Find Customer Start & End Points from Flight Data Using SQL

In this SQL problem-solving session, we analyze flight data to determine the start and end points of a customer's journey. Using real-world flight records, we demonstrate SQL joins, CASE statements, and aggregation techniques to efficiently process travel data. This session is perfect for data engineers, SQL learners, and professionals working with travel and logistics data, helping them understand how to derive meaningful insights from raw flight records. 📌𝐓𝐚𝐛𝐥𝐞 𝐂𝐫𝐞𝐚𝐭𝐢𝐨𝐧 & 𝐈𝐧𝐬𝐞𝐫𝐭𝐢𝐨𝐧 𝐒𝐜𝐫𝐢𝐩𝐭: CREATE TABLE flight_info(cust_id INT, flight_id VARCHAR(10), origin VARCHAR(50), destination VARCHAR(50)); INSERT INTO flight_info (cust_id, flight_id, origin, destination) VALUES (1, 'SG1234', 'Delhi', 'Hyderabad'), (1, 'SG3476', 'Kochi', 'Mangalore'), (1, '69876', 'Hyderabad', 'Kochi'), (2, '68749', 'Mumbai', 'Varanasi'), (2, 'SG5723', 'Varanasi', 'Delhi'), (3, '6E591', 'Goa','Lucknow'); 📌 𝐊𝐞𝐲 𝐒𝐐𝐋 𝐂𝐨𝐧𝐜𝐞𝐩𝐭𝐬 𝐂𝐨𝐯𝐞𝐫𝐞𝐝: ✔️ SQL Joins (Full Outer Join) ✔️ Data Aggregation with MAX ✔️ Conditional Logic with CASE Statements ✔️ Handling NULL values with ISNULL If you found this video helpful, like, share, and subscribe for more SQL problem-solving videos! 🚀 #SQL #DataAnalysis #SQLQuery #FlightData #DataEngineering #LearnSQL #SQLJoins #RealWorldSQL
