About naming fields
Follow these guidelines when naming fields:
1 Field names must be unique. They can contain up to 100 characters.
1 Use descriptive names that clearly identify the contents of the field. Avoid
abbreviations, acronyms, or other terms that may cause confusion.
1 Don’t use any of the following symbols or words in the field name:
1 , (comma) + – * / ^ & = > < ≥ ≤ ( ) [ ] } " ; (semicolon) : (colon) ::
(relational indicator) $ (variable indicator)
1 AND, OR, XOR, NOT, or the name of any FileMaker Pro function
1 Don’t begin a field name to be used in a calculation formula with a space,
period (.), or number.
1 Use _ (underscore) in place of a space to avoid restrictions in ODBC (Open
Database Connectivity) or JDBC (Java Database Connectivity), exporting,
web publishing, and other operations.
1 If you’re exchanging data with another application, check the field naming
restrictions in the file formats supported by the other application.
1 If you’re using ODBC or JDBC to share FileMaker Pro data, avoid using
SQL keywords in field names.
