> val clone = spark.cloneSession()
> clone.conf.set("spark.sql.legacy.interval.enabled", "true")
> clone.sql("select '2023-01-01'+ INTERVAL 1 YEAR as b").show()
> clone.sql("select '2023-01-01' as a").selectExpr("a + INTERVAL 1 YEAR as
> b").show() {code}
> The first one can be executed successfully, but the second one cannot be
> executed successfully.
> Because selectExpr and sql use different sparkSession conf.
