要解决该错误，必须从GROUP BY子句中删除别名。另外，如果表中有date列，则不需要CASTs，查询可以重新编写为：
SELECT
to_char(START_TIME,'YYYY') START_BY_YEAR ,
to_char(END_TIME,'YYYY') END_BY_YEAR ,
to_char(START_TIME,'MM.YYYY') START_BY_MONTH,
to_char(END_TIME,'MM.YYYY') END_BY_MONTH,
to_char(START_TIME,'DD.MM.YYYY') START_BY_DAY,
to_char(END_TIME,'DD.MM.YYYY') END_BY_DAY,
COUNT(*) as count,
round(100*ratio_to_report(count(*)) over (), 4) percentage
FROM TABLE_NAME
WHERE to_char(START_TIME,'MM.YYYY')='12.2020'
and to_char(END_TIME,'MM.YYYY')='12.2020'
GROUP BY
to_char(START_TIME,'YYYY') ,
to_char(END_TIME,'YYYY') ,
to_char(START_TIME,'MM.YYYY') ,
to_char(END_TIME,'MM.YYYY') ,
to_char(START_TIME,'DD.MM.YYYY') ,
to_char(END_TIME,'DD.MM.YYYY')
order by
START_BY_YEAR desc,
END_BY_YEAR desc,
START_BY_MONTH desc,
END_BY_MONTH desc,
START_BY_DAY desc,
END_BY_DAY desc
用这样的表：
create table table_name as
(
select date '2020-12-01' start_time,
date '2020-12-02' end_time
from dual
);
该查询给出：
START_BY_YEA END_BY_YEAR START_BY_MON END_BY_MONTH START_BY_DAY END_BY_DAY COUNT PERCENTAGE
------------ ------------ ------------ ------------ ------------ ------------ ----- ----------
2020 2020 12.2020 12.2020 01.12.2020 02.12.2020 1 100

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.

我上面已经提到过，数据类型为date，您尝试重新运行，但是我再次遇到错误ORA-00904：“ END_BY_DAY”：无效标识符00904。00000-“％s：无效标识符” *原因：*操作：行错误：19列：1
刚刚编辑以显示完整的工作查询，简化了
非常感谢它的工作，我对错误的理解
