我们自 Oracle 9 以来一直使用的一小段 Java 代码在 Oracle 12.2 中出现编译错误。
(看起来代码源自这里:https://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:439619916584)
12.2 中是否发生了某些变化，因此我们需要更改 Java 代码或需要授予一些新的权限？
编辑:注释掉带有 SQL 插入代码的行会导致正确的编译。也许该语法不再可用？
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) };
}
}
}

最佳答案
事实证明，Oracle 12.2 不再支持服务器端 SQLJ。对代码进行一点重写就可以了。
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();
}
}
}
