Try this when `spark.sql.nestedSchemaPruning.enabled` is on?
```SQL
withTable("t1") {
spark.sql(
"""
|Create table t1 (`id` INT,`CoL1` STRING,
|`coL2` STRUCT<`a`: TIMESTAMP, `b`: INT, `c`: ARRAY<DATE>>,
|`col3` INT,
|`col4` INT,
|`Col5` STRUCT<`a`: STRING, `b`: STRUCT<`a`: INT, `b`:
ARRAY<INT>, `c`: INT>, `c`: INT>)
|USING parquet
""".stripMargin)
spark.sql("SELECT id from t1 where col2.b < 7").count()
}
```
