Mysql无线值查询：重置所有值并更改一个

我有两个查询，其中第一个查询将所有字段置为零，第二个查询将更新列，但我希望这些查询先进入on query change cover_image=0，然后进入cover_image=1

Update gallery set cover_image = 0 Where gallery_id = 1;
Update gallery set cover_image = 1 Where ID = 4 AND gallery_id = 1;

我怎样用一个查询就能做到这一点呢？

我刚刚找到了答案

UPDATE gallery SET cover_image = IF(id='4', '1','0') WHERE gallery_id = 1

等于

Update gallery set cover_image = 0 Where gallery_id = 1;
Update gallery set cover_image = 1 Where ID = 4 AND gallery_id = 1;

如果只想合并这些查询，请将标题更改为更明确。
