I asked my friend Chatty, can you use recursion in SQL? For example I have a table (ID, value) ordered by increasing ID. Can you guide me through using recursion to select all the rows of consecutive repeated values using and creating an SQLite database. Provide the small sample data. Is there a better way to do this? A More Modern Alternative (Window Functions) In real-world SQL, this problem is usually solved more efficiently using window functions like: LAG() ROW_NUMBER() SUM() OVER But recursion is excellent for learning traversal logic and hierarchical thinking. Recursion example using sqlite on termux DROP TABLE IF EXISTS sample; CREATE TABLE sample ( id INTEGER PRIMARY KEY, value TEXT ); INSERT INTO sample (id, value) VALUES (1, 'A'), (2, 'A'), (3, 'A'), (4, 'B'), (5, 'B'), (6, 'C'), (7, 'A'), (8, 'A'), (9, 'D'), (10, 'D'), (11, 'D'), (12, 'D'); WITH RECURSIVE grouped AS ( ...
