peilinqian opened a new issue, #22823:
URL: https://github.com/apache/shardingsphere/issues/22823
### Which version of ShardingSphere did you use?
we find java version: java8, full_version=1.8.0_282, full_path=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.282.b08-1.el7_9.x86_64/bin/java
ShardingSphere-5.2.2-SNAPSHOT
Commit ID: dirty-631fdf40f87223e176abe5c851a51b3287b4d6de
Commit Message: Fix wrong decide result when execute same sharding condition subquery with sql federation (https://github.com/apache/shardingsphere/pull/22754)
Branch: https://github.com/apache/shardingsphere/commit/631fdf40f87223e176abe5c851a51b3287b4d6de
Build time: 2022-12-12T10:48:40+0800
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-Proxy
### Expected behavior
In the federation scenario，the select syntax of "order by nlssort" is supported.
### Actual behavior
In the federation scenario，the select syntax of "order by nlssort" does not support.
### Reason analyze (If you can)
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
```
select * from t_new_order o inner join t_merchant m using(merchant_id) where o.user_id > 10 and o.user_id < 15 order by nlssort(remark, 'nls_sort = generic_m_ci');
select * from t_new_order o inner join t_merchant m using(merchant_id) where o.user_id > 10 and o.user_id < 15 order by nlssort(remark, 'nls_sort = generic_m_ci') desc;
--view
create view select_view as select * from t_new_order where user_id <=25 and user_id>15 order by nlssort(remark, 'nls_sort = generic_m_ci'),order_id,user_id;
select * from select_view;
drop view select_view;
```
**the result of sharding**
```

Hi @peilinqian, thanks for reporting this issue.
`NLSSORT` is not supported by the Apache ShardingSphere SQL Federation implementation for openGauss. An explicit unsupported-function check has now been merged, so this SQL fails with a clear ShardingSphere exception instead of Calcite's generic function-resolution error.
Since native `NLSSORT` execution support is not planned, I am closing this issue as not planned.
