   ### Version

   ### What's Wrong?
   
   cast函数作谓词下推的时候，date类型会在后面补全 00:00:00。
   查询sql如下:
   select * from test_table orapd where cast(ac_time as date) = '2023-01-29'
   建表语句：
   CREATE TABLE `test_table` (
     `id` int(11) NULL COMMENT "唯一标识",
     `ac_time` datetime NOT NULL COMMENT "采集时间",
   ) ENGINE=OLAP
   UNIQUE KEY(`id`)
   COMMENT "test"
   DISTRIBUTED BY HASH(`id`) BUCKETS 12
   PROPERTIES (
   "replication_allocation" = "tag.location.default: 3",
   "in_memory" = "false",
   "storage_format" = "V2"
   );
   
   explain 如下图
