示例 FastLoad1.csv 文件应该是什么样子？

Question

我试着关注这个example code

除了这一行，一切正常

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

它抛出 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，我尝试创建一个具有完全相同字段的非常简单的文件。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。是否与示例程序一致？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， 这是一个链接http://dummydata.me/ 可能对你有用。

Answer 2

L_TIMESTAMP 应该是时间戳，但它是 CSV 中的日期。而且它可能不是正确的格式。做一个 SHOW TABLE 并检查 FORMAT，然后相应地修改您的数据或将其添加到您的 INSERT：

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

当您使用两位数年份时，您可能无法获得预期的世纪（基于某些 dbscontrol 设置）
