iQuery.ifsDir - UDTF Published by: Bob Cozzi on 17 Jun 2019 view comments

List IFS Directory Entries and Attributes

The iQuery.ifsDir() UDTF returns a one row result that contains the attributes for the specified IFS file. The information returned in similar to that which is returned by the stat64() C runtime function.

Parameters

table( iQuery.ifsDir( 'fully-qualified IFS directory', optional-recursion flag ) )

The Fully-Qualified IFS Directory name is the name of the IFS directory, such as '/home' whose entries are to be returned.

The Optional Recursion Flag causes the UDTF to drill down into each subdirectory and include the entries for those subdirectories in the resultSet.

Result Set Columns

Column Type Description
ENTNAME varchar(640) The name of the IFS directory's Entry. Typically the file name or the subdirectory name.
ENTTYPE varchar(10) The entry type. Either STMF or DIR (note the leading asterisk is NOT returned by this UDTF)
ENTSIZE BIGINT The number of bytes the file occupies on disk. (the file size)
CRTDTS timeStamp The date/time when the entry was created.
ACCDTS timeStamp The date/time when the entry was last accessed.
CHGDTS timeStamp The date/time the entry's attributes where last changed.
MODDTS timeStamp The date/time the data in the file was last modified.
ENTEXT varchar(10) File Extension. For example, if the file name is SALES.PDF, this column contains: PDF
ENTNAMELEN smallint The length of the data in the ENTNAME column.
ENTFULLNAMELEN smallint The length of the fully qualified full name ENTFULLNAME column value.
ENTFULLNAME varchar(2048) The fully qualified entry name (first 2048 characters).

Example

select entType,entSize,crtdts,entName from table( iQuery.ifsDir( '/home/iquery') ) dir;

The output from the above UDTF would be similar to the following:
