streamStartAsync method

int? streamStartAsync(
  1. int connectionId,
  2. String sql, {
  3. int fetchSize = 1000,
  4. int chunkSize = 64 * 1024,
})

Starts async batched streaming query execution.

Returns stream ID (>0) on success, 0 on native failure, and null when async stream API is unavailable.

Implementation

int? streamStartAsync(
  int connectionId,
  String sql, {
  int fetchSize = 1000,
  int chunkSize = 64 * 1024,
}) {
  if (!_bindings.supportsAsyncStreamApi) {
    return null;
  }
  return _withSql<int>(
    sql,
    (sqlPtr) => _bindings.odbc_stream_start_async(
      connectionId,
      sqlPtr,
      fetchSize,
      chunkSize,
    ),
  );
}
