场不是叶场

Question

以下查询我收到错误"字段signupdate不是叶字段"

SELECT COUNT(*) AS cnt
FROM [adknowledge_data.ADKBatch_Combined_c]
WHERE ABS(HASH(MD5email) % 3 ) = 0
GROUP EACH BY MD5email, signupdate
HAVING cnt > 1

对于以下表模式:

MD5email:string

IP:字符串

signupdate:时间戳

Answer 1

这不是一个很好的错误消息,但至少有一个简单的解决方案来解决潜在的问题:在SELECT表达式中包含'signupdate'.

看到:

SELECT COUNT(*) c
FROM [fh-bigquery:bigdataspain.aggr_transactions_to] 
GROUP BY time

Error: Field time [...] is not a leaf field.

VS:

SELECT COUNT(*) c, time
FROM [fh-bigquery:bigdataspain.aggr_transactions_to] 
GROUP BY time

(works!)
