질문 # 47
Which clause from a SELECT statement immediately accompanies the SELECT clause in MySQL?

A. WHERE
B. FROM
C. VALUE
D. TABLE

정답：B

설명：
InSQL syntax, the FROM clause is the first clause that follows SELECT. It specifies the table(s) from which the data will be retrieved.
Example:
sql
SELECT name, salary FROM Employees;
* Option A (Correct):The FROM clauseimmediately followsthe SELECT clause in MySQL.
* Option B (Incorrect):VALUE is not a valid clause in MySQL SELECT statements.
* Option C (Incorrect):WHERE is used to filter recordsafter specifying the table in FROM.
* Option D (Incorrect):TABLE is not a valid clause following SELECT in SQL.

질문 # 48
Which statement uses valid syntax for the DELETE statement in SQL?

A. DELETE * FROM table_name WHERE condition;
B. DELETE FROM table_name;
C. DELETE table_name WHERE condition;
D. DELETE FROM table_name WHERE condition;

정답：D

설명：
Thecorrect syntaxfor deleting records from a table in SQL is:
sql
DELETE FROM table_name WHERE condition;
This deletesonly the rowsthat match the condition.
Example Usage:
sql
DELETE FROM Employees WHERE Salary < 30000;
* Deletesall employees earning less than $30,000.
Why Other Options Are Incorrect:
* Option A (Incorrect):Missing FROMkeyword. The correct syntax is DELETE FROM table_name.
* Option C (Partially Correct):DELETE FROM table_name;deletes all rows, but it lacks a WHERE clause.
* Option D (Incorrect):DELETE *is not validin SQL. The correct command is just DELETE FROM.
Thus, the correct answer isDELETE FROM table_name WHERE condition;.

질문 # 49
Which relationship or association exists between a supertype and its subtype entities?

A. Associative entity
B. Weak entity
C. Strong entity
D. IsA relationship

정답：D

설명：
Indatabase modeling, the relationship between asupertype and its subtypesis called anIsA relationship.
Example Usage:
* AVehicle supertypemay haveCar and Truck subtypes.
Vehicle
### Car
### Truck
* InER diagrams, this is represented as:
Vehicle (Supertype)
|
### Car (Subtype)
### Truck (Subtype)
* SQL Table Implementation:
sql
CREATE TABLE Vehicle (
VehicleID INT PRIMARY KEY,
Make VARCHAR(50),
Model VARCHAR(50)
);
CREATE TABLE Car (
VehicleID INT PRIMARY KEY,
FOREIGN KEY (VehicleID) REFERENCES Vehicle(VehicleID),
EngineType VARCHAR(50)
);
CREATE TABLE Truck (
VehicleID INT PRIMARY KEY,
FOREIGN KEY (VehicleID) REFERENCES Vehicle(VehicleID),
CargoCapacity INT
);
* This structurepreserves the IsA relationshipbetween Vehicle (supertype) and Car/Truck (subtypes).
Why Other Options Are Incorrect:
* Option A (Strong entity) (Incorrect):Strong entitiesdo not rely on a supertype/subtype hierarchy.
* Option C (Associative entity) (Incorrect):Used toresolve many-to-many relationships, not supertype
/subtype relationships.
* Option D (Weak entity) (Incorrect):Weak entitiesdepend on a strong entity, but supertype-subtype relations useinheritance(not dependency).
Thus, the correct answer isIsA relationship, as it describes theinheritance hierarchybetweensupertypes and subtypes.

질문 # 50
Which type of entity only exists in a logical sense?

A. Tangible entity
B. Intangible entity
C. Concrete entity

These entities representconcepts, relationships, or abstract datathat exist in a logical sense.
Example Usage in Databases:
* Customer Loyalty Status (Gold, Silver, Bronze)
* Theloyalty levelis anintangible entitysince it is derived from other data (purchase history).
* Online User Sessions
* Asession IDexistslogically in the systembut does not have a tangible presence like a product or employee.
Why Other Options Are Incorrect:
* Option A (Concrete entity) (Incorrect):No such formal term in database design.
* Option B (Tangible entity) (Incorrect):Represents somethingphysical, like anemployeeorproduct.
* Option D (Physical entity) (Incorrect):Refers todata stored on disk, like database tables or indexes.
Thus, the correct answer isIntangible entity, as it only exists in a logical sense within the database.

A. INSERT Employee { "John Doe" };
B. INSERT INTO Employee ("John Doe");
C. INSERT INTO Employee (Name) VALUES ("John Doe");
D. INSERT Employee (Name) Values ("John Doe");

정답：C

설명：

Standard SQL INSERT Syntax:
sql
INSERT INTO TableName (Column1, Column2, ...)
VALUES (Value1, Value2, ...);
For this scenario:
sql
INSERT INTO Employee (Name) VALUES ('John Doe');
Why Other Options Are Incorrect:
