### Custom SQL Template

Redshift supports custom SQL templates for metadata changes. The template is interpreted using python f-strings.

Here are examples of custom SQL queries for metadata changes:

```sql
-- Update column description
COMMENT ON COLUMN {database}.{schema}.{table}.{column} IS {description};
```

The list of variables for custom SQL can be found [here](/connectors/ingestion/workflows/reverse-metadata#custom-sql-template).
