Table alias does not exist for subquery

[waterfountain1996]

Version

1.27.0

What happened?

SQLC fails to generate a query where I try to use a column from a subquery in a WHERE clause to compare against a query argument, which is a valid SQL syntax for SQLite. The same query compiles successfully I use a literal value instead of an argument.

P.S. I've tried reproducing it in the playground and it seems that it actually compiles successfully on v1.25.0 but not on v1.26 or newer.

Relevant log output

# package db
queries.sql:7:7: table alias "a" does not exist

Database schema

CREATE TABLE posts (
  id   BIGSERIAL PRIMARY KEY,
  tags TEXT -- JSON array of hashtags like ["#foo", "#bar"]
);

SQL queries

-- name: GetPostIDsByTag :many
SELECT DISTINCT a.id
FROM (
	SELECT p.id, ltrim(json_each.value ->> '$.name', '#') AS tag
	FROM posts p, json_each(p.tags)
) a
WHERE a.tag = 'foo';

Configuration

{
  "version": "2",
  "sql": [{
    "schema": "schema.sql",
    "queries": "query.sql",
    "engine": "sqlite",
    "gen": {
      "go": {
        "out": "db"
      }
    }
  }]
}

A simplified version of the query above

SELECT DISTINCT p.id
FROM posts p, json_each(p.tags) j
WHERE ltrim(j.value ->> '$.name', '#') = ?

gives the same table alias "j" does not exist error.
