You can specify this option for indexes created on load isolated tables.
WITH LOAD IDENTITY
Records the RowLoadID for the index created on a load isolated table.
- Does not record RowLoadID with the ROWIDs in a NUSI. The base row, using the qualified ROWID from the index row must be used to determine the committed property. This index may be simpler to maintain but read operations are more expensive than the regular NUSI based option, limiting the usability of index.
