.txt or CSV file to Database

Hi-
I have a text file generated by a Pulse Oximeter, What I want is, as the system recieves the file (in .txt of CSV) it automaticly is entered into a MySql Database or SQL Server and generates an SMS message. Thanks
Regards

Web services imply using sychronous communication. However, the use case you describe implies that asynchronous, so-called fire-and-forget, communication is better suited to your needs.
For example, with sychronous communication, the system is unaware of the exact moment a TXT or CSV file will come in. Also, when the system is processing a file, all other processing waits until the system finishes. This may cause synchronicity problems if multiple files come into the system in quick succession.
ColdFusion has an asynchronous solution that suits every requirement of your use case. The following methods will enable you to receive the file, to automatically enter it into the database and to generate an SMS message. Use ColdFusion's DirectoryWatcher gateway to monitor the directory in which the TXT or CSV files are dropped, and ColdFusion's SMS event gateway to send SMS messages.
Whenever a third party drops a file into the directory, an event is triggered, setting the DirectoryWatcher into action. Implement a query in the onAdd method of the DirectoryWatcher's listener CFC to store the file in the database. Following the query, use the sendGatewayMessage method to send the SMS message.

I take it your are trying to use a csv file to insert new data into a database, using flex and coldfusion?
if so, then I would load the file in flex using cffile in ColdFusion and then use Load Data if you are using MySQL
This can show you more about it.

We get very large csv files ftp'd to us every week, and we have to load them in to the db. this works for us.

Insert Data into Table from TXT or CSV file !!!!!

Dear All,
Recently I have started working on APEX. In Oracle Forms, we used to use TEXT_IO for inserting records into tables from txt files. Now I want to do the same thing in apex 3.2. How can I insert data into tables from txt of csv files.
Waiting of your valuable suggestions.
With kind regards,
Yousuf.

Yousuf
wwv_flow_files is used by APEX to hold uploaded files.
If you incorporate a file browse item on you page, browse for the selected file, then submit the page (having the PL/SQL process described as an on suibmit process) then what I detailed should work.
If you don't need users to have access to this then just go to Home>Utilities>Data Load/Unload in APEX and there is a handy load utility there that does it all for you.
Cheers

Renaming files using a list of names in a txt or csv file

Hello everyone,
I'm trying to use AppleScript (although I'm a total noob to it) to rename the files in a folder (if possible using something like this - set folder to choose folder) to coincide to a list of names (in a txt or csv - can be any extension needed).
To paint the picture clearer I'll have something like this
Files_as_they_are
Files_renamed
01.mkv
Valar Dohaeris.mkv
02.mkv
Mhysa.mkv
Here is what I've tryed so far : (some point through the night I've tryed to repeat part of the process thus the "fcount" but the result was even worse)
set theFolder to choose folder
set ep to {"Valar Dohaeris", "Dark Wings, Dark Words"}
set fcount to 1
tell application "Finder"
set name of file fcount of theFolder to item fcount of ep
end tell
set fcount to fcount + 1
Tnx in advance...

This will work with a comma separated text file,
i.e.:
     Files as the are, Files Renamed
     01.mkv, Valar Dohaeris.mkv
     02.mkv, Mhysa.mkv
Note that if the file to be renamed exists, it will be overwritten (A test can be added to skip if exists if needed)
set theFoler to POSIX path of (choose folder with prompt "Choose folder with Files" default location path to desktop)
set theFile to POSIX path of (choose file with prompt "Choose TXT file" default location path to desktop)
do shell script "
cd " & quoted form of theFoler & "
while read line
do
     OldImageName=${line%,*}
     NewImageName=${line#*,}
     if [ -e \"$OldImageName\" ] ; then
          mv \"$OldImageName\" \"$NewImageName\"
     else
          echo \"$OldImageName\" >> ~/Desktop/Errors.txt
     fi
done < " & quoted form of theFile & "

Sending csv files to database

Hi,any suggestions welcome.I have a page that gets a .CSV file for user names from the local system and sends it a servlet to parse and send to the database.I inetnd to use a servlet to parse the csv files and insert into the database.Is there any easier method of implementation,or can i use that method.
Thanks in advance

Databases usually have utilities which read CSV and upload data into the database. These are faster than JDBC, but that would mean using Runtime.exec(). I guess you will have to go for parsing the files and inserting the records in batches.

How to save a .csv file to database server

Hi every body,
I need to upload a .csv file from the client machine and save it to a directory in a database sever.
I could do the uploading part. Can anyone tell me how to save the file?
Another option is save the file as a CLOB in a database column. But I'm not aware of doing that too.
Please guide me.
Thanks in advance.
Surangi.

See Steve Muench's Not Yet Documented Example #85 at http://radio.weblogs.com/0118231/stories/2004/09/23/notYetDocumentedAdfSampleApplications.html#85. While this is for 10.1.3, this is still relevant for 11g. Steve's example is for uploading to a BLOB - same thing for a CLOB. Once your data is in the database, you can use the DBMS_LOB package to write the file to a directory on the database server, if you like.
Also the Developers Guide is your friend - Chapter 9.9 in the Fusion Web User Interface Developers Guide for Oracle ADF 11g, or 19.6 in the ADF Developers Guide for Forms/4GL Developers for JDeveloper 10.1.3.

CSV FILE TO DATABASE

m neame coloumns awsto java. i have a requirement.i hav a csv file .i have database table which has same coloumns as the csv field names.
i have to upload the contents of the csv file in to the table.
at present i am being able to read each line in da csv file using the readLine method and storing into array.
i have to now insert this row into the database using prepared statement.
but how do i set the values into the preared statement.
i am retrieving each row from the csv.
can anyone help me

Try http://www.aquafold.com/ Aqua Data.
It loads data from formats such as CSV and loads them
into an existing table.
Plus many other cool features.Peter, thanks for that link. Looks neat.
To the OP:
You have at least two options:
1. Use Java to load the data through a series of INSERT statements.
2. Use the bulk loader facilities found in many of todays RDBMS.
Now go do your homework.

How to read the CSV Files into Database Table

Hi
Friends i have a Table called tblstudent this has the following fields Student ID, StudentName ,Class,Father_Name, Mother_Name.
Now i have a CSV File with 1500 records with all These Fields. Now in my Program there is a need for me to read all these Records into this Table tblstudent.
Note: I have got already 2000 records in the Table tblstudent now i would like to read all these CSV File records into the Table tblstudent.
Please give me some examples to do this
Thank your for your service
Cheers
Jofin

1) Read the CSV file line by line using BufferedReader.
2) Convert each line (record) to a List and add it to a parent List. If you know the columns before, you might use a List of DTO's.
3) Finally save the two-dimensional List or the List of DTO's into the datatable using plain JDBC or any kind of ORM (Hibernate and so on).
This article contains some useful code snippets to parse a CSV: http://balusc.xs4all.nl/srv/dev-jep-csv.html

How to regularly load data from .csv file to database (using apex)

Hi,
i am using apex3 , I need to load data from a csv file to apex . I need to perform this automatically through code at regular time interval of 5-10 seconds.
Is it possible .If yes how ?. Please reply as early as possible. This will decide whether to use apex or not for this application.
this is question for Application Express. Dont know why in forum for BPEL
Edited by: TEJU on Oct 24, 2008 2:57 PM

Hello,
You really need to load the data every 5-10 seconds? Presumably it's read only?
I would look at using an Oracle external table instead, that way you just drop your CSV in a location the DB can read it and then you build a table that essentially references the underlying CSV (that way when you query the table you view the data in the CSV file).
Take a look at this link for a quick example on usage -
http://www.oracle-base.com/articles/9i/SQLNewFeatures9i.php#ExternalTables
Hope this helps,
John.
