Description

Version

1.30.0

What happened?

It's not possible to compile the query if id column is in final WHERE condition. The query works towards PostgreSQL 17.5.

Maybe similar to #3924 and #3730

Relevant log output

sqlc generate failed.

# package 
query.sql:15:7: column reference "id" is ambiguous

Database schema

CREATE TABLE employee (
  id   BIGSERIAL PRIMARY KEY,
  name text      NOT NULL,
  parent_id bigint,
  deleted timestamp
);

SQL queries

-- name: GetEmployeeTree :many
WITH RECURSIVE parent_tree AS (
    SELECT d1.id, d1.name, d1.parent_id
    FROM employee d1
    WHERE d1.id = $1
      AND d1.deleted IS NULL
    UNION ALL
    SELECT d2.id, d2.name, d2.parent_id
    FROM employee d2
        INNER JOIN parent_tree pt ON d2.id = pt.parent_id
    WHERE d2.deleted IS NULL
)
SELECT id, name
FROM parent_tree
WHERE id != $1
ORDER BY id DESC;
