GetCurrentFileName

GetCurrentFileName

For a data map record defined for a nonrelational data source, gets the name of the source data file.
Use the GetCurrentFileName function to determine the data file from which data for a record is read. You might use this information to complete the following tasks:
  • For a data map that is associated with a single data file, verify that all records from the data file were processed.
  • For a data map that is associated with a file-list file, verify that all records from all data files listed in the file-list file were processed.
  • Trace a row back to its original data file.
This function runs on all operating systems and runs in read mode. 
result
=GetCurrentFileName()
The following table describes the parameters:
Result
Description
Datatype
result
Returns the name of the the data file from which data for a record is read.
If the data map is associated with a file-list file, records might be read from multiple data files.
VARCHAR. Maximum length is 512 bytes plus a null termination character.
  • On i5/OS, the GetCurrentFileName function does not attempt to return the actual member name when a file is comprised of multiple members and *FIRST and *LAST are specified in the file name. The GetCurrentFileName function returns the file name that was passed to the open function.
  • On Linux, UNIX, and Windows, the GetCurrentFileName function does not attempt to get the full file name if it is qualified by relative directory paths, such as:
    ../../myfile.dat
    . Instead, the GetCurrentFileName function returns the following value:
    ../../myfile.dat
    .
  • In the following situations on z/OS, the GetCurrentFileName function might return file names that are more precise than the names listed in a file-list file:
    • Generation data group (GDG) file name in a data map or file-list file
    • DD name in a data map or file-list file
