Bigquery-从整数列表中声明数组

我正试图将一个整数列表声明为名为 list_of_ints 。我的代码可以工作,但这似乎是一种变通方法:

DECLARE list_of_ints ARRAY <INT64>;
set list_of_ints = (
  SELECT ARRAY_AGG( DISTINCT some_ints)
  FROM (SELECT * FROM UNNEST ([11,22,33]) as some_ints) 
);

我希望

DECLARE list_of_ints ARRAY <INT64>;
set list_of_ints = ARRAY([11,22,33]);

但这似乎是不恰当的语法。是否有类似于上述尝试的方法在bigquery中将数组声明为变量?
