EDBBulkImportIdentityBehavior

This enum defines the behavior of the identity property/column when an entity is bulk-imported into a target table. It applies only to EnterpriseDB.

Enum Values

Name	Description
KeepIdentity	The value of the identity property/column will be kept and used. (This is the default value)
ReturnIdentity	The newly generated identity value from the target table will be set back to the entity.

Usability

This enum is used by both the BulkInsert and BulkMerge operations of RepoDb.EnterpriseDb.BulkOperations. Pass the value to the identityBehavior argument when calling the operation.

For BulkInsert:

using (var connection = new EDBConnection(connectionString))
{
    var people = GetPeople(1000);
    var insertedRows = connection.BulkInsert(people,
        identityBehavior: EDBBulkImportIdentityBehavior.ReturnIdentity);
}

For BulkMerge:

using (var connection = new EDBConnection(connectionString))
{
    var people = GetPeople(1000);
    var mergedRows = connection.BulkMerge(people,
        identityBehavior: EDBBulkImportIdentityBehavior.ReturnIdentity);
}

The DbDataReader overloads of BulkInsert and BulkMerge have no identityBehavior argument — a forward-only, single-pass reader cannot be rewound to correlate generated identity values back onto a source row.
