In Mysql, if you want to either updates or inserts a row in a table, depending if the table already has a row that matches the data, you can use “ON DUPLICATE KEY UPDATE”.
How to do it in Sqlite?
Use “INSERT OR REPLACE INTO” .
INSERT OR REPLACE INTO Employee (id, name, role) VALUES (1, 'John Foo', 'CEO');
