A complete answer to your question is difficult. When you ask "can I get" do you want to know if it is possible or do you want to know if it will probably happen? I will try to explain in simple words.
(The EU/Schengen states retain the sovereign right to grant residency status, regardless of adverse information from other partner nations, or even in their own databases. That does not mean they will normally override the visa decisionmaking process that way.
A 30-month conviction in Denmark means a quite serious offense or many repeat offenses, they do not give multi-year prison sentences lightly. We do not know if there are reasons to make a visa more likely, family reunifications or the like.)
