odps-inst: Describe the details of an instance.
$ desc instance ${instance_id};
try on your machine
The command "desc instance ${instance_id};" is a database command used to describe or provide information about a specific instance in a database.
Here's a breakdown of the command:
- "desc" is a short form of "describe," indicating that we want to retrieve information or details about an object in a database.
- "instance" refers to the type or category of the object we want to describe. In this case, it's likely an instance of a specific entity or table in the database.
- "${instance_id}" is a placeholder that represents the unique identifier or key of the instance we want to describe. The actual instance ID of the desired object should replace this placeholder before executing the command.
When executed, this command would retrieve and display relevant information about the specified instance, which could include attributes, data types, constraints, indexes, etc. The specific details provided usually depend on the database system being used.
