What happened?

updated from v1.17.2 and get the following log when i run sqlc generate. I use brew to install sqlc and it looks like old versions are not being tracked in brew so we cannot downgrade.

Relevant log output

sqlc generate

Sorry about that. We'll need to take a deeper look, but in the meantime if you need an older version you can grab a pre-built binary from the v1.17.2 GitHub release page or from https://downloads.sqlc.dev/

[andrewmbenton]

The bug is an invalid type assumption in internal/compiler/output_columns#510.

I can fix this with a type assertion and an error bail-out when it fails, but I'm not sure that's the correct thing to do. The offending commit looks like it was part of this PR by @haines and @kyleconroy so hopefully one of them can advise.

[kyleconroy]

@mwhitm We're going to fix the panic, but v1.19.0 will still return an error. To fix the regression, we'll need a bit more information from you. Can you include the query (with database tables) that's causing the issue?

[mwhitm]

Hi Kyle, it happens when i run sqlc generate (needed to build our application). For completeness i also ran the other cli functions and get the same thing.

So it's not on a query per se but building generating the files. I am using postgres.

[andrewmbenton]

@mwhitm the bug occurs as part of a query parsing step, so it would be ideal if we had access to the offending query or queries. I can fix the panic, but I would also like to ensure that sqlc output is correct for your queries.

I'd be happy to take a look at your queries and see if I can figure it out, if you can attach your query.sql (or whatever files contain your queries) to an email to hello@sqlc.dev.

[andrewmbenton]

Digging through the pganalyze source a bit led me to try a few different test-cases, and I have one that triggers this panic (using postgres):

SELECT * FROM CURRENT_DATE;

I'll work on an endtoend test and a bug fix using this as a starting point.

I have a similar issue with 1.19.0.

(select id
from chat
where id < ? or id = (select min(id) from chat)
order by id desc
limit 1)
union all
(select id
from chat
where id > ? or id = (select max(id) from chat)
order by id asc
limit 1);

Commenting this query out works like a charm, but generating with this query gives the following error:

panic: interface conversion: ast.Node is *ast.SetOprSelectList, not *ast.SelectStmt

When installing sqlc via go install I also get the following error:

# github.com/kyleconroy/sqlc/cmd/sqlc
/usr/bin/ld: warning: x86_64.o: missing .note.GNU-stack section implies executable stack
/usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker

But sqlc version and go generate work fine without the above query.

UPDATE: Using the precompiled binary also gives the same error.

sqlc playground does not give me any issues with this query: https://play.sqlc.dev/p/d2f08367622724c2eb6f9402ef6f5a70e035e5279774d3ad3f4accd75a59a7ee

1.14.0 the previous version we used also returns the same error panic: interface conversion: ast.Node is *ast.SetOprSelectList, not *ast.SelectStmt with the UNION ALL query.
