You can specify the maximum line size and have a maximum of 50 files open simultaneously. Directory location of file. This string is a directory object name and must be specified in upper case. 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 national character set mode 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 character set.
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 character set.
The file must be opened in national character set mode, and must be encoded in the UTF8 character set. The file must be open for reading mode r. This procedure reads a RAW string value from a file and adjusts the file pointer ahead by the number of bytes read.
Your application should allow for this by catching the exception in its processing loop. 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 character set. Reading CSV file and store every row in a string varible.
