FastLoad1.csv文件样本应该如何？

Question

我试着按照这个示例代码

除了这一行,一切正常

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

它抛出SQL异常.

我怀疑FastLoad1.csv我创建的示例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

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？

Answer 1

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.

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.做一个SHOW TABLE并检查FORMAT,然后相应地修改你的数据或将它添加到你的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)
