java - 如何将 ascii 流绑定(bind)到准备好的语句

Question

我正在测试 official teradata website 中的快速加载示例代码.为了谨慎起见，我使用了位于其 samples.jar here 上的示例 FastLoad1.csv

当我运行这个示例代码时，我在这一行中得到一个错误

  pstmtFld.setAsciiStream(1, dataStream, -1); // This method is not implemented

setAsciiStream 必须如何与准备好的语句一起使用？

我是否正确使用了 setAsciiStream？

Answer 1

我尝试编译示例 T20208JD，只是修改了 DNS/用户/密码，它在我的 Mac 上运行顺利。所以 pstmtFld.setAsciiStream(1, dataStream, -1); 似乎是正确的。

我使用的是 JDBC 14.10.00.18，您可以尝试从 Teradata 的 Developer Exchange 下载最新版本 14.10.00.26:http://downloads.teradata.com/download/connectivity/jdbc-driver

我认为这不会解决问题，但是...
