question: Why does casting TIMESTAMP_NTZ to BIGINT fail in Spark, and how can I convert
it to a numeric value?

TIMESTAMP_NTZ cannot be cast directly to numeric types like BIGINT in Spark. To convert to a numeric representation (epoch seconds), use the to_unix_timestamp function.

```sql
SELECT to_unix_timestamp(tpep_pickup_datetime)
FROM yellow_2025_11
```
