Question
Which of the following SQL statements should be used to create a table in a database?
Question 8
Select one:
- a. DDL
- b. DCL
- c. DML
- d. DAL
Solution
Break Down the Problem
- Identify the purpose of each SQL category: Data Definition Language (DDL), Data Control Language (DCL), Data Manipulation Language (DML), and Data Access Language (DAL).
- Determine which category is responsible for creating tables.
Relevant Concepts
- DDL (Data Definition Language): Used to define (create, alter, drop) the structure of a database.
- DCL (Data Control Language): Used for controlling access to data in the database.
- DML (Data Manipulation Language): Used for managing data within schema objects (e.g., insert, update, delete).
- DAL (Data Access Language): Generally refers to APIs or methods for interacting with data, but not a standard SQL classification.
Analysis and Detail
- The SQL statement used to create a table typically comes from DDL, with the command being
CREATE TABLE
. - DCL is more concerned with permissions and rights.
- DML does not define structures; it operates on the data itself.
- DAL is not a standard SQL category.
Verify and Summarize
Considering the roles of each SQL category, the appropriate statement to create a table falls under DDL.
Final Answer
a. DDL is the correct choice for the SQL statement used to create a table in a database.
