Which of the following commands is part of DDL?

AUPDATE

BGRANT

CCREATE

DINSERT

Show Suggested Answer

Suggested Answer: C

The command that is part of DDL is CREATE. CREATE is a SQL command that belongs to the category of DDL, or Data Definition Language. DDL is a subset of SQL commands that are used to define or modify the structure or schema of a database, such as tables, columns, constraints, indexes, views, etc. CREATE is a DDL command that is used to create a new object in a database, such as a table, column, constraint, index, view, etc. For example, the following statement uses the CREATE command to create a new table called employee with four columns:

CREATE TABLE employee (

emp_id INT PRIMARY KEY,

emp_name VARCHAR(50) NOT NULL,

emp_dept VARCHAR(20),

emp_salary DECIMAL(10,2)

);

Copy

The other options are either part of different categories of SQL commands or not SQL commands at all. For example, UPDATE is a SQL command that belongs to the category of DML, or Data Manipulation Language. DML is a subset of SQL commands that are used to manipulate or modify the data or content of a database, such as inserting, updating, deleting, or selecting data. GRANT is a SQL command that belongs to the category of DCL, or Data Control Language. DCL is a subset of SQL commands that are used to control or manage the access or permissions of users or roles on a database, such as granting or revoking privileges or roles. INSERT is a SQL command that belongs to the category of DML, or Data Manipulation Language. INSERT is a DML command that is used to insert new data into a table.Reference:CompTIA DataSys+ Course Outline, Domain 1.0 Database Fundamentals, Objective 1.2 Given a scenario, execute database tasks using scripting and programming languages.

I'm not sure, but UPDATE and INSERT sound more like DML commands for manipulating data

Haha, this question is like asking whether a fork is part of the cutlery family. Of course CREATE is DDL! If anyone picks the other options, they'll be forking up their certification.

Haha, remember that time in our study group when we got into a heated debate about the differences between DDL and DML? Good times.

Yeah, the CREATE command is a no-brainer. But I'm a bit worried about the other options. GRANT is related to permissions, and UPDATE and INSERT are Data Manipulation Language (DML) commands. I hope the rest of the exam isn't this easy.

You know, I'm not totally sure about this, but I think UPDATE and INSERT are DML (Data Manipulation Language) commands, not DDL. So I'm going to go with C) CREATE.

I agree with Scarlet. CREATE is definitely a DDL command, used to create database objects like tables, views, and indexes. I'm surprised they're including such a basic SQL question in a certification exam.

Hmm, this seems like a pretty straightforward SQL question. I'm pretty confident that CREATE is part of the Data Definition Language (DDL).

I'm leaning towards C) CREATE. That's probably the most common DDL command, used to create tables, views, indexes, and other database objects.

Yeah, that makes sense. So I'm guessing the answer is either B) GRANT or C) CREATE. Those seem like the most likely DDL commands.

I agree with Kenia. I think the DDL commands are the ones that deal with the structure of the database, not the actual data itself.

Hmm, this is a tricky one. I know DDL stands for Data Definition Language, so it's probably related to creating, modifying, or deleting database objects, not data manipulation.
