That is very impressive,
but the question is how can i write to file?

thank you very much

Hi.

Oracle reads and writes files using th UTL_FILE package.

If you have any questions about UTL_FILE, please ask them on the forum.

Cheers

hi,
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?

Tim... said...

Hi.

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.

Cheers

Hi
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 dharmaarvin@gmail.com

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?

Tim... said...

Hi.

You would have to rewrite the list function to append the data into a CLOB type, rather than a string.

Cheers

Hi Tim, i did the procedure without an error, but when i execute any sentense always appear 0 "canRead : 0
copy : 0
isFile : 0"

Tim... said...

Hi.

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.

Cheers

Tim... said...

Hi.

Open a thread on the forum and we'll discuss it. Chances are it is a permissions issue.

Cheers
