sqlite3的錯誤：行值missused

Question

我想在我的數據庫使用兩個UPDATE查詢：

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'); 

第一個工作得很好，但第二個（有多個條目）給了我以下錯誤：

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

，我正在看（https://digitalfellows.commons.gc.cuny.edu/2016/04/08/fun-times-with-sqlite-or-a-beginners-tutorial-to-data-management-and-databases-with-sql/）本教程使用以下格式第二個查詢：

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，這給了我一個語法錯誤：

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

我如何糾正呢？

Answer 1

去除等號：

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')
