By default, moving data between protected and unprotected tables is restricted. Source and target tables are required to have identical constraints to perform a bulk load to or from a table with row level security restrictions. This restriction guarantees all constraint column values are valid before moving them. If an invalid value is encountered, the bulk load terminates.
The system can be configured to allow client loader applications and SQL statements to move data between protected and unprotected tables.
