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.
