Question

进行操作

除了这一行

之外，一切正常

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

抛出SQL异常。

我怀疑我创建的示例FastLoad1.csv文件与他们的示例不一致。但是我试图用完全相同的字段创建一个非常简单的文件。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

csv文件是否正确。它与示例程序一致吗？如果是，为什么会抛出异常？

以下是错误消息

Answer 1

是的，这是正确的csv文件。但是，如果要生成csv格式的伪数据，这是一个链接http://dummydata.me/ 可能对你有用。

Answer 2

L_TIMESTAMP应该是一个时间戳，但它是CSV中的日期。它可能不是正确的格式。执行SHOW TABLE并检查FORMAT，然后相应地修改数据或将其添加到INSERT：

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

当你使用两位数的年份时，你可能无法获得预期的世纪（基于一些dbscontrol设置）

FastLoad1.csv文件样本应该如何？
