如何在 birt 中使用 CASE WHEN 编写查询？

Question

我有这个：

SELECT
    CASE
        WHEN `ville_population_2012` < 500 THEN "Moins de 500 habitants"
        WHEN `ville_population_2012` >= 500 AND `ville_population_2012` <= 10000 THEN "Entre 500 et 10000 habitants"
        ELSE "Plus de 10000 habitants"
    END AS categorie,
    COUNT(*) AS nombre_villes
FROM `test`.villes_france_free
GROUP BY categorie;

phpmyadmin 的结果：
