docs: Query the given URL, returning a {@link Cursor} over the result set.
  
  @param distinct true if you want each row to be unique, false otherwise.
  @param table The table name to compile the query against.
  @param columns A list of which columns to return. Passing null will
  return all columns, which is discouraged to prevent reading
  data from storage that isn't going to be used.
  @param selection A filter declaring which rows to return, formatted as an
  SQL WHERE clause (excluding the WHERE itself). Passing null
  will return all rows for the given table.
  @param selectionArgs You may include ?s in selection, which will be
  replaced by the values from selectionArgs, in order that they
  appear in the selection. The values will be bound as Strings.
  @param groupBy A filter declaring how to group rows, formatted as an SQL
  GROUP BY clause (excluding the GROUP BY itself). Passing null
  will cause the rows to not be grouped.
  @param having A filter declare which row groups to include in the cursor,
  if row grouping is being used, formatted as an SQL HAVING
  clause (excluding the HAVING itself). Passing null will cause
  all row groups to be included, and is required when row
  grouping is not being used.
  @param orderBy How to order the rows, formatted as an SQL ORDER BY clause
  (excluding the ORDER BY itself). Passing null will use the
  default sort order, which may be unordered.
  @param limit Limits the number of rows returned by the query,
  formatted as LIMIT clause. Passing null denotes no LIMIT clause.
  @return A {@link Cursor} object, which is positioned before the first entry. Note that
  {@link Cursor}s are not synchronized, see the documentation for more details.
