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"].
