thswlsqls opened a new issue, #40067:
URL: https://github.com/apache/shardingsphere/issues/40067
## Bug Report
### Which version of ShardingSphere did you use?
master @ 7712a28fffe
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
Both (MySQL dialect)
### Expected behavior
An `ANY`/`ALL`/`SOME` subquery can reference a table alias declared two or
more query levels out, as `EXISTS` and scalar subqueries already can.
### Actual behavior
Binding fails with `ColumnNotFoundException: Unknown column 'o.user_id' in
'where clause'`.
### Reason analyze (If you can)
`ExpressionSegmentBinder.bind()` passes only `tableBinderContexts` to
`QuantifySubqueryExpressionBinder`, which forwards it to
`SubquerySegmentBinder` as the outer contexts. The `ExistsSubqueryExpression`
and `SubqueryExpressionSegment` branches merge `outerTableBinderContexts` with
`tableBinderContexts` first, so the quantified branch drops every scope above
the current one. #36135 fixed the same loss in `NotExpressionBinder`.
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule
configuration, when exception occur etc.
Bind this MySQL statement (the quantified subquery must be nested at depth 2
or more; a non-nested correlated `ALL` works):
```sql
SELECT o.order_id FROM t_order o WHERE EXISTS (SELECT 1 FROM t_order_item i
WHERE i.order_id = o.order_id
AND i.price > ALL (SELECT p.price FROM t_product p WHERE p.user_id =
o.user_id))
```
