SELECT * FROM COMPANY INDEXED BY salary_index WHERE SALARY > 50000 This time I make an index like this after dropping the older one: CREATE INDEX IF NOT EXISTS salary_index on COMPANY (SALARY)ДЄfter I added the index, I did: SELECT * FROM COMPANY Д®xpecting that IвЂ™d see only the ones with salary higher than 50000, but I saw people lower than that.ДЄnd I also tried to do this: SELECT * FROM COMPANY INDEXED BY salary_index
