java如何创建一个示例FastLoad1。csv文件看起来像什么？
我试着跟着这个example code
除了这条线，一切都很好
pstmtFld.setAsciiStream(1, dataStream, -1);
它抛出SQL异常
我怀疑我创建的样本FastLoad1.csv文件与他们的示例不一致。但是，我尝试创建一个非常简单的文件，其中包含完全相同的字段。这是我的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
它是正确的csv文件。它与示例程序一致吗？如果是，为什么会抛出异常
这是错误消息
Attempting connection to Teradata with FastLoadCSV.

# 1 楼答案
L_TIMESTAMP应该是一个时间戳，但它是CSV中的一个日期。而且格式可能不正确。执行“显示表格”并检查格式，然后相应地修改数据或将其添加到插入：
当你使用两位数的年份时，你可能得不到预期的世纪（基于一些dbscontrol设置）

是的，这是正确的csv文件。 但是，如果你想生成csv格式的虚拟数据， 这里有一个链接http://dummydata.me/ 可能对你有用
