如何ascii流綁定到一個事先準備好的聲明

Question

我從official teradata website測試fastload示例代碼。過於謹慎的一面，我使用位於其samples.jar here

當我運行此示例代碼，我在這條線得到一個錯誤的樣本FastLoad1.csv

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

必須如何調用setAsciiStream可與使用準備好聲明？

難道我正確地使用setAsciiStream？

Answer 1

我試圖編譯示例T20208JD，剛剛修改DNS /用戶/密碼，它在我的Mac平穩運行。所以pstmtFld.setAsciiStream（1，dataStream，-1）;似乎是正確的。

我用JDBC 14.10.00.18，你可以嘗試從Teradata的開發者交流下載最新版本14.10.00.26：http://downloads.teradata.com/download/connectivity/jdbc-driver

我不認爲這將解決這個問題，但是......

Answer 2

錯誤消息，我認爲錯誤是由-1，第三個參數，它告訴調用setAsciiStream的字節流具有-1字節造成的。

當我在過去使用setAsciiStream()時，如果超過254個字符，我使用了bufferInputStream和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，比較雷到你，我可以告訴第三個參數是不同的應該是輸入流的length。
