I have a mysql database. When I enter the data in a table[T_ID, T_Name, T_AGE] (say around 10k rows.) Will the database implicitly create indexes for this table. If so, then what will happen if I create index my-self using “Create Index .. ON say T_ID”. Will both the indexes exists or which one will actually be present.
If you specify
primary key(t_id)then it will create automaticaly an index and you won’t be able to create another one on the same column.why you don’t try these cases?
