File Functions in Script
The file functions (only available in script expressions) return information about the table file which is currently
being read. These functions will return NULL for all data sources except table files (Exception: ConnectString(
)).
Click on the functions that you would like to know more about:
Attribute(filename, attributename)
Returns the value of the meta tags of different file formats, e.g. MP3, WMA, WMV and JPG files, as text.
Example:
Filename is the name of a media file including path, if needed.
Attributename is the name of a meta tag.
If the file filename does not exist, is not a supported file format or does not contain a meta tag named
attributename, null will be returned.
A large number of meta tags can be used, e.g. ‘Artist’ or ‘Date Picture Taken’. The supported tags can
automatically be generated in the script. The keyboard shortcut for this generation is CTRL + Q,J,P,G
for jpg files (keep the CTRL key pressed while typing the QJPG combination), CTRL + Q,M,P,3 for
mp3 files and CTRL + Q,W,M,A for wma files.
Attribute('File', 'Title') as X,
returns the mp3 tag 'title' in field X in each record.
ConnectString()
Returns the active connect string for ODBC or OLE DB connection. Returns an empty string if no connect
statement has been executed or after a disconnect statement.
filebasename()
Returns a string containing the name of the table file currently being read, without path or extension.
Example:
Load *, filebasename( ) as X from
C:\UserFiles\abc.txt
Will return 'abc' in field X in each record read.
filedir()
Returns a string containing the path to the directory of the table file currently being read.
Example:
Load *, filedir( ) as X from
C:\UserFiles\abc.txt
Will return 'C:\UserFiles' in field X in each record read.
