DDL packaging: in SQL, which statement can group multiple CREATE TABLE, CREATE VIEW, and GRANT commands to be issued together within a single, atomic schema definition?

Difficulty: Easy

Correct Answer: CREATE SCHEMA

Explanation:


Introduction / Context:
When initializing a new application schema, it is helpful to create tables, views, and privileges together to ensure the database is left in a consistent state. SQL provides a statement that lets you bundle such DDL in one logical unit.


Given Data / Assumptions:

  • We want to include CREATE TABLE, CREATE VIEW, and GRANT together.
  • The goal is atomicity and organization during schema deployment.
  • We reference broadly recognized SQL features (not vendor-specific packages).


Concept / Approach:
The CREATE SCHEMA statement defines a schema and can include a set of subordinate DDL statements within it. This lets a database apply the set as one coherent definition. CREATE PACKAGE is a program unit construct in some vendors (not generic SQL for DDL grouping). CREATE CLUSTER is a storage/organization feature in certain engines, unrelated to bundling mixed DDL with grants.


Step-by-Step Solution:

Identify the need: bundle multiple DDL statements.Map to the SQL feature designed for defining a schema atomically: CREATE SCHEMA.Exclude unrelated constructs (packages, clusters).


Verification / Alternative check:
Standards and vendor docs show CREATE SCHEMA supporting contained CREATE TABLE/VIEW and GRANT, applying them as one schema definition unit.


Why Other Options Are Wrong:

CREATE PACKAGE: program library feature, not general DDL bundling for tables/views/grants.CREATE CLUSTER: storage/segment concept, not transactionally bundling mixed DDL statements.All/None: incorrect because “CREATE SCHEMA” is the precise match.


Common Pitfalls:
Mixing transactional assumptions across engines; some databases auto-commit DDL, so use migration tools or explicit schema scripts for safe deployment.


Final Answer:
CREATE SCHEMA
