jsonb_agg issue

[Антонио Антуан]

Hi guys.

I'm using sqlalchemy 1.1.13, want to construct that query:

select o.*, jsonb_agg(ou.*) from "Orders" o left join "OrderUIN" ou on ou."OrderID" = o."OrderID" group by o."OrderID"

I tried that options:

- func.jsonb_agg(OrderUINTable), got select o.*, jsonb_agg() from "Orders"... Empty argument for the function, as you can see.

- func.jsonb_agg(OrderUINTable.columns.values()), got can't adapt type 'Column'

- func.jsonb_agg(OrderUINTable.alias), got TypeError: self_group() got an unexpected keyword argument 'against'

How can I implement it?

Another one fail:

func.jsonb_agg(*models.OrderUINTable.c.values()) - PG error: "function jsonb_agg(integer, text, numeric, text, text, text, text) does not exist"

Ok, that works almost fine:

>>> func.jsonb_agg(literal_column(models.OrderUINTable.name + '.*'))

'jsonb_agg(OrderUIN.*)'

The problem is OrderUIN. It must be quoted: jsonb_agg("OrderUIN".*)
