google-analytics - 在自定义查询中查询数据时，格式化event_date和event_timestamp大查询

Question

您好以下是我的查询以获取大query中的一些数据想要知道我们如何格式化date和time stamp

SELECT
  *
FROM (
  SELECT
    (
    SELECT
      x.value
    FROM
      UNNEST(user_properties) x
    WHERE
      x.key='restaurantName'
      AND x.value IS NOT NULL).string_value AS restaurantName,
    event_date AS date,
    event_timestamp AS time,
    event_name AS Event,
    (
    SELECT
      x.value
    FROM
      UNNEST(user_properties) x
    WHERE
      x.key='restaurantId'
      AND x.value IS NOT NULL).string_value AS restaurantID,
    (
    SELECT
      x.value
    FROM
      UNNEST(user_properties) x
    WHERE
      x.key='user_id'
      AND x.value IS NOT NULL).string_value AS user
  FROM
    `analytics.events_*`
  WHERE
    event_name = "OrderSummary"
    AND app_info.id = "app_Id"
  ORDER BY
    event_timestamp ASC)
WHERE
  NOT(restaurantName IS NULL
    OR restaurantID="someName")

我正在正确过滤数据，但无法格式化

您期望在输出中使用的格式？日期= 28-11-2019和时间= 04:22:13


以下是BigQuery标准SQL

更改/修复仅在下面两行中

event_date AS date,
event_timestamp AS time,  

因此，而不是上面-在下面使用

FORMAT_DATE('%d-%m-%Y', PARSE_DATE('%Y%m%d', event_date)) AS date, 
FORMAT_TIME('%T', TIME(TIMESTAMP_MICROS(event_timestamp))) time,   

和各自的输出列将像

Row date        time     
1   28-11-2019  04:22:13     

注意：我假设event_date字段是STRING数据类型。如果它实际上是INT64，则只需要ue CAST(event_date AS STRING)而不是event_date
