如何使用 UNION ALL 函数在 SQL 中创建新表？

Question

我正在研究我的谷歌分析课程案例研究，我正在尝试通过组合 12 个数据集在 Big Query-SQL 上创建一个新表。我不断收到此错误：

语法错误：[1:14] 处出现意外的字符串文字“bikeshare_total”

请参阅以下查询。我尝试了不同的变体，但遇到了相同的错误。

CREATE TABLE "bikeshare_total" AS (
SELECT *
FROM `cyclisticjan21-dec21.Bike_share.Jan2021`
UNION ALL
SELECT * 
FROM `cyclisticjan21-dec21.Bike_share.Feb2021`
UNION ALL
SELECT *
FROM `cyclisticjan21-dec21.Bike_share.March2021`
UNION ALL
SELECT *
FROM `cyclisticjan21-dec21.Bike_share.April2021`
UNION ALL
SELECT * 
FROM `cyclisticjan21-dec21.Bike_share.May2021`
UNION ALL
SELECT *
FROM `cyclisticjan21-dec21.Bike_share.June2021`
UNION ALL
SELECT * 
FROM `cyclisticjan21-dec21.Bike_share.July2021`
UNION ALL
SELECT *
FROM `cyclisticjan21-dec21.Bike_share.August2021`
UNION ALL
SELECT * 
FROM `cyclisticjan21-dec21.Bike_share.Sep2021`
UNION ALL
SELECT *
FROM `cyclisticjan21-dec21.Bike_share.Oct2021`
UNION ALL
SELECT * 
FROM `cyclisticjan21-dec21.Bike_share.Nov2021`
UNION ALL
SELECT *
FROM `cyclisticjan21-dec21.Bike_share.Dec2021`)

Answer 1

您错过了项目名称吗？

或者尝试删除引号。

Answer 2

尝试使用反引号作为表名并删除括号：

CREATE TABLE `bikeshare_total` AS 
SELECT *
FROM `cyclisticjan21-dec21.Bike_share.Jan2021`
UNION ALL
SELECT * 
FROM `cyclisticjan21-dec21.Bike_share.Feb2021`
UNION ALL
SELECT *
FROM `cyclisticjan21-dec21.Bike_share.March2021`
UNION ALL
SELECT *
FROM `cyclisticjan21-dec21.Bike_share.April2021`
UNION ALL
SELECT * 
FROM `cyclisticjan21-dec21.Bike_share.May2021`
UNION ALL
SELECT *
FROM `cyclisticjan21-dec21.Bike_share.June2021`
UNION ALL
SELECT * 
FROM `cyclisticjan21-dec21.Bike_share.July2021`
UNION ALL
SELECT *
FROM `cyclisticjan21-dec21.Bike_share.August2021`
UNION ALL
SELECT * 
FROM `cyclisticjan21-dec21.Bike_share.Sep2021`
UNION ALL
SELECT *
FROM `cyclisticjan21-dec21.Bike_share.Oct2021`
UNION ALL
SELECT * 
FROM `cyclisticjan21-dec21.Bike_share.Nov2021`
UNION ALL
SELECT *
FROM `cyclisticjan21-dec21.Bike_share.Dec2021`
;
