> Snowflake asset types that description reverse sync supports, and the statement Atlan runs in Snowflake for each one.

This reference lists the asset types that [description reverse sync](https://docs.atlan.com/llms/connectors/snowflake/push-description-updates-to-snowflake/llms.txt) supports, and the statement Atlan runs in Snowflake for each one.

## Supported asset types

| Atlan asset | Statement Atlan runs in Snowflake |
|---|---|
| Database | `COMMENT ON DATABASE "<db>" IS '...'` |
| Schema | `COMMENT ON SCHEMA "<db>"."<schema>" IS '...'` |
| Table, external table | `COMMENT ON TABLE "<db>"."<schema>"."<table>" IS '...'` |
| Dynamic table | `COMMENT ON DYNAMIC TABLE "<db>"."<schema>"."<table>" IS '...'` |
| Iceberg table | `ALTER ICEBERG TABLE "<db>"."<schema>"."<table>" SET COMMENT = '...'` |
| View | `COMMENT ON VIEW "<db>"."<schema>"."<view>" IS '...'` |
| Materialized view | `COMMENT ON MATERIALIZED VIEW "<db>"."<schema>"."<view>" IS '...'` |
| Function | `COMMENT ON FUNCTION "<db>"."<schema>"."<function>"(<argument types>) IS '...'` |
| Column of a table, external table, or dynamic table | `COMMENT ON COLUMN "<db>"."<schema>"."<table>"."<column>" IS '...'` |
| Column of an Iceberg table | `ALTER ICEBERG TABLE "<db>"."<schema>"."<table>" ALTER COLUMN "<column>" COMMENT '...'` |
| Column of a view or materialized view | `ALTER VIEW "<db>"."<schema>"."<view>" ALTER COLUMN "<column>" COMMENT '...'` |

Atlan doesn't push descriptions for any other asset type, for example procedures, stages, streams, and pipes.

## Statement behavior

- Each statement sets the comment to the description of the asset at the time Atlan applies the edit. If you edit a description several times in a short time, Snowflake gets the latest text.
- A comment on a view column or a materialized view column doesn't change the view definition or its grants. Atlan doesn't recreate the view.
- Each statement needs the `OWNERSHIP` privilege on the object. For details, see [Grant Snowflake privileges](https://docs.atlan.com/llms/connectors/snowflake/push-description-updates-to-snowflake/llms.txt).
- Atlan runs each statement with the query tag `atlan-snowflake-description-reverse-sync`.
