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 is a formatted PUT procedure.
It works like a limited printf. Substitute this sequence with the string value of the next argument in the argument list. 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 function accepts as input a RAW data value and writes the value to the output buffer. You can request an automatic flush of the buffer by setting the third argument to TRUE.
Caution: The privileges needed to access files in a directory object are operating system specific. Attempting to apply invalid options will give rise to unpredictable results. Book List. Master Index. File could not be opened or operated on as requested. Operating system error occurred during the read operation. Operating system error occurred during the write operation. The requested operation failed because the file is open.

Copies a contiguous portion of a file to a newly created file. Physically writes all pending output to a file. Reads and returns the attributes of a disk file. Returns the current relative offset position within a file, in bytes. Opens a file in Unicode for input or output. Deletes a disk file, assuming that you have sufficient privileges. Renames an existing file to a new name, similar to the UNIX mv function.
Determines if a file handle refers to an open file. Writes one or more operating system-specific line terminators to a file. PUT Procedure. Compiling this procedure and executing it….
The ability to write files out like this must be safeguarded. Imagine the damage a malicious - or not - user can wreak by being able to what amounts to download from the database any document.
So just as potentially dangerous as writing files out to the file system, misuse of these two procedures, inadvertent or otherwise, can be disastrous. Imagine someone playing "what if" with database files. This package was introduced in the Oracle version 7. The different objects available in this package are described below.
This became a security threat as the directories present inside this parameter are accessible by any other database user.
Either read or write access to the directories created using this syntax can be granted to individual users or roles. The prototype for creating a directory is shown below,. The prototype for granting access to the directories to the database users is shown below,.
It does not guarantee you can use the file without error. This procedure writes one or more line terminators to the file identified by the input file handle. This procedure is distinct 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. No line terminator is appended by PUT. Table PUT procedure parameters. 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 character set. The file must be opened in the national character set mode.
The text string is written in the UTF-8 character set. This procedure accepts as input a RAW data value and writes the value to the output buffer. You can request an automatic flush of the buffer by setting autoflush to TRUE. This procedure is a formatted PUT procedure. It works like a limited printf. Table PUTF procedure parameters. Formatted text is written in the UTF-8 character set to the file identified by the file handle.
Either offset caused a seek past the end of the file. Attempts to clone file handles or use dummy file handles may have indeterminate outcomes.
FSEEK procedure Adjusts the file pointer forward or backward within the file by the number of bytes specified. PUT procedure Writes a string to a file. Permission to access to the file location is denied. Requested file delete operation failed. Requested operation failed because the file is open. The filename parameter is invalid.
File could not be opened or operated on as requested. Operating system error occurred during the read operation. Requested file rename operation failed. Operating system error occurred during the write operation. Indicates the internal file handle number numeric value. Indicates whether the file was open as a binary file or as a text file.
FCOPY procedure. Copies a contiguous portion of a file to a newly created file. Physically writes all pending output to a file. Reads and returns the attributes of a disk file. Returns the current relative offset position in bytes within a file, in bytes. FOPEN function. Opens a file in Unicode for input or output.
