| You may try those three queries : CREATE TEMPORARY TABLE tmp SELECT name1 AS name, COUNT(*) AS nbr FROM cities GROUP BY name1; INSERT INTO tmp SELECT name2 AS name, COUNT(*) AS nbr FROM cities GROUP BY name2; SELECT * FROM tmp; NB : your table layout is not adapted at all to the queries you wanna run ;-) |
