The MaxCompute console provides a query editor for you to execute SQL statements and analyze data. This topic describes how to use the query editor.
- Edit and execute SQL statements and authorization commands, such as access control list (ACL)-based authorization commands.
- Enable the MaxCompute Query Acceleration (MCQA) feature. After this feature is enabled, the time that is used to run small- and medium-sized query jobs is reduced from minutes to seconds. For more information about MCQA, see MCQA overview.
- Use and test MaxCompute based on its public datasets. By default, the public datasets are open to users.
- Analyze, download, and share query results by using Web Excel online.
- If you use and test MaxCompute for the first time, you can use the query editor to experience the core features of MaxCompute based on the public datasets.
- If you are a data analyst, you can use the query editor to query data. Then, you can switch to the analysis mode to analyze the query results by using Web Excel online. To reduce the frequency at which data is transferred and ensure data security, you can also download the query results to your computer for analysis.
- If you are a security administrator, you can find a required project and click Project permission management in the Actions column to manage role permissions. However, this feature is in trial use. In many scenarios, you must run commands to manage permissions. The query editor allows you to run most of the security commands without the need to perform additional configurations.
Open the query editor
- Log on to the MaxCompute console, select a region in the top navigation bar, and then click Query editing to open the query editor.
- In the Select Datasource dialog box, select MaxCompute for Type and select an existing project from the Workspace drop-down list.
Note If you select a project that is associated with a workspace in standard mode and submit a job by using the query editor, the job is submitted in a development project. The name of such a project is ended with _dev.
- Click OK. The SQL Query page appears.
