Utl file which user

With this function, you can read or write a text file in Unicode instead of in the database character set. This procedure does not verify privileges before deleting a file.

The operating system verifies file and directory permissions. This procedure adjusts the file pointer forward or backward within the file by the number of bytes specified. Use a positive integer to seek forward, a negative integer to see backward, or 0 for the current position. Default is NULL. 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. 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 character set. The file must be opened in national character set mode, and must be encoded in the UTF-8 character set. This procedure reads a RAW string value from a file and adjusts the file pointer ahead by the number of bytes read. It ignores line terminators. This function tests a file handle to see if it identifies an open file. It reports only whether a file handle represents a file that has been opened, but not yet closed.

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. There are some cases where it can be used to access files on network drives, but these tend to be specific, limited use case scenarios and don't necessarily work for most applications.

Add a comment. Active Oldest Votes. Two objections so far: when you create a directory an Oracle object , nothing is "automatically" created in filesystem. Note that directory usually resides on a database server. If you can't access the database server because of lack of privileges , you'll have to talk to DBA to do it for you.

Though, saying that you connected as sysdba , I presume that it shouldn't be a problem for you. Improve this answer.
