Could you, please, put this test on the signature and remove the else?

I mean something like:
multi method translate(Red::AST::In $_ where .right.value ~~ Positional, $context?) {There was a problem hiding this comment.
But, instead of testing the right's value type, it would be better to test if it's an Red::AST::Value and if its .type is Positional.
multi method translate(Red::AST::In $_ where .right ~~ Red::AST::Value && .right.type ~~ Positional, $context?) {

Why change to use in (SELECT 0 WHERE false)? why not in ()?

Because In Pg, the in () will raise error, So, we should add placehoder statement to select "nothing".

In that way, maybe we could do an:
multi method translate(Red::AST::In $_ where .right ~~ Red::AST::Value && .right.type ~~ Positional && .right.elems, $context?) {?

Isn't it common? Couldn't it be on CommonSQL?

It's common, But It's strange that it works in SQLite.

If you fix one of my errors (https://github.com/FCO/Red/blob/master/lib/Red/Driver/CommonSQL.pm6#L521) changing "?" to self.wildcard, you could just use the self.translate: .right, $context

Could you, please, add a test for json and jsonb?
for SQLite, it re-fetches the row from the model by using LastInsertedRow
class, Then the `.row{@ids}` does the right thing all the time. But in
postgres, the $data will filled by `INSERT INTO table xxx RETURNING *` after
the RETURNING, we'll $data with column names with underscores.
So, in the pg case, We convert the $data structure according to the model, make
$data look like the same as fetched with LastInsertedRow class.

This test is failing here. For Red:api<2> you need to set the :model<> for is referencing or :model-name<> in this case... and receive the model type as parameter:
has Int $.parent_if is column{ :references{ .id }, :nullable };2 participants
Hi, These 3 patches add method column-values, and some small fixes for Red::Driver::Pg
Thanks!
