Hi,
I have a table of file information. For image files, I wish to include a
width and height field. Since most of my files are not images these fields
will be null in about 95% of records.
Is it better to put this field in a new table and create a join between
the
two tables? Is having a field with a lot of null values wasteful? In
Access,
unlike SQL Server, there is no varchar data type.
I would appreciate any advice.
Regards
John
