# Information Schema FEEDBACK Table

The [Information Schema](/docs/server/reference/system-tables/information-schema.md) `FEEDBACK` table is created when the [Feedback Plugin](/docs/server/reference/plugins/other-plugins/feedback-plugin.md) is enabled, and contains the complete contents submitted by the plugin.

It contains two columns:

| Column          | Description                                          |
| --------------- | ---------------------------------------------------- |
| VARIABLE\_NAME  | Name of the item of information being collected.     |
| VARIABLE\_VALUE | Contents of the item of information being collected. |

It is possible to disable automatic collection, by setting the [feedback\_url](/docs/server/reference/plugins/other-plugins/feedback-plugin.md#feedback_url) variable to an empty string, and to submit the contents manually, as follows:

```sql
$ mysql -e 'SELECT * FROM information_schema.FEEDBACK' > report.txt
```

Then you can send it by opening [post](https://mariadb.org/feedback_plugin/post) in your browser, and uploading your generated `report.txt`. Or you can do it from the command line with (for example):

```sql
$ curl -F data=@report.txt https://mariadb.org/feedback_plugin/post
```

Manual uploading allows you to be absolutely sure that we receive only the data shown in the `information_schema.FEEDBACK` table and that no private or sensitive information is being sent.

## Example

```sql
SELECT * FROM information_schema.FEEDBACK\G
