CREATE TABLE xvisitors2 ( year char(4) NOT NULL, month char(3) NOT NULL, number int(10) NOT NULL ) ENGINE=CONNECT; INSERT INTO xvisitors2 SELECT * FROM xvisitors;
Now we can create a new PIVOT table:
CREATE TABLE pvisitors ENGINE=CONNECT TABLE_TYPE=PIVOT TABNAME=xvisitors2;
You should now be used to the TABLE_TYPE and TABNAME options, which specify the table type and the source table respectively.

You can now run the following query to check if the PIVOT operation has been realized:
SELECT * FROM pvisitors;
