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.
