Is it a good idea to index datetime field in mysql?
... But if you query the data with date range, such as data range from "2017-01-01 11:20" to "2018-01-03 12:12", it doesn't make SELECT query faster even though I indexed date time column... index make query fast when I use equal operation.. Am i right?
