How can I cast a value to SMALLINT in Databricks SQL?
You can cast a value to SMALLINT in Databricks SQL by using the `smallint(expr)` function. This function casts the value of `expr` to SMALLINT. Here's an example:
```sql
SELECT smallint(1234.56) AS smallint_value;
```
This will cast the value `1234.56` to a SMALLINT, resulting in `1234`.
