google-bigquery - Bigquery 与 where 一起使用

Question

bigquery 中以下查询的正确语法是什么？SELECT COUNT(children.names) WITHIN AS numberOfChildren FROM [dataset.tableId] where numberOfChildren > 10;

Answer 1

尝试添加一个子选择并将过滤器应用于外部选择：

SELECT numberOfChildren FROM (
   SELECT COUNT(children.names) WITHIN RECORD AS numberOfChildren 
   FROM [dataset.tableId]
) 
WHERE numberOfChildren > 10;
