如何删除 Dynamodb 中 table 的所有项目

Question

我尝试使用 AWS 中的 PartiQL 删除所有项目，但我收到了该消息

delete from myfile


An error occurred during the execution of the command.
ValidationException: Where clause does not contain a mandatory equality on all key attributes

Answer 1

看起来很简单...

ValidationException: Where clause does not contain a mandatory equality on all key attributes

如果你看docs

语法是

DELETE FROM table
WHERE condition [RETURNING returnvalues]

还有

condition (Required)
The selection criteria for the item to be deleted; this condition must resolve to a single primary key value.

如果要删除 DDB 中的所有记录，请删除 table 并重新创建它。

Answer 2

当我用双引号 (") 查询过滤器时出现此错误，但它们是单引号 (')，即使字段本身是双引号。

这是错误的方法（我和你有同样的错误）：

DELETE FROM "TABLE_A" WHERE "PK" = "<PK_A>" AND "SK" < "2022-03-27T14:10:00.000Z"

这是正确的方法（至少对我有用）：

DELETE FROM "TABLE_A" WHERE "PK" = '<PK_A>' AND "SK" < '2022-03-27T14:10:00.000Z'
