I'm new to writing queries but I thought this SENT query would be simple. I'm just trying to get All sends for the last 30 days. But when i run the query, nothing populates in the DE and nothing populates in the Action Log. I feel like I'm SO close but as I've been building out my automation I keep running into Super niche errors. Do I *need* a primary key? Any help would be welcome!!!

Here's my query: 
SELECT
AccountID, 
OYBAccountID,
JobID,
ListID,
BatchID,
SubscriberID,
SubscriberKey,
EventDate,
Domain,
TriggererSendDefinitionObjectID,
TriggeredSendCustomerKey

FROM _Sent

WHERE  Eventdate > Dateadd(day, -30, Getdate())  

**Here are my DE values:**
