File system access restriction

For security reasons, Qlik Sense in standard mode does not support absolute or relative paths in the data load script or functions and variables that expose the file system.

However, since absolute and relative paths were supported in QlikView, it is possible to disable standard mode and use legacy mode in order to reuse QlikView load scripts.

Disabling standard mode can create a security risk by exposing the file system.

Security aspects when connecting to file based ODBC and OLE DB data connections

ODBC and OLE DB data connections using file-based drivers will expose the path to the connected data file in the connection string. The path can be exposed when the connection is edited, in the data selection dialog, or in certain SQL queries. This is the case both in standard mode and legacy mode.

If exposing the path to the data file is a concern, it is recommended to connect to the data file using a folder data connection if it is possible.

Limitations in standard mode

Several statements, variables and functions cannot be used or have limitations in standard mode. Using unsupported statements in the data load script produces an error when the load script runs. Error messages can be found in the script log file. Using unsupported variables and functions does not produce error messages or log file entries. Instead, the function returns NULL.

There is no indication that a variable, statement or function is unsupported when you are editing the data load script.

System variables

Variable	Standard mode / Qlik Sense Cloud	Legacy mode	Definition
Floppy	Not supported	Supported	Returns the drive letter of the first floppy drive found, normally a:.
CD	Not supported	Supported	Returns the drive letter of the first CD-ROM drive found. If no CD-ROM is found, then c: is returned.
QvPath	Not supported	Supported	Returns the browse string to the Qlik Sense executable.
QvRoot	Not supported	Supported	Returns the root directory of the Qlik Sense executable.
QvWorkPath	Not supported	Supported	Returns the browse string to the current Qlik Sense app.
QvWorkRoot	Not supported	Supported	Returns the root directory of the current Qlik Sense app.
WinPath	Not supported	Supported	Returns the browse string to Windows.
WinRoot	Not supported	Supported	Returns the root directory of Windows.
$(include=...)	Supported input: Library connection	Supported input: Library connection or absolute/relative path	The Include/Must_Include variable specifies a file that contains text that should be included in the script and evaluated as script code. You can store parts of your script code in a separate text file and reuse it in several apps. This is a user-defined variable.

Regular script statements

Statement	Standard mode / Qlik Sense Cloud	Legacy mode	Definition
Binary See: Binary	Supported input: Library connection	Supported input: Library connection or absolute/relative path	The binary statement is used for loading data from another app.
Connect See: Connect	Supported input: Library connection	Supported input: Library connection or absolute/relative path	The CONNECT statement is used to define Qlik Sense access to a general database through the OLE DB/ODBC interface. For ODBC, the data source first needs to be specified using the ODBC administrator.
Directory See: Directory	Supported input: Library connection	Supported input: Library connection or absolute/relative path	The Directory statement defines which directory to look in for data files in subsequent LOAD statements, until a new Directory statement is made.
Execute See: Execute	Not supported	Supported input: Library connection or absolute/relative path	The Execute statement is used to run other programs while Qlik Sense is loading data. For example, to make conversions that are necessary.
LOAD from ... See: Load	Supported input: Library connection	Supported input: Library connection or absolute/relative path	Returns the browse string to the Qlik Sense executable.
Store into ... See: Store	Supported input: Library connection	Supported input: Library connection or absolute/relative path	Returns the root directory of the Qlik Sense executable.

Script control statements

Statement	Standard mode / Qlik Sense Cloud	Legacy mode	Definition
For each... filelist mask/dirlist mask See: For each..next	Supported input: Library connection Returned output: Library connection	Supported input: Library connection or absolute/relative path Returned output: Library connection or absolute path, depending on input	The filelist mask syntax produces a comma separated list of all files in the current directory matching the filelist mask. The dirlist mask syntax produces a comma separated list of all directories in the current directory matching the directory name mask.

The filelist mask syntax produces a comma separated list of all files in the current directory matching the filelist mask. The dirlist mask syntax produces a comma separated list of all directories in the current directory matching the directory name mask.

File functions

Function	Standard mode / Qlik Sense Cloud	Legacy mode	Definition
Attribute() See: Attribute - script function	Supported input: Library connection	Supported input: Library connection or absolute/relative path	Returns the value of the meta tags of different media files as text.
ConnectString() See: ConnectString - script function	Returned output: Library connection name	Library connection name or actual connection, depending on input	Returns the active connect string for ODBC or OLE DB connections.
FileDir() See: FileDir - script function	Returned output: Library connection	Returned output: Library connection or absolute path, depending on input	The FileDir function returns a string containing the path to the directory of the table file currently being read.
FilePath() See: FilePath - script function	Returned output: Library connection	Returned output: Library connection or absolute path, depending on input	The FilePath function returns a string containing the full path to the table file currently being read.
FileSize() See: FileSize - script function	Supported input: Library connection	Supported input: Library connection or absolute/relative path	The FileSize function returns an integer containing the size in bytes of the file filename or, if no filename is specified, of the table file currently being read.
FileTime() See: FileTime - script function	Supported input: Library connection	Supported input: Library connection or absolute/relative path	The FileTime function returns a timestamp for the date and time of the last modification of the file filename. If no filename is specified, the function will refer to the currently read table file.
GetFolderPath() See: GetFolderPath - script function	Not supported	Returned output: Absolute path	The GetFolderPath function returns the value of the Microsoft Windows SHGetFolderPath function. This function takes as input the name of a Microsoft Windows folder and returns the full path of the folder.
QvdCreateTime() See: QvdCreateTime - script function	Supported input: Library connection	Supported input: Library connection or absolute/relative path	This script function returns the XML-header time stamp from a QVD file, if any is present, otherwise it returns NULL.
QvdFieldName() See: QvdFieldName - script function	Supported input: Library connection	Supported input: Library connection or absolute/relative path	This script function returns the name of field number fieldno, if it exists in a QVD file (otherwise NULL).
QvdNoOfFields() See: QvdNoOfFields - script function	Supported input: Library connection	Supported input: Library connection or absolute/relative path	This script function returns the number of fields in a QVD file.
QvdNoOfRecords() See: QvdNoOfRecords - script function	Supported input: Library connection	Supported input: Library connection or absolute/relative path	This script function returns the number of records currently in a QVD file.
