Build Environment
SQLDelight version: 1.4.0
OS: macOS 10.15.5
Gradle version: 6.6
Kotlin version: 1.3.72
AGP Version: 4.0.1

Example:

song.sq

CREATE TABLE song(
    title TEXT,
    track_number INTEGER,
    album_id INTEGER
);

selectSongsByAlbumId:
SELECT * FROM song WHERE album_id = ?;

This compiles to the following:

SongQueries.kt

interface SongQueries : Transacter {
  fun <T : Any> selectSongsByAlbumId(album_id: Long?, mapper: (
    title: String?,
    track_number: Long?,
    album_id: Long?
  ) -> T): Query<T>

  fun selectSongsByAlbumId(album_id: Long?): Query<Song>
}

Everything works correctly so far. Adding another .sq file with a view that selects all columns from the table changes things:

first_song_in_album.sq

CREATE VIEW first_song_in_album AS
SELECT * FROM song WHERE track_number = 1;

This causes the selectSongsByAlbumId query to be compiled with the wrong return type:

SongQueries.kt

interface SongQueries : Transacter {
  fun <T : Any> selectSongsByAlbumId(album_id: Long?, mapper: (
    title: String?,
    track_number: Long?,
    album_id: Long?
  ) -> T): Query<T>

  fun selectSongsByAlbumId(album_id: Long?): Query<First_song_in_album> // Instead of Query<Song>
}

The First_song_in_album type does not exist and the build fails because of this:

SongQueries.kt: (16, 52): Unresolved reference: First_song_in_album

Additional information

• The IDE plugin generates the return type correctly as Query<Song>. Only when building with the Gradle plugin does this problem occur.
• The problem only occurs when both the selectSongsByAlbumId query and the first_song_in_album view select all columns (*) from the table.
• The problem only occurs when the query and the view are in separate files.
