public sealed class TransactionSelector : IMessage<TransactionSelector>, IEquatable<TransactionSelector>, IDeepCloneable<TransactionSelector>, IBufferMessage, IMessage
Reference documentation and code samples for the Google Cloud Spanner v1 API class TransactionSelector.
This message is used to select the transaction in which a
[Read][google.spanner.v1.Spanner.Read] or
[ExecuteSql][google.spanner.v1.Spanner.ExecuteSql] call runs.
See [TransactionOptions][google.spanner.v1.TransactionOptions] for more
information about transactions.
Begin a new transaction and execute this read or SQL query in
it. The transaction ID of the new transaction is returned in
[ResultSetMetadata.transaction][google.spanner.v1.ResultSetMetadata.transaction],
which is a [Transaction][google.spanner.v1.Transaction].
