Google bigquery bigquery中的函数TIMESTAMP_SUB没有匹配签名

我试图在Google BigQuery中运行此查询，但是

No matching signature for function TIMESTAMP_SUB for argument types: DATETIME, INT64, DATE_TIME_PART. Supported signature: TIMESTAMP_SUB(TIMESTAMP, INTERVAL INT64 DATE_TIME_PART) at [8:5]

以下是查询：

#standardSQL
CREATE TEMPORARY FUNCTION URL_DECODE(enc STRING)
RETURNS STRING
LANGUAGE js AS """
  try { 
    return decodeURI(enc);;
  } catch (e) { return null }
  return null;
""";

select 
replace(JSON_EXTRACT(URL_DECODE(l.ed), '$.phone'),"\"","") as phone
from pixel_logs.full_logs l
where ev = 'user_authentication'
and ed not like '%filipe.ferminiano%'
AND TIMESTAMP_SUB(CURRENT_DATETIME(), interval 60 minute) > timestamp
group by
phone
;

CURRENT\u DATETIME（）

返回一个

DATETIME

值，而不是

时间戳

。也许你想使用

当前时间戳（）

CURRENT\u DATETIME（）

返回一个

DATETIME

值，而不是

时间戳

。也许你想使用

当前时间戳（）
