[GitHub] [shardingsphere] strongduanmu opened a new issue #11741: Federate executor engine does not support dialect database function
strongduanmu opened a new issue #11741:
URL: https://github.com/apache/shardingsphere/issues/11741
## Bug Report
### Which version of ShardingSphere did you use?
master branch
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-Proxy
### Expected behavior
Execute sql success. Following is the sql, `t_order` is a sharding table.
```sql
SELECT order_id, CONCAT('sum:', sum(cnt)) FROM (
SELECT order_id, user_id, COUNT(1) AS cnt FROM t_order GROUP BY order_id, user_id
) a GROUP BY order_id;
```
### Actual behavior
```
ERROR 1815 (HY000): Internal error: Error while preparing statement [SELECT order_id, CONCAT('sum:', sum(cnt)) FROM ( SELECT order_id, user_id, COUNT(1) AS cnt FROM t_order GROUP BY order_id, user_id ) a GROUP BY order_id]

According to the [official documentation](https://calcite.apache.org/docs/reference.html#dialect-specific-operators), the `CONCAT` function is a dialect operation and is not included in standard SQL. We need to enable the fun parameter to support this operation.
