Question

我是SQL的新手...请不要介意我是否要求愚蠢的问题.. 这是我的第一个Query，它应该基于代码执行数据 WHERE hits.transaction.transactionId IS NOT NULL

我有多个SELECT，FROM和WHERE语句。我该如何纠正这个。

SELECT

date,fullvisitorid AS Users,
hits.product.v2ProductName AS Product_Name,
(hits.product.productPrice/1000000) AS Product_Price,
(hits.product.productQuantity) AS Product_Quantity,
(hits.product.productrevenue/1000000) AS Product_Revenue

FROM ([DATASET])

WHERE hits.transaction.transactionId IS NOT NULL

-------------------------------------------------------------------
SELECT
hits.eCommerceAction.action_type AS Product_Viewed

FROM ([DATASET])

WHERE hits.eCommerceAction.action_type = '2'

Answer 1

你可以把它结合起来像

SELECT
date,fullvisitorid AS Users,
hits.product.v2ProductName AS Product_Name,
(hits.product.productPrice/1000000) AS Product_Price,
(hits.product.productQuantity) AS Product_Quantity,
(hits.product.productrevenue/1000000) AS Product_Revenue,
hits.eCommerceAction.action_type AS Product_Viewed
from ([DATASET])
WHERE hits.transaction.transactionId IS NOT NULL 
AND
hits.eCommerceAction.action_type = '2'

Answer 2

如果要在WHERE子句中组合多个条件，请使用AND/OR个关键字。

SELECT

date,fullvisitorid AS Users,
hits.product.v2ProductName AS Product_Name,
(hits.product.productPrice/1000000) AS Product_Price,
(hits.product.productQuantity) AS Product_Quantity,
(hits.product.productrevenue/1000000) AS Product_Revenue,
hits.eCommerceAction.action_type AS Product_Viewed

FROM ([DATASET])

WHERE hits.transaction.transactionId IS NOT NULL
AND
hits.eCommerceAction.action_type = '2'

具有多个WHERE语句的子查询...
