to turn off the identity_insert to OFF again.

  Keep in mind columns with the identity property are meant to generate their own value in a given sequence.

  (check books online for seed and increment)

  However - as replied by the others - , using set identity insert for a given table is an acceptable solution to support a load.

  After such load, dbcc checkident should be ran so the engine knows which value to generate next.

  Check books online DBCC CHECKIDENT for the options and usage info.
