When I upload a *.cvs file into Oracle Express using the data upload tool, the column mapping changes. I have uploaded the same data before, to test things out.
I then deleted all the data in the table and now want to load in fresh data for further testing. The mapping looks good in the *.cvs file before I upload it but when I get to the last step the columns have changed position in the *.cvs file.
Any idea why does this happen and what can I do to prevent it?

I am new on Minio and object based databases.
I know that there is S3 select API but I want to add a new row or update a specific row in CSV file in Minio without need to download it and upload again.
Is there any way to do it?
In another words, I want to use sql based statements(insert/update) on a file stored in Minio.
You can only change Databases with SQL, it can only Import and Export CSVs so that they are usable for the Database. The Answer for now would then be a no. The easiest way you could achieve editing this csv would be to write a Script which either:
Connects to the Database and Changes the File in the Databases
Directory.
Downloads the File to edit it locally and then upload it again.
I have an Oracle database that I am migrating data to a new server.
Everything is working perfectly, except that for some reason doing an exp uses data from the last time I ran it?
I have checked the timestamps of the dmp files and I am definitely using the new files to imp.
Anyone have any ideas?
I'm useing java to write some programe,
I need to insert some file into database such as ".mp3, .wav" files.
by the way how insert these file into oracle database?
Have you considered just storing the MP3 metadata and file location. I worked on a image server years ago and we attempted storing the images inside the database. It was much faster to just hand off the file location to the server service requesting it, then it would fetch the file. It is possible to load the mp3 binary file into a the database as a BLOB if you really want to.
I'm trying to load a table from SQL Server using the Microsoft OLE DB Provider into an Oracle table (using the Oracle Provider for OLE DB). The package is a straight forward OLE DB Source (SQL Server) -> OLE DB Destination (Oracle).
I'm using SQL Server 2008 R2 and Oracle 11g.
Every time I run the package, I get a different number of rows in the destination table, and BIDS reports fewer rows read than there are in the source table. The number of rows returned is different each time I run it. I get no errors or kickouts, but the boxes for the source and destination remain yellow even after BIDS says "Package completed successfully".
Dumping the source table into a flat file instead of the Oracle destination works fine, and I get all the rows that I expect. I can use this flat file to pull the information into the Oracle destination table without problems as well.
Even though I have a work-around, I want to understand why this is happening, and what I can do to resolve this problem without having to use flat files.
Edit: Looks like even using the flat file to Oracle doesn't bring over all the rows. The first time was just luck?
Edit/Update: Running the package out of Integration Services (not BIDS) seems to have eliminated the problem (tested three times). Still don't understand why this is happening though.
I have a SQLite table that I'm using for my iPad app. It currently has about 500 items, but I need to add about 200+ more. The thing is, the app is already deployed and has users, and it's an editable database in the documents directory, so it's not like I can just overwrite it. How can I add these new rows easily without destroying the table that I already have? It would be nice to import a txt somehow without having to do this manually. (For the record I am not using Core Data.)
Throwing out some ideas:
Can you not deploy a new database file in your update, and programatically detect if there is an existing db. If so, add the new data to the database and if not create a new db programatically, and add all your data to it.
You could store the setup data in an xml file perhaps?
ALTERNATELY, could your update have a second database? You don't overwrite your original db and you add a v1.1 db file? You could then merge the v1.1 data into the original db?
