Script Development Process

The script development function provides the following capabilities:

Provides an online script editor for developing and debugging SQL, Python, and Shell scripts.
Supports script import and export.
Allows use of variables and functions.
Provides editing locks for collaborative development.
Supports script version management and generation of saved and submitted versions.

If you save a script multiple times within a minute, only one version is recorded. If the intermediate data is important, you can click Save new version to save and add a version.
Allows you to copy long script names. Click , perform fuzzy search to query matched scripts, and click the copy button next to a long script name to copy it.
Allows you to right-click a script to quickly copy the script name and to quickly close an opened script tab page.
Provides a link in the execution results of MRS Spark SQL and MRS Hive SQL scripts that use a connection of the MRS API type. Through this link, you can switch to MRS Yarn to view execution logs.
Allows you to switch to the task release page by placing the cursor on and clicking Release when developing a script in enterprise mode.
Allows you to filter submitted and unsubmitted scripts. Unsubmitted scripts are marked in red.
Displays script parameters in a dialog box. Parameter values can be changed, but parameter names cannot. You can click Test Parameters to view (but not modify) the parameters referenced by the script and the environment variables configured in the environment. Parameters in the SQL statement can be sorted by name.
Supports configuration of the SQL editor style. Move the cursor to and click Style Configuration to configure the editor, icon display, annotation templates, and shortcut keys that can be used in the SQL script editor.
Allows you to view SQL query results in a table or list. You can click Style Configuration and set SQL Query Result Display Mode on the Configure Editor tab page.
Allows you to go to the release page from the script development page in enterprise mode. Place the cursor over and click Release to go to the task release page.
Allows you to view tables of Hive SQL, DLI SQL, RDS SQL, and DWS SQL scripts. You can expand a table name to view the column names, field types, and descriptions in the table.
