我正在官方Teradata网站测试快速载荷示例代码。要在谨慎的一边犯错，我在其样品上使用示例FastLoad1.csv。
运行此示例代码时，我会在此行中获得错误
pstmtFld.setAsciiStream(1, dataStream, -1); // This method is not implemented
如何与准备的语句一起使用setAsciistram？
我是否正确使用setAsciiStream？
这是控制台中的错误消息

我试图编译示例T20208JD，刚刚修改了DNS/用户/密码，并且在我的Mac上运行顺利。因此， 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的开发人员Exchange下载最新版本14.10.00.26
我认为这不会解决问题，但是...
我认为错误是由第三个参数-1引起的，该参数告诉setaSciistream，bytestream具有 -1 bytes。
过去使用setAsciiStream()时，如果bufferInputStream的大小超过254个字符，则使用CC_6和大小。
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，将我的比较与您的比较，我可以告诉第三个参数是不同的，应该是输入流的length。
