000447: Name must not start with a number.
Description
A valid table name in the geodatabase cannot start with a number; it must start with a letter.
Solution
Follow proper table naming conventions:
Names must begin with a letter, not a number or special character such as an asterisk (*) or percent sign (%).
Names should not contain spaces. If you have a two-part name for a table or feature class, connect the words with an underscore (_), for example, garbage_routes.
Names should not contain reserved words, such as select or add. Consult your DBMS documentation for additional reserved words.
Names are limited to 32 characters. The database and schema names do not count toward the 32 characters.
