SQL/MX Statements
HP NonStop SQL/MX Reference Manual—540440-003

Syntax Description of CREATE TABLE
store-option is defined as:
PRIMARY KEY
bases the clustering key on the primary key columns. This store option
requires that the primary key is NOT DROPPABLE. If the primary key is
defined as DROPPABLE, NonStop SQL/MX returns an error.
key-column-list
bases the clustering key on the columns in the key-column-list. The key
columns in key-column-list must be specified as NOT NULL NOT
DROPPABLE and cannot have a combined length of more than 247 bytes.
The default is PRIMARY KEY if you specified a PRIMARY KEY clause that has the
NOT DROPPABLE constraint in the CREATE TABLE statement.
If you omit the STORE BY clause and you do not specify a PRIMARY KEY that
has the NOT DROPPABLE constraint, the storage order is determined only by the
SYSKEY. You cannot partition a table stored only by SYSKEY. See SYSKEYs on
page 6-59.
LOCATION [\node.]$volume[.subvolume.file-name]
[NAME partition-name]
specifies a physical location for the primary partition of the table.
node
is the name of a node on the Expand network.
For Guardian files representing a table or index partition or a view label, node
can be any node from which the object's catalog is visible.
volume
is the name of an audited, non-SMF DAM volume on the specified node (or the
Guardian volume named in the =_DEFAULTS define if none is specified).
If you do not specify a LOCATION clause and your system does not have a
value for the DDL_DEFAULT_LOCATIONS default (either in your environment
or at the system level) and your environment does not have a =_DEFAULTS
value, the CREATE statement will fail with an error.
subvolume
is the name of the schema subvolume for the schema in which the table is
being created.
Follow these guidelines when using SQL/MX subvolume names:
•
The name must begin with the letters ZSD, followed by a letter, not a digit
(for example, ZSDa, not ZSD2).
