2024-11-01 10:24:54.549 [ERRO] [prometheus] queryable_offload.go:208 offload querier sql: SELECT time(time, 20, 1,'', 16) AS timestamp,tag,Percentile(toUnixTimestamp(time),1) as _last_timestamp,Percentile(toUnixTimestamp(time),0) as _first_timestamp,Percentile(value, 0) as _first_value,Max(value) as value FROM process_runtime_jvm_gc_duration_sum WHERE (time >= 1730405616 AND time <= 1730427516) AND tag.job = 'java' AND tag.instance REGEXP '^11.244.222.18:9567$' GROUP BY tag,timestamp ORDER BY timestamp desc LIMIT 1000000

Look at the code where the problem is with the parseSelectAlias method in clickhouse.go,
This situation may need to be handled according to the BinaryFunction.
查看代码发现问题出在clickhouse.go的 parseSelectAlias方法，可能需要按照BinaryFunction进行处理

How to reproduce

When you use Prometheus Range to query APIs, set operator-offloading=true
Use the increase function in promql, for example: increase(process_runtime_jvm_gc_duration_sum{job="java",instance=~"^11.244.222.18:9567$"}[5m])
