MSSql(Compact)DELETE-Query with JOIN

Question

我有这个问题.我想从AgentsResultLinks-Table中删除所有实体,这些实体没有指向Results-Table中实体的链接.我想要一个单一查询的解决方案.我收到了'*'引起的错误.

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

有人可以帮助我在紧凑型数据库的vaid mssql查询中转换此查询吗？表演非常重要.

Answer 1

只是删除.*从AgentResultLinks.*

DELETE Agent
FROM AgentResultLinks Agent 
LEFT JOIN Results R
       ON Agent.ResultID = R.ID
WHERE R.ID IS NULL;

请参见DELETE语法:DELETE(Transact-SQL)

请参见SQLFiddle示例

Answer 2

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