Question

我尝试在oracle数据库中运行此查询但不幸的是我收到此错误请帮助我:(

java.sql.SQLException：ORA-01460：请求未实现或不合理的转换现在问题解决了，我有另一个例外：我改变了这一行

 pstmt.setBinaryStream(7, fis, (int) file.length());

与

 pstmt.setBinaryStream(7, fis, (long) file.length());

线程“AWT-EventQueue-0”中的异常java.lang.AbstractMethodError：oracle.jdbc.driver.OraclePreparedStatement.setBinaryStream（ILjava / io / InputStream; J）V

对于文本文件没有问题，但是当我尝试上传JPG文件时，我收到此错误。

    PreparedStatement pstmt = 
                          conn.prepareStatement("INSERT INTO PM_OBJECT_TABLE( " +
                          "N_ACTIVITY_ID, V_NAME,N_SIZE, D_MODIFY,N_CATEGORY, N_NODE_ID ,O_OBJECT) " +
                          " VALUES ( ? , ? , ? , ? , ? , ? ,?)");
                pstmt.setLong(1, N_ACTIVITY_ID);
                pstmt.setString(2, file.getName());
                pstmt.setLong(3, file.length());
                java.util.Date date = new java.util.Date(); 
                java.sql.Date sqlDate = new java.sql.Date(date.getTime()); 
                pstmt.setDate(4,sqlDate);
                pstmt.setInt(5, N_CATEGORY);
                pstmt.setLong(6, N_NODE_ID);
                pstmt.setBinaryStream(7, fis, (int) file.length());
                pstmt.executeUpdate();

Answer 1

java.lang.AbstractMethodError：com.mysql.jdbc.ServerPreparedStatement.setBinaryStream（ILjava / io / InputStream; J）V

要解决此问题，您需要更改对setBinaryStream的调用，以便将最后一个参数作为整数而不是long传递。

我在面对同样的问题时在博客中找到了引用

就像上面的PreparedStatement.setBinaryStream（）有三个重载方法

我们应该使用setBinaryStream（columnIndex，InputStream，（（（（（（（（（INT））））））））

否则，可能会导致错误

Answer 2

我也遇到过这个问题，代码正常工作，然后突然出现了这个错误。

我正在使用Glassfish 3运行Netbeans 8.0.2 在GlassFish \ Glassfish \ libs文件夹中，我有2个ojdbc文件ojdbc6.jar和ojdbc14.jar 似乎即使ojdbc6被包含在项目库中，ojdbc14也被加载了。

我停止将glassfish重命名为ojdbc14.jar到ojdbc14.jar.bak，然后清理并构建和部署项目。

问题已解决。

我通过之前的建议解决了我的问题：

public String insertBineryToDB(long N_ACTIVITY_ID,int N_CATEGORY,long  N_NODE_ID ,FileInputStream fis , java.io.File file) {
    Statement statement;
    try {
        //conn.close();
       // N_ACTIVITY_ID, V_NAME,N_SIZE, D_MODIFY,N_CATEGORY, N_NODE_ID ,O_OBJECT
        PreparedStatement pstmt = 
                              conn.prepareStatement("INSERT INTO PM_OBJECT_TABLE( " +
                              "N_ACTIVITY_ID, V_NAME,N_SIZE, D_MODIFY,N_CATEGORY, N_NODE_ID ,O_OBJECT) " +
                              " VALUES ( ? , ? , ? , ? , ? , ? ,empty_blob())");



InputStream bodyIn = fis;

                pstmt.setLong(1, N_ACTIVITY_ID);
                pstmt.setString(2, file.getName());
                pstmt.setLong(3, file.length());
                java.util.Date date = new java.util.Date(); 
                java.sql.Date sqlDate = new java.sql.Date(date.getTime()); 
                pstmt.setDate(4,sqlDate);
                pstmt.setInt(5, N_CATEGORY);
                pstmt.setLong(6, N_NODE_ID);
                //pstmt.setBinaryStream(7, bodyIn,(int) file.length());
                pstmt.executeUpdate();
                conn.commit();

    PreparedStatement stmt2 = conn.prepareStatement(" select O_OBJECT from PM_OBJECT_TABLE where N_ACTIVITY_ID = ? for update ");
    stmt2.setLong(1, N_ACTIVITY_ID);
    ResultSet rset = stmt2.executeQuery();

    FileInputStream inputFileInputStream    = new FileInputStream(file);
    rset.next();
    BLOB  image = ((OracleResultSet) rset).getBLOB("O_OBJECT");

    int bufferSize;
    byte[]  byteBuffer;
    int bytesRead = 0;
    int bytesWritten = 0;
    int totBytesRead = 0;
    int totBytesWritten = 0;

    bufferSize = image.getBufferSize();
    byteBuffer = new byte[bufferSize];

    OutputStream blobOutputStream = image.getBinaryOutputStream();

    while ((bytesRead = inputFileInputStream.read(byteBuffer)) != -1) {
      // After reading a buffer from the binary file, write the contents
      // of the buffer to the output stream using the write()
      // method.
        blobOutputStream.write(byteBuffer, 0, bytesRead);
        totBytesRead += bytesRead;
        totBytesWritten += bytesRead;
    }
  inputFileInputStream.close();
  blobOutputStream.close();

  conn.commit();
  rset.close();
  stmt2.close();

 String output =  "Wrote file " + file.getName() + " to BLOB column." +
                  totBytesRead + " bytes read." +
                  totBytesWritten + " bytes written.\n";
    return output;
} catch (Exception e) {
    e.printStackTrace();
    return "Wrote file " + file.getName() + " to BLOB column failed." ;
}
}

使用java.sql.PreparedStatement.setBinaryStream（int parameterIndex，InputStream x） - 2个参数，而不是3个。
