MSSql (Compact) DELETE-Query with JOIN

I have this query. I want to delete all entities from AgentsResultLinks-Table, that don't have a link to a entity in Results-Table. I want a solution with one single query. I got an error caused by '*'.

DELETE AgentResultLinks.*
FROM AgentResultLinks LEFT JOIN Results 
ON AgentResultLinks.ResultID = Results.ID
WHERE Results.ID IS NULL

Can someone help me to convert this query in a vaid mssql query for compact database ? The Performance is very important.

Solution 
  • DELETE FROM AgentResultLinks 
where ResultID not in(select distinct ID from Results)
