Specifies the file associated with the database.
If you omit the FILENAME argument, the file specification takes
the following defaults:
o Device: the current device for the process
o Directory: the current directory for the process
o File name: the alias (if you omit the FILENAME argument, you
must specify the WITH ALIAS clause)
Use either a full file specification or a partial file
specification. You can use a logical name for all or part of a
file specification.
If you use a simple file name, SQL creates the database in the
current default directory. Because the IMPORT statement may
create more than one file with different file extensions, do
not specify a file extension with the file specification.
