A lakh or lac (/ˈlæk/ or /ˈlɑːk/; abbreviated L) is a unit in the Indian numbering system equal to one hundred thousand (100,000; scientific notation: 105). In the Indian convention of digit grouping, it is written as 1,00,000. For example, in India 150,000 rupees becomes 1.5 lakh rupees, written as ₹1,50,000 or INR 1,50,000.
It is widely used both in official and other contexts in Bangladesh, India, Myanmar, Nepal, Pakistan, and Sri Lanka. It is often used in Indian, Pakistani, and Sri Lankan English. In Pakistan, the word lakh is used mostly in local languages rather than in English media.

SELECT * FROM large ORDER BY `id` LI...
