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.
