1.5. Character Usage Restrictions

To review, database identifiers, field names, and product codes (database keys) are restricted in the characters they may use. The following table shows the restrictions:

                                  Legal characters
 Database identifiers             A-Z a-z 0-9 _
 Field names                      A-Z a-z 0-9 _
 Database keys (product code/SKU) A-Z a-z 0-9 _ # - . /
 Database values                  Any (subject to field/record delimiter)

Some SQL databases have reserved words which cannot be used as field names; Interchange databases do not have this restriction.

For easy HTML compatibility, it is not recommended that a / be used in a part number if using the flypage capability. It can still be called [page href=flypage arg="S/KU"].
