prajakta said...this is very eassy to understand
John T said...That is so cool, just what I was looking for.
Thank you for sharing.
Motasem said...That is very impressive,
but the question is how can i write to file?
thank you very much
Oracle reads and writes files using th UTL_FILE package.
If you have any questions about UTL_FILE, please ask them on the forum.
thanks for replay,
i know how to use utl_file package,
but i need to use java classes to write to xml file.
all classes are worked with me but for the .txt files only
Hindy said...Is there any way to use these functions in the file_api package within an sql query?
Questions in the forum, not in the comments!
Open a forum thread and tell me the type of thing you want to do and we'll discuss it there.
Sander said...Thanks a million !!
I've been looking like crazy for a functionality in PL/SQL which simply lists the files in a directory. This is the only easy option I found !!
Thanks again !
Santosh said...This is really useful..!! Thanks a million Tim....
daih said...Hi, Tim:
I tried your code, but it didn't work on my side. My email is firstname.lastname@example.org. Would you please email me to help me out? Thanks.
Slavo said...I've been also looking for a functionality to list the files in a directory. And finnaly found !! :)
it is very helpful for me. But the following query not working some time.It throw ora-24345 error. Mostly the number of files high.
select file_api.list('Directory_path') from dual
For this, i used StringBuffer method instead of String. But still it throw error. i found the reason why it throw error. because of file_api.list function return varchar2 value. If i change that value varchar2 to clob then it will throw inconsistent data type error.
Please help for this.
please mail email@example.com
Claudio said...Hi All,
I have just one problem with this impressive solution.
In the list method, the variable returned is a string and it is fixed to 32767 bytes. My list of files is too big, do you know how can I solve this? Is there any way or workaround?
You would have to rewrite the list function to append the data into a CLOB type, rather than a string.
Emito said...excelent!!! tks!!!
Dan Ismael said...Hi Tim, i did the procedure without an error, but when i execute any sentense always appear 0 "canRead : 0
copy : 0
isFile : 0"
The files must be present and Oracle must have the correct OS permissions to read/write them. In addition, you must grant the JVM permission to access the file system.
If you have any more trouble, post it on my forum and I'll take a proper look at it.
Sreekanth said...Hi Tim,
Always output is coming 0.
How can i get output
Can u plz tel me
Open a thread on the forum and we'll discuss it. Chances are it is a permissions issue.
Andreas said...Really great work! Much appreciated.
Lauri said...A very good work. Compliments!!
Senthil said...With this I am able to read the files in the same server. If I want to read files which are present in a remove server, how can I do it?
Only sensible options for this are NFS or CIFS shares, so it looks like a local file to the database. :)
Alistair Wall said...There should be a security warning about using '>' instead of specific folders. For instance, it could be used to overwrite a password file.
Yes. Very old article. :) I've added a couple of warnings.
