utl file fopen – ORACLE

Rules and Limits. UTL_FILE I/O capabilities are similar to standard operating system stream file I/O ( OPEN, GET, PUT, CLOSE) capabilities, but with some limitations. For example, you call the FOPEN function to return a file handle, which you use in subsequent calls to GET_LINE or PUT to perform stream I/O to a file.

UTL_FILE FOPEN and FOPEN_NCHAR Functions. The FOPEN function opens the file in the database character set and returns the handle which can be then used for manipulating the file content. The FOPEN_NCHAR function opens the file in the national character set and manipulates it in UNICODE instead of the database character set.

Sep 25, 2007 · Then, to use the directory object in your call to UTL_FILE, ensure you specify the name of the directory object in quotes and in UPPER case. e.g. fh := UTL_FILE.FOPEN(‘MY_DIR’, ‘myfile.txt’, ‘w’); This also has the advantage that the location can be changed throughout all your code (assuming you access files from multiple places in your code) simply by altering the directory object.

UTL_FILE expects that files opened by UTL_FILE.FOPEN in text mode are encoded in the database character set. It expects that files opened by UTL_FILE.FOPEN_NCHAR in text mode are encoded in the UTF8 character set. If an opened file is not encoded in the expected character set, the result of an attempt to read the file is indeterminate.

UTL_FILE works for both server and client machine systems. A directory has to be created on the server, which points to the target file.

When using UTL_FILE you must specify the directories you will be using in the INIT.ORA file on the server. Some people will specify a wild card ‘*’ for the directory but it is not recommended because it can make your system vulnerable.

The file handle is defined by a public variable in the UTL_FILE package named, UTL_FILE.FILE_TYPE. A variable of type FILE_TYPE must be declared to receive the file handle returned by calling the FOPEN function. The file handle is then used for all subsequent operations on the file.
