问题描述
是否有可能在BigQuery中使用现有表对基于JOIN的表进行更新?
Is it possible to do an UPDATE on a table based on a JOIN with an existing table in BigQuery?
当我在以下数据库上尝试使用此语句时( https://bigquery.cloud. google.com/dataset/pfamdb:pfam31 ),
When I try this statement on the following database (https://bigquery.cloud.google.com/dataset/pfamdb:pfam31),
UPDATE pfam31.uniprot
SET uniprot.auto_architecture = uniprot_architecture.auto_architecture
INNER JOIN
pfam31.uniprot_architecture using(uniprot_acc)
我得到与INNER JOIN
有关的错误,而我们期望使用WHERE
.我应该怎么做(如果可能的话)?
I get errors relating to the INNER JOIN
, with WHERE
being expected instead. How should I be doing this (if it's possible)?
推荐答案
UPDATE `pfam31.uniprot` a
SET a.auto_architecture = b.auto_architecture
FROM `pfam31.uniprot_architecture` b
WHERE a.uniprot_acc = b.uniprot_acc
