Member Function Documentation

◆ Commit()

void ydb::Transaction::Commit ( OperationSettings settings = {} )

Commit the transaction. The options that are missing in settings are taken from the static config or driver defaults. settings can be overridden by dynamic config's options for Commit "query".

◆ Execute() [1/2]

template<typename... Args>

ExecuteResponse ydb::Transaction::Execute	(	const Query &	query,
		Args &&...	args )

Execute a single data query as a part of the transaction. Query parameters are passed in Args as "string key - value" pairs:

client.ExecuteDataQuery(query, "name1", value1, "name2", value2, ...);

Use ydb::PreparedArgsBuilder for storing a generic buffer of query params if needed.

◆ Execute() [2/2]

template<typename... Args>

ExecuteResponse ydb::Transaction::Execute	(	OperationSettings	settings,
		const Query &	query,
		Args &&...	args )

Definition at line 199 of file transaction.hpp.

◆ GetNativeTransaction()

NYdb::TTransactionBase & ydb::Transaction::GetNativeTransaction ( )

Get native transaction

Warning: Use with care! Facilities from <core/include/userver/drivers/subscribable_futures.hpp> can help with non-blocking wait operations.

◆ Rollback()

void ydb::Transaction::Rollback ( )

Rollback the transaction. The operation settings are taken from Begin settings.
