----------------------------------
Hi @Haris Sattar,
I tried to reproduce the problem based on the description, but it seems to work
as expected on my end (I tested with the latest {{main}} branch).
Could you please provide a minimal reproducible example, such as the exact SQL
snippet, configuration, or a test case? That would help me investigate further.
Thanks!

> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.39.0
> Reporter: Haris Sattar
> Assignee: krooswu
> Priority: Major
> Labels: pull-request-available
>
> *Example:*
> Input RelNode tree: a correlated scalar subquery where the outer table is
> table_a and the inner table is table_b, correlated on column "id".
> *Expected SQL output:*
> SELECT "id",
> (SELECT SUM("value") FROM "table_b" AS "t1"
> WHERE "id" = "t"."id") AS "total_value"
> FROM "table_a" AS "t"
> *Actual SQL output:*
> SELECT "id",
> (SELECT SUM("value") FROM "table_b" AS "t1"
> WHERE "id" = "t0"."id") AS "total_value"
> FROM "table_a" AS "t"
> The correlation reference emits "t0"."id" but the outer table's FROM clause
> says AS "t". "t0" does not exist in the query. The SQL is invalid and will be
> rejected by the execution engine.
