[GitHub] [incubator-doris] morrySnow opened a new issue, #9740: [Enhancement] change Doris's query organization syntax to standard sql
morrySnow opened a new issue, #9740:
URL: https://github.com/apache/incubator-doris/issues/9740
### 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.
### Description
Current, we process `order by` and `limit` in Doris only way:
https://github.com/apache/incubator-doris/blob/d97e2b1eb21b1026ef95f0cb5b87e0138c704de8/fe/fe-core/src/main/cup/sql_parser.cup#L3174-L3191
I think we need to change it behavior to standard SQL. query organization need to be executed at last.
### Solution
change syntax to match standard sql:
```
query = ctes? queryTerm queryOrganization
queryTerm = queryPrimary | setOperation
queryPrimary = selectClause fromClause? whereClause? aggregationClause? havingClause? windowClause?
| values
| LEFT_PAREN query RIGHT_PAREN
```
