  • 0

I am designing a relational database schema that may be ported to multiple database platforms–SQLite3, PostgreSQL and MySQL and possibly others.

I would like to create table names that would be portable across all the database platforms. What are naming restrictions should I follow?

  • What characters are allowed?
  • What characters are allowed to begin the name?
  • What is the maximum length?
  • Are there other restrictions I should be aware of?

Thanks

    /^[a-zA-Z][a-zA-Z0-9_]{,9}$/ is generally safe.
