在较旧的Oracle版本中编译的Java代码会在Oracle 12.2中产生编译错误

标签： java oracle compiler-errors

自Oracle 9以来我们一直在使用的一小段Java代码在Oracle 12.2中出现编译错误。

（看起来代码来自这里：https://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:439619916584）

12.2中有什么变化，所以我们需要更改我们的Java代码或需要授予的一些新权限吗？

编辑：使用SQL插入代码注释掉该行会导致正确的编译。也许这种语法不再可用？

create or replace and compile java source named "DirList"
as
   import java.io.*;
   import java.sql.*;
   import java.text.SimpleDateFormat;

   public class ChpDirList{

      public static void getList(String directory)
                         throws SQLException {

         File path = new File( directory );
         String[] list = path.list();
         String element;

         for(int i = 0; i < list.length; i++){

            element = list[i];

            String fpath=directory+"/"+list[i];
            File f = new File(fpath);
            long   len;

            String ftype;

            if (f.isFile()) {

               len   = f.length();
               ftype = "F";

            } else {

              len   = 0;
              ftype = "D";
           }

           #sql { INSERT INTO NGM_DIR_LIST (file_name, file_length, file_type, file_modified)
                  VALUES (:element, :len, :ftype, null) };
       }
      }
   }

事实证明，Oracle 12.2不再支持服务器端SQLJ。稍微改写一下代码就可以了。

create or replace and compile java source named "DirList" as

import java.io.*;
import java.sql.*;

public class ChpDirList {

 public static void getList(String directory)
 throws SQLException {

  Connection conn = DriverManager.getConnection("jdbc:default:connection:");
  String sql = "INSERT INTO NGM_DIR_LIST (file_name, file_length, file_type) values (?,?,?)";

  File path = new File(directory);
  String[] list = path.list();
  String element;

  for (int i = 0; i < list.length; i++) {

   element = list[i];


   String fpath = directory + "/" + list[i];

   File f = new File(fpath);

   long len;

   String ftype;


   if (f.isFile()) {

    len = f.length();
    ftype = "F";

   } else {

    len = 0;
    ftype = "D";
   }

   PreparedStatement pstmt = conn.prepareStatement(sql);
   pstmt.setString(1, element);
   pstmt.setLong(2, len);
   pstmt.setString(3, ftype);

   pstmt.executeUpdate();
   pstmt.close();
  }
 }
}
