Cheatah: Abfrage schlecht aufgebaut?

Beitrag lesen

Hi,

SELECT
article,
(SELECT IF((EXISTS(SELECT * FROM articles WHERE artnum LIKE CONCAT(article,'%red'))),1,0)) AS red,
(SELECT IF((EXISTS(SELECT * FROM articles WHERE artnum LIKE CONCAT(article,'%green'))),1,0)) as green,
(SELECT IF((EXISTS(SELECT * FROM articles WHERE artnum LIKE CONCAT(article,'%orange'))),1,0)) as orange
FROM fav
ORDER BY clicks DESC LIMIT 20

Hat jemand eine Idee, wie ich das ganze beschleunigen kann?

ersetze erst mal das "%" durch ein "-".

Cheatah
