This method removes the specified OracleBulkCopyColumnMapping element from the OracleBulkCopyColumnMappingCollection.

Declaration

// C#
public void Remove(OracleBulkCopyColumnMapping value);

Parameters

• value

  The OracleBulkCopyColumnMapping object to be removed from the collection.

Exceptions

InvalidOperationException - The bulk copy operation is in progress.

Remarks

The Remove method is most commonly used when a single OracleBulkCopy instance processes more than one bulk copy operation. If column mappings are created for one bulk copy operation, mappings that no longer apply must be removed after the WriteToServer method invocation and before mappings are defined for the next bulk copy. The Clear method can clear the entire collection, and the Remove and the RemoveAt methods can remove mappings individually.

It is usually more efficient to perform several bulk copies using the same OracleBulkCopy instance than to use a separate OracleBulkCopy for each operation.
