Delete messages in service broker queue

Question

I\'d like to clear my queue in SQL Server Management Studio, but I don\'t want to delete the whole queue just the content in the queue (the messages).

Answer 1

while(1=1)
begin
    waitfor (
        receive top(1)
        conversation_group_id
        from kartokumaqueue2), timeout 1000;

        if(@@ROWCOUNT = 0) break;
end
