  • Exception handling can handle multiple WHEN arms
  • Exception can re-raise with RAISE keyword
  • Snowflake can now also parse BEGIN ... EXCEPTION ... END

Example:

BEGIN
    SELECT 1;
EXCEPTION
    WHEN EXCEPTION_1 THEN
        SELECT 1;
    WHEN EXCEPTION_2 OR EXCEPTION_3 THEN
        SELECT 2;
        SELECT 3;
    WHEN OTHER THEN
        SELECT 4;
RAISE;
END;

- Exception handling can handle multiple `WHEN` arms
- Exception can re-raise with `RAISE` keyword
- Snowflake can now also parse `BEGIN ... EXCEPTION ... END`

Example:

```sql
BEGIN
    SELECT 1;
EXCEPTION
    WHEN EXCEPTION_1 THEN
        SELECT 1;
    WHEN EXCEPTION_2 OR EXCEPTION_3 THEN
        SELECT 2;
        SELECT 3;
    WHEN OTHER THEN
        SELECT 4;
RAISE;
END;
```
