Q21

Multiple Choice

Which of the following SQL code snippets would correctly insert data into an Oracle database table while ensuring the application software handles NULL values appropriately?

SQL Code

INSERT INTO application_data (app_id, app_name, app_version)
VALUES (1, 'Software X', NULL);

INSERT INTO application_data (app_id, app_name, app_version)
VALUES (2, 'Software Y', '2.0');

INSERT INTO application_data (app_id, app_name, app_version)
VALUES (3, 'Software Z', DEFAULT);

The code correctly handles NULL values using NULL and DEFAULT. The code does not handle NULL values correctly. The code correctly uses DEFAULT for handling NULL values.The code incorrectly uses DEFAULT instead of NULL.

Option A and C handle NULL values correctly, ensuring application software can process incomplete data sets. Option B explicitly sets a version, which may not always be desired.

Q22

Multiple Choice

In an Oracle-based application software, which SQL code snippet would correctly modify a table structure by adding a new column with a default value?

SQL Code

ALTER TABLE application_data
ADD (release_date DATE DEFAULT SYSDATE);

ALTER TABLE application_data
ADD (release_notes VARCHAR2(255) DEFAULT 'Initial release');

ALTER TABLE application_data
ADD (is_active NUMBER(1) DEFAULT 1 NOT NULL);

Adds a new date column with the current system date as the default. Adds a new text column with a specific default string. Adds a new numeric column with a default value and a NOT NULL constraint.Removes a column instead of adding one.

Options A, B, and C are correct since they add new columns with default values in an Oracle table, aligning with application software requirements for default values.

Q23

Multiple Choice

Which of the following SQL code snippets correctly applies an update to application software version data in an Oracle database?

SQL Code

UPDATE application_data
SET app_version = '2.1' WHERE app_name = 'Software X';

UPDATE application_data
SET app_version = NULL WHERE app_name = 'Software Y';

UPDATE application_data
SET app_version = '3.0' WHERE app_name = 'Software Z';

Updates the version for Software X to 2.1. Sets the version to NULL for Software Y. Updates the version for Software Z to 3.0.Deletes version data for all applications.

Options A and C correctly update the application version data. Option B, which sets the version to NULL, is valid but may need additional handling in the application software.

Q24

Multiple Choice

Which SQL code snippet correctly creates a new Oracle table to store application software logs, including timestamps?

SQL Code

CREATE TABLE app_logs (
log_id NUMBER GENERATED ALWAYS AS IDENTITY,
log_message VARCHAR2(255),
log_timestamp TIMESTAMP DEFAULT SYSTIMESTAMP,
PRIMARY KEY (log_id));

CREATE TABLE app_logs (
log_id NUMBER,
log_message VARCHAR2(255) NOT NULL,
log_timestamp TIMESTAMP,
PRIMARY KEY (log_id));

Creates a table with an identity primary key and default timestamp. Creates a table with a manually specified primary key and optional timestamp. Creates a table without a primary key.Creates a table with an incorrect data type for log_id.

Options A and B correctly create a new table with a primary key and timestamp column. A uses an identity column for the primary key, which is common in application software.

Q25

Multiple Choice

Which SQL code snippet ensures data integrity in Oracle when entering application software license keys, making sure each key is unique?

SQL Code

CREATE TABLE app_licenses (
license_id NUMBER GENERATED ALWAYS AS IDENTITY,
license_key VARCHAR2(64) UNIQUE,
app_name VARCHAR2(255),
PRIMARY KEY (license_id));

ALTER TABLE app_licenses
ADD CONSTRAINT unique_license_key UNIQUE (license_key);

CREATE TABLE app_licenses (
license_key VARCHAR2(64),
app_name VARCHAR2(255),
CONSTRAINT license_key_pk PRIMARY KEY (license_key));

Creates a unique constraint on the license_key column. Adds a unique constraint to an existing table. Creates a primary key on the license_key column, ensuring uniqueness.Removes the unique constraint from the license_key column.

Options A, B, and C correctly enforce uniqueness for license keys in Oracle, crucial for application software handling licenses.

FETCH FIRST 10 ROWS ONLY;

SELECT log_message, log_timestamp FROM app_logs
ORDER BY log_timestamp DESC
FETCH NEXT 5 ROWS ONLY;

SELECT * FROM app_logs
ORDER BY log_timestamp DESC;

Retrieves the first 10 rows in descending order of timestamps. Fetches the next 5 rows after sorting by timestamps. Retrieves all rows sorted by timestamp without limiting the result.Retrieves rows in ascending order of timestamps.

Options A and B are efficient for retrieving the most recent log entries, which is crucial for application software requiring real-time data access.

WHERE app_name = 'Software X';

UPDATE application_data ad
SET ad.app_version = (SELECT av.latest_version FROM app_versions av WHERE av.app_name = ad.app_name)
WHERE ad.app_name IN ('Software X', 'Software Y');

Updates the version for a specific application using a subquery. Updates versions for multiple applications using a correlated subquery. Deletes data based on a subquery result.Inserts data based on a subquery result.

Options A and B use subqueries to update data in a table based on another table, a technique often required in complex application software scenarios.

FROM app_logs
GROUP BY app_name;

Groups logs by application name and counts entries. Groups logs by application name and sums log entries. Groups logs by timestamp only.Groups logs by a non-existent column.

Options A and B generate grouped reports based on application names, useful for creating summary reports in Oracle-based application software.

END;


BEGIN
INSERT INTO application_data (app_id, app_name, app_version)
VALUES (5, 'Software V', '1.1');
EXCEPTION
WHEN OTHERS THEN
RAISE_APPLICATION_ERROR(-20002, 'An unexpected error occurred.');
END;

Handles duplicate value errors and raises a custom error message. Handles all other errors with a general exception handler. Ignores errors during insertion.Terminates without handling any errors.

Options A and B correctly implement error handling, ensuring the application software can gracefully handle exceptions during database operations.
