The output feature-class (table) of the Geocoding geoprocessing tool limits Field Name Lengths to 31 (32-1) characters. Most enterprise database management systems allow field names to be much longer than 31 characters.
An enhancement to this tool would be to allow the output of the Geocoding geoprocessing tool to match the field name length limitations of the output database (including such database systems as file-geodatabase, SQL Server, PostgreSQL, Oracle, etc.)
