Parameters: Equivalent of JDBC's setArray()

[nevi-me]

I'm trying to run something like:

select * from roles where role_group in ('a', 'b', 'c');

Is there a way of running?

connection.query(
    "SELECT * FROM roles WHERE role_group in @P1",
    &[???]
)

No not currently.
The closest would be to manually unroll and build IN(@P1, @P2, ...) as SQL and then pass multiple parameters.

I'll use a manual unroll for now, but it's something I'd like to work on with some guidance. Can you point me in the right direction? I can work on this in the coming days/weeks

I doubt there's a nice way to support this, not even the microsoft JDBC driver does:

There setStructured which accepts SQLServerDataTable. But it requires to define type in the database.
