Oracle数据库验证用户密码

Question

我希望用程序验证数据库用户。我需要检查用户给出的密码是否是该用户的密码，然后返回一个布尔值。我知道我可以使用带有替换选项的更改用户命令，但这实际上会改变用户的密码，该密码将作为密码更改记录在后端。我需要避免这种情况，只需验证密码是否正确。有没有办法做到这一点？

         String yourQry = "select * from yourtable where password = '"+pass+"' and username='"+username+"'" . 
      //Use this query when you are fetching data from user.
      Resultset rs;     // fetch your data in resultset
           if(rs.next()){
                 // if data got fetched 
                 return 1;
                 // 1 means true
            }
           else{
                    return 0; // 0 means false (No datafound) 
           }

          } `
