Question

我正在尝试在我的数据库上使用两个UPDATE查询：

UPDATE equipment
SET equip_level = 'Hero'
WHERE equip = ('Amulet of Immortality');

UPDATE equipment
SET equip_level = 'Master'
WHERE equip = ('Shield of Pitch Black', 'Blade of MageBane', 'Leggings of Spikes', 'Gloves of Quickling skin', 'Helm of the Fire King', 'Scythe of Death');

第一个工作正常，但第二个（有多个条目）给出了以下错误：

[11:37:16] Error while executing SQL query on database 'test': row value misused

我正在查看的教程（https://digitalfellows.commons.gc.cuny.edu/2016/04/08/fun-times-with-sqlite-or-a-beginners-tutorial-to-data-management-and-databases-with-sql/）对第二个查询使用以下格式：

UPDATE equipment
SET equip_level = 'Master'
WHERE equip = IN ('Shield of Pitch Black', 'Blade of MageBane', 'Leggings of Spikes', 'Gloves of Quickling skin', 'Helm of the Fire King', 'Scythe of Death')

但是这给了我一个语法错误：

[11:49:48] Error while executing SQL query on database 'test': near "IN": syntax error

我该如何纠正？

Answer 1

删除等号：

UPDATE equipment
SET equip_level = 'Master'
WHERE equip IN ('Shield of Pitch Black', 'Blade of MageBane', 'Leggings of Spikes', 'Gloves of Quickling skin', 'Helm of the Fire King', 'Scythe of Death')
