beginTransactionHandle method

TransactionHandle? beginTransactionHandle(int connectionId, int isolationLevel, { int savepointDialect = 0, int accessMode = 0, int lockTimeoutMs = 0, })

Begins a new transaction and returns a TransactionHandle wrapper.

See beginTransaction for the parameter contract. Returns a TransactionHandle on success, null on failure.

Implementation

TransactionHandle? beginTransactionHandle(
  int connectionId,
  int isolationLevel, {
  int savepointDialect = 0,
  int accessMode = 0,
  int lockTimeoutMs = 0,
}) {
  final txnId = beginTransaction(
    connectionId,
    isolationLevel,
    savepointDialect: savepointDialect,
    accessMode: accessMode,
    lockTimeoutMs: lockTimeoutMs,
  );
  if (txnId == 0) return null;
  return TransactionHandle(_connection, txnId);
}
