Grant Identity and Access Management IAM roles that give users the necessary permissions to perform each task in this document. To get information or metadata about a dataset, you need the bigquery. Each of the following predefined IAM roles includes the permissions that you need in order to get information or metadata about a dataset:.
The description and details appear in the details panel. The tables for a dataset are listed with the dataset name in the Explorer panel. By default, anonymous datasets are hidden from the Cloud Console. To show information about anonymous datasets, use the bq command-line tool or the API. Issue the bq show command. The --format flag can be used to control the output. To show information about an anonymous dataset , use the bq ls --all command to list all datasets and then use the name of the anonymous dataset in the bq show command.
Enter the following command to display information about mydataset in your default project. Enter the following command to display information about mydataset in myotherproject. Call the datasets. Before trying this sample, follow the Go setup instructions in the BigQuery quickstart using client libraries.
Before trying this sample, follow the Java setup instructions in the BigQuery quickstart using client libraries. Before trying this sample, follow the Node. For more information, see the BigQuery Node.
Before trying this sample, follow the Python setup instructions in the BigQuery quickstart using client libraries. The metadata returned is for all datasets in the default project — myproject. Go to the BigQuery page. Enter the following standard SQL query in the Query editor box. To control access to datasets in BigQuery, see Controlling access to datasets.
