CREATE DATABASENameCREATE DATABASE -- create a new database SynopsisCREATE DATABASE name
[ [ WITH ] [ OWNER [=] dbowner ]
[ TEMPLATE [=] template ]
[ ENCODING [=] encoding ]
[ TABLESPACE [=] tablespace ] ] Description CREATE DATABASE creates a new
EnterpriseDB database.
To create a database, you must be a superuser or have the special
CREATEDB privilege.
See CREATE USER.
Normally, the creator becomes the owner of the new database.
Superusers can create databases owned by other users using the
OWNER clause. They can even create databases owned by
users with no special privileges. Non-superusers with CREATEDB
privilege can only create databases owned by them.
By default, the new database will be created by cloning the standard
system database template1. A different template can be
specified by writing TEMPLATE
name. In particular,
by writing TEMPLATE template0, you can create a virgin
database containing only the standard objects predefined by your
version of EnterpriseDB. This is useful
if you wish to avoid copying
any installation-local objects that may have been added to
template1.
Parameters- name
The name of a database to create.
- dbowner
The name of the database user who will own the new database,
or DEFAULT to use the default (namely, the
user executing the command).
- template
The name of the template from which to create the new database,
or DEFAULT to use the default template
(template1).
- encoding
Character set encoding to use in the new database. Specify
a string constant (e.g., 'SQL_ASCII'),
or an integer encoding number, or DEFAULT
to use the default encoding. The character sets supported by the
EnterpriseDB server are described in
Section 34.2.1.
- tablespace
The name of the tablespace that will be associated with the
new database, or DEFAULT to use the
template database's tablespace. This
tablespace will be the default tablespace used for objects
created in this database. See
CREATE TABLESPACE
for more information.
Optional parameters can be written in any order, not only the order
illustrated above.
Notes CREATE DATABASE cannot be executed inside a transaction
block.
Errors along the line of "could not initialize database directory"
are most likely related to insufficient permissions on the data
directory, a full disk, or other file system problems.
Use DROP DATABASE to remove a database.
Although it is possible to copy a database other than template1
by specifying its name as the template, this is not (yet) intended as
a general-purpose "COPY DATABASE" facility.
We recommend that databases used as templates be treated as read-only.
See Section 32.3 for more information.
Note that the maximum length limit for database name is 63 characters.
Examples To create a new database:
CREATE DATABASE lusiadas;
To create a database sales owned by user salesapp
with a default tablespace of salesspace:
CREATE DATABASE sales OWNER salesapp TABLESPACE salesspace;
To create a database music which supports the ISO-8859-1
character set:
CREATE DATABASE music ENCODING 'LATIN1';
