Close all files. Copies a contiguous portion of a file to a newly created file. Physically writes pending data to the file identified by the file handle. Reads and returns the attributes of a disk file. Returns the current relative offset position within a file, in bytes. Open a file for read operations. Delete An Operating System File. Rename An Operating System File. Adjusts the file pointer forward or backward within the file by the number of bytes specified.
Read a Line from a file. Read a line from a file containing multi-byte characters. Reads a RAW string value from a file and adjusts the file pointer ahead by the number of bytes read.
Writes one or more operating system-specific line terminators to a file. Writes a string to a file. A PUT procedure with formatting. Writes a line to a file. File name, including extension file type , without directory path. Maximum number of characters for each line, including the newline character, for this file minimum value 1, maximum value FOPEN returns a file handle, which must be passed to all subsequent procedures that operate on that file.
This function opens a file in Unicode for input or output, with the maximum line size specified. You can have a maximum of 50 files open simultaneously. With this function, you can read or write a text file in Unicode instead of in the database charset.
Maximum number of characters for each line, including the newline character, for this file. An exception is returned on failure.
This procedure renames an existing file to a new name, similar to the UNIX mv function. Permission on both the source and destination directories must be granted. You can use the overwrite parameter to specify whether or not to overwrite a file if one exists in the destination directory. This procedure adjusts the file pointer forward or backward within the file by the number of bytes specified.
You must know the number of bytes by which you want to navigate. If the beginning of the file is reached before the number of bytes specified, then the file pointer is placed at the beginning of the file. This procedure reads text from the open file identified by the file handle and places the text in the output buffer parameter.
Text is read up to, but not including, the line terminator, or up to the end of the file, or up to the end of the len parameter. The number of bytes read from the file. Default is NULL. Because the line terminator character is not read into the buffer, reading blank lines returns empty strings. With this function, you can read a text file in Unicode instead of in the database charset. The file must be open for reading mode r. This function reads a RAW string value from a file and adjusts the file pointer ahead by the number of bytes read.
This function tests a file handle to see if it identifies an open file. It does not guarantee that there will be no operating system errors when you attempt to use the file handle.
This procedure writes one or more line terminators to the file identified by the input file handle. This procedure is separate from PUT because the line terminator is a platform-specific character or sequence of characters. PUT writes the text string stored in the buffer parameter to the open file identified by the file handle. The file must be open for write operations. The file must be open for writing. The sum of all sequential PUT calls cannot exceed without intermediate buffer flushes.
This procedure writes the text string stored in the buffer parameter to the open file identified by the file handle. With this function, you can write a text file in Unicode instead of in the database charset. See also "PUT Procedure". This procedure is a formatted PUT procedure. It works like a limited printf. Java is a non-trivial language, it is huge. PLSQL is small, simple, yet surprisingly complete hey, if they could write advanced replication in Oracle 7.
There is room for more then one language in the world. I use that until I cannot do it with that language or it is too awkward -- then I use java. When I cannot do it in Java -- I do it in C hey, if C is a replacement for Java when Java cannot do it or cannot do it efficiently -- maybe we should all write in C -- or assembler?
PLSQL is here to stay, don't worry about that. No, I do not forsee the plsql statement packages being rewritten in Java most of them are written mostly in C today actually and are just wrappers and I should have mentioned You can add directories on the fly.
Thank you, you answer was very useful! By the way, I read your entire book already! Very good one, indeed! Thank you! Hi Tom ClobUtil is not doing any database activity, so why is an Oracle connection opened? January 15, - am UTC. January 21, - pm UTC. You could put it into your OWN table and fetch it out Use your own table.
Thanks Brijesh. January 22, - am UTC. Your shared pool is pretty small -- and your java pool size is far too small to run anything java. Is this effective immediately? June 09, - pm UTC. That's cool And the other way? Steve, June 16, - am UTC.
I have to save files to numerous directories. Is there a similar technique available rather than have to declare 55 directories? Cheers Steve. June 16, - am UTC. My mistake! I meant to say read in files from 55 directories, but presumably your answer still applies! No, but if HR created it, HR can write it. It also allows deletion. Then that user can write. June 19, - pm UTC. I am trying to create directories with of shared drives on my client.
I am using Oracle 9i R2 on wind I have mapped drives e. August 09, - pm UTC. When you log in -- those shared drives exist -- but when you friend down the hall logs in -- what is g: or h:? What you see is what YOU see, Oracle cannot see it. In oracle 9i I suppose one can use directory to write to csv file All I want to do is to write to csv file from a table.. I have init.
