Google Analytics (分析) 4 使用者資料匯出作業的查詢

本頁中的查詢範例適用於 Google Analytics (分析) 4 的 BigQuery 使用者資料匯出功能。BigQuery 使用者資料匯出功能每天都會建立兩個資料表：

  1. users_YYYYMMDD 資料表，其中包含每個已變更使用者 ID 的資料列。
  2. pseudonymous_users_YYYYMMDD 資料表，每個變更的匿名 ID 自成一列。

詳情請參閱 BigQuery Export 使用者資料結構定義。

查詢特定日期範圍

如要從 BigQuery 使用者資料匯出資料集中查詢特定日期範圍，請在查詢的 WHERE 子句中使用 _TABLE_SUFFIX 虛擬資料欄。

舉例來說，下列查詢會計算在 2023 年 8 月 1 日至 2023 年 8 月 15 日之間更新的不重複使用者人數，且生命週期參與率至少為五分鐘。

使用者

-- Example: Query a specific date range for users meeting a lifetime engagement criterion.
--
-- Counts unique users that are in the BigQuery user-data exports for a specific date range and have
-- a lifetime engagement of 5 minutes or more.

SELECT
  COUNT(DISTINCT user_id) AS user_count
FROM
  -- Uses a table suffix wildcard to define the set of daily tables to query.
  `PROJECT_ID.analytics_PROPERTY_ID.users_202308*`
WHERE
  -- Filters to users updated between August 1 and August 15.
  _TABLE_SUFFIX BETWEEN '01' AND '15'
  -- Filters by users who have a lifetime engagement of 5 minutes or more.
  AND user_ltv.engagement_time_millis >= 5 * 60 * 1000;

pseudonymous_users

-- Example: Query a specific date range for users meeting a lifetime engagement criterion.
--
-- Counts unique pseudonymous users that are in the BigQuery user-data exports for a specific date
-- range and have a lifetime engagement of 5 minutes or more.

SELECT
  COUNT(DISTINCT pseudo_user_id) AS pseudo_user_count
FROM
  -- Uses a table suffix wildcard to define the set of daily tables to query.
  `PROJECT_ID.analytics_PROPERTY_ID.pseudonymous_users_202308*`
WHERE
  -- Filters to users updated between August 1 and August 15.
  _TABLE_SUFFIX BETWEEN '01' AND '15'
  -- Filters by users who have a lifetime engagement of 5 minutes or more.
  AND user_ltv.engagement_time_millis >= 5 * 60 * 1000;

每個示例都使用下列兩項功能，將資料限制為 2023 年 8 月 1 日至 2023 年 8 月 15 日：

  1. FROM 子句中的萬用字元 202308*。
  2. WHERE 子句中的 _TABLE_SUFFIX 條件，可根據資料表名稱的萬用字元部分篩選資料表。202308* 的萬用字元部分是日期，

您可以使用類似方法查詢多個月的資料。舉例來說，如要查詢 2023 年 1 月到 10 月的資料，請將查詢修改為：

  1. 萬用字元 2023*。
  2. _TABLE_SUFFIX BETWEEN '0101' AND '1031' 的 _TABLE_SUFFIX 條件。

也可以查詢數年的資料。舉例來說，如要查詢 2022 年 10 月到 2023 年 2 月的資料，請將查詢修改為：

  1. 萬用字元 202*。
  2. _TABLE_SUFFIX BETWEEN '21001' AND '30331' 的 _TABLE_SUFFIX 條件。

近期使用者屬性變更的使用者 ID

以下查詢說明如何擷取最近變更特定使用者屬性的所有使用者的 user_id 和 pseudo_user_id。
