[GitHub] [arrow-datafusion] alamb opened a new issue, #2857: Implement `information_table.views`
alamb opened a new issue, #2857:
URL: https://github.com/apache/arrow-datafusion/issues/2857
**Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
https://github.com/apache/arrow-datafusion/pull/2830 added the sql to define a view into `information_schema.tables`
While this is useful, it isn't the standard location for such information -- the standard location is `information_schema.views`
For example, in mysql:
```sql
mysql> select table_catalog, table_schema, table_name, view_definition from information_schema.views where table_name = 'ff';
+---------------+--------------+------------+------------------------------------------------+
| TABLE_CATALOG | TABLE_SCHEMA | TABLE_NAME | VIEW_DEFINITION |
+---------------+--------------+------------+------------------------------------------------+
| def | foo | ff | select count(0) AS `count(*)` from `foo`.`foo` |
+---------------+--------------+------------+------------------------------------------------+
1 row in set (0.00 sec)
```
**Describe the solution you'd like**
1. Add `information_schema.views` (following the model of `information_schema.tables`, e.g. https://github.com/apache/arrow-datafusion/blob/master/datafusion/core/src/catalog/information_schema.rs#L136-L142)
2. Remove the non standard column `definition` from `information_schema.tables`
3. Update `SHOW CREATE TABLE` to use `information_schema.views`
**Describe alternatives you've considered**
N/A
**Additional context**
Kudos to @mrob95 for the initial implementation.

I think this is a good first issue because there is a model to follow (`information_schema.tables`) so this would be a good way to learn the existing code and tests
