Hi,
I work for Tableau and we need to collect metadata about unique constraints/primary keys.
The ODBC driver doesn't implement the API which we usually use to collect this information (SQLStatistics).
So we are querying the constraint_columns view directly.
This view reads from two tables:
v_internal.vs_constraint_columns
and
v_internal.vs_columns
We don't need the information from the second table (not null contraints).
I wanted to know if it is safe to read the information from v_internal.vs_constraint_columns.
Is the schema for this table subject to change?
