When we look at the full query, it only shows $1, $2 or a1, a2 values instead of the exact values the database is using.

How can we see the values of our database queries?

This is intentional behavior that cannot be changed, because we require the queries to be parameterized as a prerequisite for the queries to be accepted. Most of our SDKs sanitize the queries automatically. We do this because our systems would not be able to handle the cardinality of all the queries if the actual values get sent and stored.
