CREATE DBSPACE statement


Description 

Use this statement to define a new database space and create the associated database file.

Syntax 

CREATE DBSPACE dbspace-name AS filename

Parameters 

dbspace-name    An internal name for the database file. The filename parameter is the actual name of the database file, with a path where necessary.

filename    A filename without an explicit directory is created in the same directory as the main database file. Any relative directory is relative to the main database file. The filename is relative to the database server. When you are using the database server for NetWare, the filename should use a volume name (not a drive letter) when an absolute directory is specified.

Usage 

The CREATE DBSPACE statement creates a new database file. When a database is created, it is composed of one file. All tables and indexes created are placed in that file. CREATE DBSPACE adds a new file to the database. This file can be on a different disk drive than the main file, which means that the database can be larger than one physical device.

For each database, there is a limit of twelve dbspaces in addition to the main file.

Each table is contained entirely within one database file. The IN clause of the CREATE TABLE statement specifies the dbspace into which a table is placed. Tables are put into the main database file by default.

Permissions 

Must have DBA authority.

Side effects 

Automatic commit. Automatic checkpoint.

  isbn char(30),
