版本：V2.0.9

现象：

第6行能够正常插入进去，但三方工具或者jdbc协议查询必定报错，mysql client查询正常。

复现步骤：

use ods_dev;
CREATE TABLE if not exists `test_empty_value_20250306`
(
    `bill_pk`                      varchar(150)  NOT NULL COMMENT '任务流水主键',
    `flow_proc_end_time`           datetime      NULL COMMENT '流程结束时间'
)
    ENGINE = OLAP
    UNIQUE KEY(`bill_pk`)
    COMMENT '流程详情表'DISTRIBUTED BY HASH(`bill_pk`) BUCKETS 1
    PROPERTIES ("is_being_synced" = "false","storage_format" = "V2",
    "enable_unique_key_merge_on_write" = "true",
