Example: If using JavaScript, you might use the filter method: students.filter(student ...
This SQL query retrieves student names with a CGPA between 8 and 9 from the student database.
SQL Query Structure: The query uses the SELECT statement to specify the column (stdname) to retrieve from the student table.
BETWEEN Operator: The BETWEEN operator is used to filter records where the CGPA falls within the specified range (8 to 9).
Data Retrieval: This query will return all student names whose CGPA is greater...
To find the top two maximum salaries from the emp table, we can use SQL queries with ORDER BY and LIMIT clauses.
Use SQL query: SELECT DISTINCT salary FROM emp ORDER BY salary DESC LIMIT 2;
DISTINCT ensures unique salary values are considered.
ORDER BY salary DESC sorts the salaries in descending order.
LIMIT 2 restricts the output to the top two salaries.
The program checks if a given sentence is a palindrome or not.
Prompt the user to input a sentence
Remove all spaces and punctuation from the sentence
Reverse the sentence and compare it with the original sentence to check for palindrome
count(*) counts all rows in a table, while count(column_name) counts non-null values in a specific column.
count(*) counts all rows in a table
count(column_name) counts non-null values in a specific column
count(*) is generally used to get the total number of rows in a table
count(column_name) is used to count non-null values in a specific column
Languages based in SQL include T-SQL, PL/SQL, and SQL/PSM.
T-SQL (Transact-SQL) is Microsoft's proprietary extension to SQL used in SQL Server.
PL/SQL (Procedural Language/SQL) is Oracle's procedural language extension to SQL.
SQL/PSM (SQL/Persistent Stored Modules) is a standard for defining stored procedures and functions in SQL.
Object-oriented programming concepts that focus on classes and objects
Encapsulation: bundling data and methods that operate on the data within a single unit
Inheritance: ability of a class to inherit properties and behavior from another class
Polymorphism: ability to present the same interface for different data types
Abstraction: hiding the complex implementation details and showing only the necessary features
To find the second highest salary, we can use SQL queries with various methods like subqueries or the DISTINCT clause.
Use a subquery: SELECT MAX(salary) FROM employees WHERE salary < (SELECT MAX(salary) FROM employees);
Use DISTINCT: SELECT DISTINCT salary FROM employees ORDER BY salary DESC LIMIT 1 OFFSET 1;
Use ROW_NUMBER(): SELECT salary FROM (SELECT salary, ROW_NUMBER() OVER (ORDER BY salary DESC) AS rank FRO...

Overriding in Java allows a subclass to provide a specific implementation of a method that is already provided by its superclass.
Inheritance is a key concept in overriding, where a subclass inherits methods from its superclass.
To override a method, the method in the subclass must have the same name, return type, and parameters as the method in the superclass.
The @Override annotation can be used to ensure that a method ...
Inheritance in Java allows a class to inherit properties and behaviors from another class.
Allows for code reusability and promotes the concept of 'is-a' relationship
Subclass inherits fields and methods from superclass
Can override methods in subclass to provide specific implementation
Super keyword is used to access superclass methods and fields
Example: class Dog extends Animal {}
