將UNION ALL與我的日內表結合起來

Question

我見過幾個例子，但我不知道如何將我的查詢格式化爲一個聯合會，這個聯合會包含我的日內表。 TABLE_SUFFIX正在抓住我所有的日常餐桌，但我還需要抓住日內的smarttruck-6d137.com_usiinc_android_ANDROID.app_events_intraday_*。有人可以幫我使用UNION ALL格式嗎？謝謝。

SELECT 
    event_dim.date AS Date, 
    (
    SELECT 
    value.value.string_value 
    FROM 
    UNNEST(user_dim.user_properties) 
    WHERE 
    key = 'imei_id') AS IMEI, 
    (
    SELECT 
    value.value.string_value 
    FROM 
    UNNEST(user_dim.user_properties) 
    WHERE 
    key = 'division_id') AS Branch, 
    (
    SELECT 
    value.value.string_value 
    FROM 
    UNNEST(user_dim.user_properties) 
    WHERE 
    key = 'truck_id') AS Truck, 
    (
    SELECT 
    value.value.string_value 
    FROM 
    UNNEST(user_dim.user_properties) 
    WHERE 
    key = 'installer_id') AS Installer, 
    COUNT(*) AS Count 
FROM 
    `smarttruck-6d137.com_usiinc_android_ANDROID.app_events_*` 
CROSS JOIN 
    UNNEST(event_dim) AS event_dim 
WHERE 
    event_dim.name = 'app_exception' 
    AND EXISTS (
    SELECT 
    1 
    FROM 
    UNNEST(event_dim.params) 
    WHERE 
    key = 'fatal' 
    AND value.int_value = 1) 
    AND _TABLE_SUFFIX = Date 
GROUP BY 
    Date, 
    IMEI, 
    Branch, 
    Truck, 
    Installer 
ORDER BY 
    Date DESC, 
    Count DESC;

檢查，如果這對你的作品：

SELECT 
    event_dim.date AS Date, 
    (
    SELECT 
    value.value.string_value 
    FROM 
    UNNEST(user_dim.user_properties) 
    WHERE 
    key = 'imei_id') AS IMEI, 
    (
    SELECT 
    value.value.string_value 
    FROM 
    UNNEST(user_dim.user_properties) 
    WHERE 
    key = 'division_id') AS Branch, 
    (
    SELECT 
    value.value.string_value 
    FROM 
    UNNEST(user_dim.user_properties) 
    WHERE 
    key = 'truck_id') AS Truck, 
    (
    SELECT 
    value.value.string_value 
    FROM 
    UNNEST(user_dim.user_properties) 
    WHERE 
    key = 'installer_id') AS Installer, 
    COUNT(*) AS Count 
FROM 
    `smarttruck-6d137.com_usiinc_android_ANDROID.app_events_*` 
CROSS JOIN 
    UNNEST(event_dim) AS event_dim 
WHERE 
    event_dim.name = 'app_exception' 
    AND EXISTS (
    SELECT 
    1 
    FROM 
    UNNEST(event_dim.params) 
    WHERE 
    key = 'fatal' 
    AND value.int_value = 1) 
    AND REGEXP_EXTRACT(_TABLE_SUFFIX, r'(\d+)') BETWEEN '20170807' and '20170809' 
GROUP BY 
    Date, 
    IMEI, 
    Branch, 
    Truck, 
    Installer 
ORDER BY 
    Date DESC, 
    Count DESC; 

你可以改變我在選擇使用什麼方式最適合你的日子。

如果您將在Data Studio中使用該查詢，那麼我傾向於根據今天的日期創建日期範圍，並根據時間返回多少天。例如：

AND REGEXP_EXTRACT(_TABLE_SUFFIX, r'(\d+)') BETWEEN FORMAT_DATE("%Y%m%d", DATE_SUB(CURRENT_DATE(), INTERVAL 30 DAY)) and FORMAT_DATE("%Y%m%d", DATE_SUB(CURRENT_DATE(), INTERVAL 0 DAY)) 

這會自動在過去30天內從今天開始計數。您可以根據您的數據工作室報告中最適合的查詢來調整此查詢。

我想我自己想通了。通過刪除where子句中的_TABLE_SUFFIX = Date，BQ也使用通配符來獲取我的日內表。我不會假裝我完全理解這是爲什麼會起作用，但它確實如此。如果你能解釋的話，請加入。
