Rules for Naming Databases
Database names must follow these rules:
They must be unique within an installation.
They must begin with an alphabetic character (not the underscore).
No special characters other than the underscore, dollar sign, and at symbol (@) are allowed for regular identifiers.
The maximum length of a database name is 32 bytes. However, the name must be unique to 24 bytes (or the maximum file name length imposed by your operating system, if less than 24).
Case significance (upper or lower) is determined by the settings for the database in which the object is created (Ingres or ANSI/ISO Entry SQL-92-compliant) and may differ for delimited and non-delimited identifiers).
For details about identifier syntax, see the SQL Language Guide.
