SQL99 Syntax and Description
CREATE SCHEMA [schema_name] [AUTHORIZATION owner_name] [DEFAULT CHARACTER SET char_set_name] [PATH schema_name [,...n] ] [ <create_table_statement1> [...n] ] [ <create_view_statement1> [...n] ] [ <grant statement1> [...n] ]
The CREATE SCHEMA
statement is a container that
can hold many other CREATE
and
GRANT
statements. As an option, a
DEFAULT CHARACTER SET
names the schema’s
default character set. The PATH
also may be
declared for any objects in the schema that reside on the filesystem.
Microsoft SQL Server and Oracle Syntax
CREATE SCHEMA AUTHORIZATION owner_name [ <create_table_statement1> [...n] ] [ <create_view_statement1> [...n] ] [ <grant statement1> [...n] ]
If any statement fails within the CREATE SCHEMA
statement, then the entire statement fails. One good thing about
CREATE SCHEMA
is that the objects within do not
need to be organized according to any dependency. For example, a
GRANT
statement normally could not be issued for
a table that does not exist yet. However, all the
GRANT
statements first could be placed in the
CREATE SCHEMA
statement, followed by the
CREATE
statements ...
