MS Acess不支持多个left join（语法错误（操作符丢失）在查询表达式 xx中）

如图：

 sql语句如下

select p.*,c.[name] as compName,s.[name] as sellerName from percentage p left join 
company c on c.id = p.compId left join seller s on s.id = p.sellerId

解决方法：

在第一个left join附近加()

select p.*,c.[name] as compName,s.[name] as sellerName from (percentage p left join 
company c on c.id = p.compId) left join seller s on s.id = p.sellerId

正确结果
