  select a.ywl,rs.rs  from temp a;

然後執行的語句：select a.ywl/rs.rs  from temp a  就會報以上的錯誤

 

通過各種博客記錄，提出報錯信息的博客很多，但解決問題不太好找，再找到 參考解決辦法原博客 得以解決；

解決語句1： select a.ywl/dec(rs.rs,25,2)    from temp a，即可進行解決

 

然後dec着實沒有見過，與decimal看起來像，類似，於是使用 cast(rs.rs as decimal(25,2))替代dec(rs.rs,25,2) ，發現也可以解決

解決語句2：select a.ywl/cast(rs.rs as decimal(25,2))   from temp a

 

發現解決方法着實難找，記錄以下，以便日後查詢。
