SQL DDL knowledge check — confirm the command to define a view:\n“Is the SQL statement used to create a view named CREATE VIEW?” Choose the best evaluation.

Difficulty: Easy

Correct Answer: Correct

Explanation:


Introduction / Context:
Understanding core SQL Data Definition Language (DDL) verbs is foundational. This item checks whether you recognize the canonical syntax for defining a view. Views are named query definitions that present virtual tables to users and applications.



Given Data / Assumptions:

  • We refer to the standard SQL syntax for view creation.
  • Vendor extensions (e.g., OR REPLACE, FORCE, WITH CHECK OPTION) exist but do not change the base verb.
  • Privileges may affect execution but not the correctness of the statement name.


Concept / Approach:
The SQL statement to define a view is CREATE VIEW view_name AS SELECT .... This is consistent across SQL dialects, even if options differ. Therefore the assertion that the statement used is CREATE VIEW is correct. Variations like CREATE OR REPLACE VIEW or WITH CHECK OPTION refine behavior but do not alter the fundamental DDL verb.



Step-by-Step Solution:

Identify the required DDL verb for defining a view.Confirm the canonical syntax: CREATE VIEW ... AS SELECT ...Recognize optional clauses that may appear.Conclude the claim is correct.


Verification / Alternative check:
Consult any major vendor documentation; each provides CREATE VIEW with dialect-specific options (e.g., security barriers, schemabinding, column lists), but the verb remains CREATE VIEW.



Why Other Options Are Wrong:

  • “Incorrect” and “MAKE VIEW” contradict the standard.
  • “Only correct with WITH CHECK OPTION” confuses a constraint clause with the DDL verb.
  • “Indeterminate” is irrelevant; privileges do not rename the statement.


Common Pitfalls:
Confusing vendor options with the standard verb; assuming that inability to execute (due to permissions) changes the correctness of the statement name.



Final Answer:
Correct
