WHERE子句不起作用的Hive查询（ORC表）

Question

正在查询的表格：

col_name    data_type   comment
# col_name              data_type               comment             
number  int Format: <integer> | Example: 0 | Description: Ascending number series

细节：

select number from hfe_reference.dim_number limit 10;

这有效：

select number from hfe_reference.dim_number where number < 5;

这不，查询运行，但结果为空：

WHERE

已使用其他where number = 2条款，例如where number between 0 and 5， import io.circe._, io.circe.generic.auto._, io.circe.parser._, io.circe.syntax._ case class Test(a: Map[String,String]) val map = Test(Map("a"->"1","2"->"2")).asJson val hcursor = map.hcursor val m = hcursor.downField("a").as[Map[String,String]] println(m) // Right(Map(a -> 1, 2 -> 2))

为什么WHERE子句导致空结果集？
