我不确定这个术语是什么，但我有一个 mysql 查询
SELECT name, invTypes.typeName, character_skills.trained_skill_level FROM character_skills INNER JOIN character_infos ON character_infos.character_id = character_skills.character_id INNER JOIN invTypes ON character_skills.skill_id = invTypes.typeID WHERE character_skills.active_skill_level <5 AND skill_id = 12203 AND name = 'Mokey PYD';
但是，有 2 个变量会发生变化，我需要在一个表中显示所有这些。
这两个变量是
WHERE character_skills.active_skill_level <5 AND skill_id = 12203
例如
我需要查看 active_skill_level is < 5 的值是否对于 skill_id 12203但还需要检查是否 active_skill_level < 4对于 skill_id 12204我需要这些显示在同一张 table 上...
有人可以帮我一下吗？非常感谢。
最佳答案
使用UNION ALL
SELECT name, invTypes.typeName, character_skills.trained_skill_level
FROM character_skills INNER JOIN character_infos ON character_infos.character_id = character_skills.character_id
INNER JOIN invTypes ON character_skills.skill_id = invTypes.typeID
WHERE character_skills.active_skill_level <5 AND skill_id = 12203 AND name = 'Mokey PYD'
union all
SELECT name, invTypes.typeName, character_skills.trained_skill_level
FROM character_skills INNER JOIN character_infos ON character_infos.character_id = character_skills.character_id
INNER JOIN invTypes ON character_skills.skill_id = invTypes.typeID
WHERE character_skills.active_skill_level <4 AND skill_id = 12204 AND name = 'Mokey PYD'
