Office 365 DLP on Premise and Cloud same time...
In a single word - No. The DLP controls Office 365 offers are way ahead of the on-premises ones, so even if there was a single policy that spans cloud and on-premises resources, it would be limited in some features.
And no on the SQL question, none of the Microsoft offerings covers DLP for that scenario.
DLP policies are matched by examining the cloud search index. So if you can get something into the search index then potentially it can be examined for DLP. To get on premise SharePoint content into the cloud search index you need to set up cloudSSA hybrid search which can be done relatively easily if you're SP2013 or SP2016 on premise (not Exchange on premise). eDiscovery and content search in Security & Compliance centre definitely picks up this on prem content so don't see why DLP policies would not too. This would then give you one portal at least for all the SharePoint content. See attached image for a conceptual view of he crawl process.
