如何将ascii流绑定到预准备语句
我正在测试官方teradata网站上的 fastload示例代码。 为了谨慎起见，我使用样本上的FastLoad1.csv样本FastLoad1.csv在这里
当我运行此示例代码时，我在此行中收到错误
pstmtFld.setAsciiStream(1, dataStream, -1); // This method is not implemented
setAsciiStream如何与预准备语句一起使用？
我正确使用setAsciiStream吗？
这是控制台中的错误消息

我试图编译示例T20208JD，只修改了DNS /用户/密码，它在我的Mac上运行顺畅。 所以pstmtFld.setAsciiStream（1，dataStream，-1）; 似乎是正确的。
我使用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……
我认为错误是由-1引起的，第三个参数告诉setAsciiStream byteStream有-1个字节。
当我以前使用过setAsciiStream()时，我使用了一个bufferInputStream ，如果超过254个字符，则使用String的大小。
String convRule; ... if (convRule.length() > 254) { int size = convRule.length(); BufferedInputStream bais = new BufferedInputStream( new ByteArrayInputStream( convRule.getBytes() ) ); pStmt.setAsciiStream( 4, bais, size ); }
所以，比较我和你的，我可以告诉第三个参数是不同的，应该是输入流的length 。
