[Bug] Materialized selector chooses the error index when Count(*) #4065
Description
Describe the bug
Query: Select count(*) from table;
Error: errorCode = 2, detailMessage = field name is invalid. field = boolean column
To Reproduce
Steps to reproduce the behavior:
- create table
CREATE TABLE `ads_feed_card_pd_info`(
`member_id` bigint COMMENT '用户的id',
`client_id` varchar(36) COMMENT '设备id',
`hash_id` varchar(32) COMMENT '用户hashid',
`p_date` DATE,
`is_client_id_day_new` boolean COMMENT '是否是新设备',
...
)
ENGINE=olap
DUPLICATE KEY(member_id, client_id, hash_id)
PARTITION BY RANGE (p_date)
(
PARTITION p1 VALUES LESS THAN ("2017-07-01"),
PARTITION p2 VALUES LESS THAN ("2017-07-02"),
PARTITION p3 VALUES LESS THAN ("2017-07-03"),
PARTITION p4 VALUES LESS THAN ("2017-07-04"),
PARTITION p5 VALUES LESS THAN ("2017-07-06"),
PARTITION p6 VALUES LESS THAN ("2017-07-07"),
PARTITION p7 VALUES LESS THAN ("2017-07-08"),
PARTITION p8 VALUES LESS THAN ("2017-07-09"),
PARTITION p9 VALUES LESS THAN ("2017-07-10")
)

The incorrect index has been chosen.
Expected behavior
The index which include field is_client_id_day_new should be chosen.
