A valid table name in the geodatabase cannot start with a number; it must start with a letter.
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.
