Hi,
It may be best to avoid numbers as identifiers, see the MySQL reference manual at
It says: "It is recommended that you do not use names of the form Me or MeN, where M and N are integers. For example, avoid using 1e or 2e2 as identifiers, because an expression such as 1e+3 is ambiguous. Depending on context, it might be interpreted as the expression 1e + 3 or as the number 1e+3."
