2️⃣ Variables
Used to store data in memory that can be used later.
name = "Alice"
age = 25
3️⃣ Data Types
Python supports various built-in types like integers, strings, floats, booleans, lists, and dictionaries.
x = 10 # int
pi = 3.14 # float
text = "Hi" # string
is_valid = True # bool
colors = ["red", "blue"] # list
user = {"name": "Bob", "age": 30} # dictionary
4️⃣ Conditional Statements
Used to make decisions based on conditions (if, elif, else).
if age >= 18:
print("Adult")
else:
print("Minor")
5️⃣ Loops
Used to repeat a block of code.
for loop
for i in range(3):
print(i)
while loop
count = 0
while count < 3:
print(count)
count += 1
6️⃣ Functions
Reusable blocks of code that perform a task.
def greet(name):
return f"Hello, {name}"
print(greet("Sara"))
7️⃣ Lists
Ordered, mutable collection of items.
fruits = ["apple", "banana", "cherry"]
print(fruits[1]) # banana
8️⃣ Dictionaries
Stores data as key-value pairs.
person = {"name": "John", "age": 30}
print(person["name"])
9️⃣ File Handling
Used to read/write files.
with open("data.txt", "r") as file:
content = file.read()
print(content)

💬 Tap ❤️ for more!PRIMARY KEY – Uniquely identifies each row
- FOREIGN KEY – Links to another table
- UNIQUE – Ensures all values are different
- NOT NULL – Column must have a value
- CHECK – Validates data before insert/update
2️⃣ SQL Views:
Virtual tables based on result of a query
CREATE VIEW top_students AS
SELECT name, marks FROM students WHERE marks > 90;
3️⃣ Indexing:
Improves query performance
CREATE INDEX idx_name ON employees(name);
4️⃣ SQL Transactions:
Ensure data integrity
BEGIN;
UPDATE accounts SET balance = balance - 100 WHERE id = 1;
UPDATE accounts SET balance = balance + 100 WHERE id = 2;
COMMIT;
5️⃣ Triggers:
Automatic actions when events occur
CREATE TRIGGER log_update
AFTER UPDATE ON employees
FOR EACH ROW
INSERT INTO logs(action) VALUES ('Employee updated');
6️⃣ Stored Procedures:
Reusable blocks of SQL logic
CREATE PROCEDURE getTopStudents()
BEGIN
SELECT * FROM students WHERE marks > 90;
END;
7️⃣ Common Table Expressions (CTEs):
Temporary named result sets
WITH dept_count AS (
SELECT department, COUNT(*) AS total FROM employees GROUP BY department
)
SELECT * FROM dept_count;
