StarRocks直连BE查询数据缺陷

[motto1314]

【简述】
使用直连BE查询（查询QueryPlan后，使用open_scanner/get_next获取数据），出现column name为空的问题

【StarRocks版本】2.3.3

【详述】
表结构：
CREATE TABLE test.table1 (
id varchar(10) NOT NULL COMMENT “”,
price decimal64(17, 6) NULL COMMENT “”,
flag int(11) NULL COMMENT “”
) ENGINE=OLAP
PRIMARY KEY(id)
COMMENT “OLAP”
DISTRIBUTED BY HASH(id) BUCKETS 20
PROPERTIES (
“replication_num” = “1”,
“in_memory” = “false”,
“storage_format” = “DEFAULT”,
“enable_persistent_index” = “false”
);
统计：
select * from test.table1 正确
select id,price from test.table1 正确
select * from test.table1 where flag=0 正确
select id,price,flag from test.table1 where flag=0 正确
select id,flag from test.table1 where flag=0 正确
select id,price from test.table1 where flag=0 错误
即：当筛选列（id,price）不包括过滤列（flag）时会有问题

正确截图：
select id,price,flag from test.table1 where flag=0

select id,price from test.table1

异常截图:
select id,price from test.table1 where flag=0

是否有执行计划解析的情况有关系？

explain select id,price from test.table1
