The names of files that were updated in the `pull_requests` table of the
DevLake database can be found in the `pull_request_commits` table. This table
shows the commits associated with pull requests, which include the files that
were changed.
Here is the relevant schema information:
```md
#### pull_request_commits
This table shows the commits associated with pull requests. Each entry
represents a commit that is part of a pull request.
| **field** | **type** | **length** | **description** | **key**
|
|:----------------|:---------|:-----------|:----------------|:---------------|
| `pull_request_id` | varchar | 255 | Pull Request ID |
FK_pull_requests.id |
| `commit_id` | varchar | 255 | Commit ID | FK_commits.id
|
```
To locate the names of files that were updated, you would need to join the
`pull_requests` table with the `pull_request_commits` table and then with the
`commits` table, which contains the details of the files changed in each commit.
Additionally, the `pull_request_files` table provides detailed information
about the files changed in pull requests:
```md
#### pull_request_files
This table shows the files changed in pull requests. Multiple entries can
exist per pull request.
| **field** | **type** | **length** | **description**
| **key** |
|:---------------|:---------|:-----------|:-------------------------------------------|:---------------|
| `pull_request_id` | varchar | 255 | Pull Request ID
| FK_pull_requests.id |
| `file_path` | varchar | 255 | The path of the file that was
changed | |
| `change_type` | varchar | 50 | The type of change (e.g., added,
modified, deleted) | |
| `additions` | int | | The number of lines added
| |
| `deletions` | int | | The number of lines deleted
| |
```
By leveraging these tables, you can effectively track the files that were
updated in the pull requests
