If you look at the example below, you will see that using the index is actually slower. If it doesn't, it will go to the index, finding the matching pointers in the heap (table) and then go to the table to retrieve the data, making it slower. The planner is estimating that with just three rows, it will be faster to pull the three rows from the heap (table). Here is the actual table with index but not using it when querying the table I see the answer suggest this is small data hence it doesn't use index, so I can understand why its not using it here.īut I have the similar setup with the a char(255) column and added index of that column, but the table have 16 millions rows, and it also didn't use the index created, anyone know why? It seems a simple thing, but I can't figure out why its not working, does anyone know what is the cause of it? Its not using the index, just scan through the whole table Insert into test_index (name) values ('ken') Īfter created the table and data, I created an index for name column CREATE INDEX idx_test_index_shop_name ON test_index(name) īut when I do the simple query on name column select * from test_index where name = 'tom' Insert into test_index (name) values ('john')
