It can be done using the below statement − CREATE TABLE table_name ( Let us see how a composite index can be created, during the creation of a table.

It can also be used for queries which will test the first columns, the first two columns, and so on. The query optimizer uses the composite indexes for queries which will test all columns in the index. MySQL allows the user to create a composite index which can consist of up to 16 columns.
