Delete Attributes

simpledb_delete_attributes

R Documentation

Deletes one or more attributes associated with an item¶

Description¶

Deletes one or more attributes associated with an item. If all attributes of the item are deleted, the item is deleted.

If delete_attributes is called without being passed any attributes or values specified, all the attributes for the item are deleted.

delete_attributes is an idempotent operation; running it multiple times on the same item or attribute does not result in an error response.

Because Amazon SimpleDB makes multiple copies of item data and uses an eventual consistency update model, performing a get_attributes or select operation (read) immediately after a delete_attributes or put_attributes operation (write) might not return updated item data.

Usage¶

simpledb_delete_attributes(DomainName, ItemName, Attributes, Expected)

Arguments¶

DomainName: [required] The name of the domain in which to perform the operation.
ItemName: [required] The name of the item. Similar to rows on a spreadsheet, items represent individual objects that contain one or more value-attribute pairs.
Attributes: A list of Attributes. Similar to columns on a spreadsheet, attributes represent categories of data that can be assigned to items.
Expected: The update condition which, if specified, determines whether the specified attributes will be deleted or not. The update condition must be satisfied in order for this request to be processed and the attributes to be deleted.

Value¶

An empty list.

Request syntax¶
