我在下面的引导代码中使用下拉菜单。我发现它可以在Chrome和Firefox上正常使用,但是当我们在iOS的Safari中使用它时,则无法正常工作。
SELECT id_mk, npm_mhs, MAX(nilai_mk)
FROM
(
SELECT id_mk, npm_mhs, nilai_mk FROM nilai_lama
UNION ALL
SELECT id_mk, npm_mhs, nilai_mk FROM nilai_baru
UNION ALL
SELECT id_mk, npm_mhs, nilai_mk FROM nilai_konversi
)A
WHERE A.npm_mhs = '18.14.1.0003'
GROUP BY id_mk,npm_mhs
预先感谢
