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.
