Example Response

The following is an example of a successful response in synchronous mode:
```
{
 "is_success": true,
 "message": "",
 "job_mode": "sync"
}
```
The following is an example of a successful response in asynchronous mode:
```
{
 "is_success": true,
 "message": "",
 "job_id": "208b08d4-0dc2-4dd7-8879-ddd4c020d7aa",
 "job_type": "DDL",
 "job_mode": "async"
}
```
- If the database is deleted asynchronously, you can view the current job status by calling the API for querying job status. For details, see Querying Job Status.
- If cascade is set to true, all tables in the database will be deleted. Exercise caution when performing this operation.

Status Codes

Table 4 describes the status code.

**Table 4** Status codes
Status Code	Description
200	Deletion succeeded.
