Methods
Consume(RelationalDataReader)
Consumes the data reader created by Execute(IRelationalConnection).
protected override void Consume(RelationalDataReader reader)Parameters
readerRelationalDataReaderThe data reader.
ConsumeAsync(RelationalDataReader, CancellationToken)
Consumes the data reader created by ExecuteAsync(IRelationalConnection, CancellationToken).
protected override Task ConsumeAsync(RelationalDataReader reader, CancellationToken cancellationToken = default)Parameters
readerRelationalDataReaderThe data reader.
cancellationTokenCancellationTokenA CancellationToken to observe while waiting for the task to complete.
Returns
- Task
A task that represents the asynchronous operation.
ConsumeResultSetWithPropagation(int, RelationalDataReader)
Consumes the data reader created by Execute(IRelationalConnection), propagating values back into the ModificationCommand.
protected virtual int ConsumeResultSetWithPropagation(int commandIndex, RelationalDataReader reader)Parameters
commandIndexintThe ordinal of the command being consumed.
readerRelationalDataReaderThe data reader.
Returns
- int
The ordinal of the next command that must be consumed.
ConsumeResultSetWithPropagationAsync(int, RelationalDataReader, CancellationToken)
Consumes the data reader created by ExecuteAsync(IRelationalConnection, CancellationToken), propagating values back into the ModificationCommand.
protected virtual Task<int> ConsumeResultSetWithPropagationAsync(int commandIndex, RelationalDataReader reader, CancellationToken cancellationToken)Parameters
commandIndexintThe ordinal of the command being consumed.
readerRelationalDataReaderThe data reader.

protected virtual Task<int> ConsumeResultSetWithoutPropagationAsync(int commandIndex, RelationalDataReader reader, CancellationToken cancellationToken)Parameters
commandIndexintThe ordinal of the command being consumed.
readerRelationalDataReaderThe data reader.
cancellationTokenCancellationTokenA CancellationToken to observe while waiting for the task to complete.
Returns
- Task<int>
A task that represents the asynchronous operation. The task contains the ordinal of the next command that must be consumed.
ThrowAggregateUpdateConcurrencyException(int, int, int)
Throws an exception indicating the command affected an unexpected number of rows.
