CREATE DATABASE
creates a new database. To create a database, you must be a superuser or have the special CREATEDB
privilege.
The creator becomes the owner of the new database by default. Superusers can create databases owned by other users by 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 themselves.
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 clean database containing only the standard objects predefined by Greenplum Database. This is useful if you wish to avoid copying any installation-local objects that may have been added to template1
.
DEFAULT
to use the default owner (the user executing the command).
DEFAULT
to use the default template (template1).
'SQL_ASCII'
), an integer encoding number, or
DEFAULT
to use the default encoding. For more information, see
Character Set Support.
DEFAULT
to use the template database's tablespace. This tablespace will be the default tablespace used for objects created in this database.
CREATE DATABASE
cannot be executed inside a transaction block.
When you copy a database by specifying its name as the template, no other sessions can be connected to the template database while it is being copied. New connections to the template database are locked out until CREATE DATABASE
completes.
The CONNECTION LIMIT
is not enforced against superusers.
To create a new database:
CREATE DATABASE gpdb;
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';
There is no CREATE DATABASE
statement in the SQL standard. Databases are equivalent to catalogs, whose creation is implementation-defined.
