I'm struggling retrieving more than one column from database. If I use a query with just a single colum, like the following:
It works as expected, but if I use a single query to have both the parameters, the first one return `null`
Here `shapes` is `null`
There `annotations` is `null`. If I select all the columns with `*` both `annotations` and `shapes` results `null`, and the other columns returns their values, any ideas on why this happens? Thanks! ------------------------------------------------------------------------------------------ |
