I see.
> Please try all the variants
Our Apache Spark supports all the following 4 cases.
- interval 1 day
- interval 1 days
- interval '1' day
- interval '1' days
```scala
scala> sql("select current_timestamp + INTERVAL 1 DAY, current_timestamp +
INTERVAL 1 DAYS, current_timestamp + INTERVAL '1' DAY, current_timestamp +
INTERVAL '1' DAYS").show
+--------------------------------------------------------+--------------------------------------------------------+--------------------------------------------------------+--------------------------------------------------------+
|CAST(current_timestamp() + interval 1 days AS
TIMESTAMP)|CAST(current_timestamp() + interval 1 days AS
TIMESTAMP)|CAST(current_timestamp() + interval 1 days AS
TIMESTAMP)|CAST(current_timestamp() + interval 1 days AS TIMESTAMP)|
