发帖数: 1530 | 2 如果你从来没用过数据库,那最简单的办法就是用script把文本框收集的数据写到一个
文本文件,格式用comma delimited CVS, 用MS office EXCEL 就可以打开这个CVS.
script 可以是ASP,PHP... 光是HTML是不够的.
当然最好是用数据库. ASP and ACCESS together should be enough for your case. |

程序在这里：

I issue a query (such as select A, B, from table C), and redirect the
results to a file. But I want to contact the format, such as whether to use
"|" as default delimiter to columns, or use "-" in the output header and
tails.
Thanks. |

发帖数: 1536 | 12 what is the source data format (before loading into Excel)?
Anyway, one way is:
1. export to txt format
2. re-import into excel, with the "|" as delimiter, so each number will take
one cell
BTW, this doesn't seem to be related to database... |

how to batch import text file such as csv or tab-delimited to
an oracle database?
which tools to use?
thank you? |
|
j*****n
发帖数: 1781 | 15 Here is a dummy solution....
use SSIS to export Oracle data into a text file (Delimited);
use SSIS to import this text file into your destination table. Better
predefine your destination table first, otherwise the data type may differ
when you create it while you import.
Another solution is that use data conversion component, which could do some
type transformations but is limited.
Sure, changing collations is always a pain in the S.
Let me know which one worked well for you. |

发帖数: 34098 | 40 we have ETL not informatica. My requirement is not typical.
For ETL you have to know the source format before creating a map.
For exp, if client send delimited file with 7 fields, then we create a map
to match this 7 fields to target. If client want send 8 fields or to wants
to send Fixed length file, we have to change the map. Now we want to have a
universal map can handle any format source based one the format information
in database. |

发帖数: 1879 | 41 最简单的办法我已经说了，你只要弄几个 class，对应 runlength scanning,
delimit scanning 等（这两个你该会吧，不会就没辙了）。然后就用 Spring
的 xml 做 record format 弄一 container，里面就是这几个 class object
和具体的 setting （比如 runlength 的长度等）。这样当用户给你个 xml，
你通过 Spring 读进该 xml，得到的是一个 list 的 scan action 。然后你
loop 这个 list 里的 action 不停的 parse record 就行了。
其它通过 Xml schema 设计的道理一样。自己 parse xml 说实在也很容易。 |

it converted "Jan-09" to Jan 09, 2008. Actually, it should be Jan-2009.
