create static method

InsertFromValues? create(GeneratedTable<Object, GeneratedTable<Object, dynamic>> table, Insertable row)

Creates an InsertFromValues capturing columns of inserting the pending row into the given table.

Implementation

static InsertFromValues? create(GeneratedTable table, Insertable row) {
  final rawValues = row.toColumns(true);

  // apply default values for columns that have one
  LinkedHashMap<String, Expression> map = LinkedHashMap();
  for (final column in table.columns) {
    final columnName = column.name;

    if (rawValues.containsKey(columnName)) {
      final value = rawValues[columnName]!;
      map[columnName] = value;
    } else {
      if (column.clientDefault case final clientDefault?) {
        map[columnName] = Variable(clientDefault(), column.sqlType);
      }
    }

    // column not set, and doesn't have a client default. So just don't
    // include this column
  }

  // The rowid is not included in the list of columns since it doesn't show
  // up in selects, but we should also add that value to the map for inserts.
  if (rawValues.containsKey('rowid')) {
    map['rowid'] = rawValues['rowid']!;
  }

  if (map.isNotEmpty) {
    return InsertFromValues._(map);
  }
  return null;
