writeExpressions method

Future<int> writeExpressions(
  1. Map<String, Expression<Object>> expressions
)

This is useful in combination with from and join to set columns based on other tables. For all other use cases see write.

Implementation

Future<int> writeExpressions(Map<String, Expression> expressions) async {
  updatedColumns
    ..clear()
    ..addAll(expressions);

  if (updatedColumns.isEmpty) {
    return Future.value(0);
  }

  final result = await _run();
  return result.affectedRows!;
}
