Hi!

There is nothing predefined for gda_column_get_attribute for the
primary_key property that was available in v3. How can I get this?

 
It has been removed because:
* having a column marked PK in a data model did not mean the column would be unique and not null in the reult set (for example if you have a join in the SELECT)
* it can be time consuming to compute it.

The gda_data_select_compute_columns_attributes() method computes the column attibutes for some of the attributes, and you can use it as an example of how to get the information you want.

Regards,

Vivien
