### Custom SQL Template
|
||
|
|
|
||
|
|
Clickhouse 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
|
||
|
|
ALTER TABLE `{schema}`.{table} MODIFY COLUMN {column} COMMENT {description};
|
||
|
|
```
|
||
|
|
|
||
|
|
The list of variables for custom SQL can be found [here](/connectors/ingestion/workflows/reverse-metadata#custom-sql-template).
