Sql删除多个带有多个标识符的行

Question

我试图删除多行两个标识符：

DELETE FROM [Customers] 
WHERE (City,Country) IN (('Buenos Aires', 'Argentina'), ('Graz', 'Austria'))

我收到此错误：

Error 1: could not prepare statement (1 row value misused)

无法删除多个标识符的多行？

Answer 1

如果您的数据库不支持元组，只需使用显式AND / OR逻辑：

DELETE FROM [Customers] 
WHERE (City = 'Buenos Aires' AND Country = 'Argentina') OR
      (City = 'Graz' AND Country = 'Austria');
