OracleBulkImportPseudoTableType

This enum defines the type of staging (pseudo) table created during bulk-import operations. It applies only to Oracle.

It is used by the following bulk operations.

Enum Values

Name	Description
Auto	Chooses between `Physical` and `Memory` based on row count (`Physical` at 5,000 rows or more). This is the default.
Memory	A Global Temporary Table, private to each session. Safe for concurrent/multi-connection workloads.
Physical	An ordinary heap table, shared by every session. Only safe for sequential (non-concurrent) workloads against the same target table.

Every value currently resolves to Physical at runtime. ODP.NET’s direct-path load — used internally by every bulk operation — cannot write into a Global Temporary Table, failing with ORA-39826. This is a temporary driver-level limitation; Auto and Memory are kept in the enum so existing code doesn’t need to change once a working strategy is implemented. See Bulk Operations (Oracle) for details.

Usability

Pass the value to the pseudoTableType argument of the target operation.

using (var connection = new OracleConnection(connectionString))
{
    var people = GetPeople(1000);
    var insertedRows = connection.BulkInsert(people,
        pseudoTableType: OracleBulkImportPseudoTableType.Physical);
}
