示例FastLoad1.csv文件應該如何顯示？

Question

我試圖按照這種example code

一切工作正常，除了這行

   pstmtFld.setAsciiStream(1, dataStream, -1); 

它拋出SQL異常。

我懷疑我創建的示例FastLoad1.csv文件與他們的示例不一致。不過，我試圖創建一個非常簡單的文件與完全相同的領域。這是我的FastLoad1.csv

L_INDEX,L_TIMESTAMP,L_TEXT 
1,01/01/13,testText 
2,01/01/13,testText 
3,01/01/13,testText 
4,01/01/13,testText 

它是正確的csv文件。它與示例程序是否一致？如果是，爲什麼會拋出異常？

Answer 1

L_TIMESTAMP應該是一個時間戳，但它是CSV中的一個日期。它可能不是正確的格式。做一個節目表和檢查格式，然後相應地修改您的數據或將其添加到您的INSERT：

VALUES(?,? (TIMESTAMP, FORMAT 'mm/dd/yy'),?) 

而當你使用一個兩位數的年份，你可能無法得到預期的世紀（基於一些dbscontrol設置）

Answer 2

是的，這是正確的CSV文件。 但是，如果你想生成csv格式的虛擬數據， 這裏是一個鏈接http://dummydata.me/ 可能對你有用。
