[GitHub] [incubator-doris] killxdcj opened a new issue #7084: [Bug] If aggregate columns contain expr, CacheAnalyzer will throw exception
killxdcj opened a new issue #7084:
URL: https://github.com/apache/incubator-doris/issues/7084
### Search before asking
- [X] I had searched in the [issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and found no similar issues.
### Version
doris-0.14.0
### What's Wrong?
When partition_cache is enabled, if Query's aggregate columns contain expression, CacheAnalyzer will throw exception and causes the query to fail.
### What You Expected?
should not throw exception
### How to Reproduce?
1. Create a table with more then one partition, and insert some data to the table.
CREATE TABLE test (
k1 bigint(20) NOT NULL COMMENT "",
k2 varchar(255) NOT NULL COMMENT "",
k3 date NOT NULL COMMENT "",
v1 varchar(255) NOT NULL COMMENT ""
) ENGINE=OLAP
DUPLICATE KEY(k1, k2, k3)
COMMENT "OLAP"
PARTITION BY RANGE(k3)
(PARTITION p20210519 VALUES [('2021-05-19'), ('2021-05-20')),
PARTITION p20210520 VALUES [('2021-05-20'), ('2021-05-21')),
PARTITION p20210521 VALUES [('2021-05-21'), ('2021-05-22'))
DISTRIBUTED BY HASH(k1, k2) BUCKETS 3
PROPERTIES (
"replication_num" = "3"
);
2. set enable_partition_cache=true and execute the flowing query.
`select char_length(k1) as len, sum(1) from test group by len`
3. Exception in FE log
