Question

希望能够将视图从一个项目移动（复制和替换）到另一个项目。

假设我们有Dev GCP项目1，以及集成和生产GCP项目。我希望能够将单个视图或特定数据集（不是表格）从Dev移动到Int，然后移动到Int到Prod。

我知道我可以使用以下Google Cloud Shell命令移动表格。

bq cp ProjectNumberDev.DatasetDev.TableDev ProjectNumberInt.DatasetInt.TableInt

但是，此命令仅适用于表而不是视图，有没有办法用视图执行此操作？或者是Table Insert / Post API脚本的唯一方法？

Per documentation:

Currently, there is no supported method for copying a view from one dataset to another. You must recreate the view in the target dataset.

You can copy the SQL query from the old view:

Issue the bq show command.
The "${default[3]}" flag can be used to control the output. If you are getting information about a view in a project other than your default project, add the project ID to the dataset in the following format: --format. To write the view properties to a file, add > [PROJECT_ID]:[DATASET] to the command.

[PATH_TO_FILE]

Meantime, if you can script all your views during the development then you can use CREATE VIEW statement in all environments

You can apply same approach for tables creation, etc.
