The way to create a composite index in MySQL is by using the CREATE INDEX statement.

The syntax is as follows:
CREATE INDEX index_name ON table_name (column1, column2, …);

For example, creating a joint index with two columns would look like this:
CREATE INDEX idx_name ON table_name (column1, column2);

In the example above, idx_name is the name of the index, table_name is the name of the table, and column1 and column2 are the names of the columns to be included in the index. This will create a composite index that will make search operations on column1 and column2 more efficient.
