MariaDB Node.js Connecor占位符表名称

Question

我有表格“ ranking”和“ rankingprev”，我想在同一网页上显示它们。 （a）没有占位符的代码

  pool.query("select ROW_NUMBER() OVER (order by MName) as Rownum, MName, Tbp,Tgp,Tpp from members inner join ranking on members.id=Member_id and Rank='NM'")

（b）使用占位符的代码给出了sql语法错误（错误1064）

  pool.query("select ROW_NUMBER() OVER (order by MName) as Rownum, MName, Tbp,Tgp,Tpp from members inner join ? on members.id=Member_id and Rank='NM'", 'ranking')

在where子句中使用占位符没有问题

  pool.query("select ROW_NUMBER() OVER (order by MName) as Rownum, MName, Tbp,Tgp,Tpp from members inner join ranking on members.id=Member_id and Rank=?", 'NM')

看过documentation并在Google周围搜索，但无法解决。我可以做（b），怎么了？谢谢。
