Sql 如何使用配置单元提取阵列中的每个组件

我在蜂箱中有如下数据集。如何在不使用提取每行结果的横向视图分解（答案）的情况下拉出“答案”列中的每个组件？我希望结果是一致的。我使用配置单元SQL

dataset:
    id   | Answer
    -----| ----------
    123  | ["A","B","C","D","E"]
    456  | ["A","B","C","E"]
    789  | ["A","B","C"]


Expected outcome: 
    id   | Answer
    -----| ----------
    123  | "A","B","C","D","E"
    456  | "A","B","C","E"
    789  | "A","B","C"
