If you see the square icon next to a field in the field picker, it means that Omni doesn’t recognize the data type of that field.

You’ll still be able to select that field and view it in the table, but to interact with it further, you may need to transform the field by `cast()`ing it in the model file (e.g. `cast(${order_items.date} as timestamp)`.
