Answer 1

由于两个表： archives和jobrt包含columnName typeID ，因此需要指定值来自的tableName，例如

SELECT    id
        , pubdate
        , jobrt.typeid
        , aid
        , jobname
        , jobdepart
        , jobplace
        , jobnumber
        , jobcontact
FROM    archives
        RIGHT JOIN jobrt
            ON archives.id = jobrt.aid
WHERE   jobrt.typeid = 19

Answer 2

您应该确定select中的哪个表，如下所示：

select archives.id,archives.pubdate, archives.typeid,aid,jobname,jobdepart,jobplace,jobnumber,jobcontact from
  archives right join jobrt on id=aid where typeid=19
