Modules

This section describes the DDL commands pertaining to modules.

CREATE MODULE

Create a new module.

CREATE MODULE name [ IF NOT EXISTS ];

There’s a corresponding SDL declaration for a module, although in SDL a module declaration is likely to also include that module’s content.

Description

CREATE MODULE defines a new module for the current database. The name of the new module must be distinct from any existing module in the current database. Unlike SDL module declaration the CREATE MODULE command does not have sub-commands, as module contents are created separately.

Parameters

IF NOT EXISTS: Normally creating a module that already exists is an error, but with this flag the command will succeed. It is useful for scripts that add something to a module or if the module is missing the module is created as well.
