C# Class Amazon.DynamoDBv2.Model.DeleteItemRequest

Container for the parameters to the DeleteItem operation.

Deletes a single item in a table by primary key. You can perform a conditional delete operation that deletes the item if it exists, or if it has an expected attribute value.

In addition to deleting an item, you can also return the item's attribute values in the same operation, using the ReturnValues parameter.

Unless you specify conditions, the DeleteItem is an idempotent operation; running it multiple times on the same item or attribute does not result in an error response.

Conditional deletes are useful for only deleting items if specific conditions are met. If those conditions are met, Amazon DynamoDB performs the delete. Otherwise, the item is not deleted.

Method Details

DeleteItemRequest() public method

Empty constructor used to set properties independently even when a simple constructor is available

public DeleteItemRequest ( ) : System
return	System

DeleteItemRequest() public method

Instantiates DeleteItemRequest with the parameterized properties

public DeleteItemRequest ( string tableName, AttributeValue>.Dictionary key ) : System
tableName	string	The name of the table from which to delete the item.
key	AttributeValue>.Dictionary	A map of attribute names to AttributeValue objects, representing the primary key of the item to delete. For the primary key, you must provide all of the attributes. For example, with a simple primary key, you only need to provide a value for the partition key. For a composite primary key, you must provide values for both the partition key and the sort key.
return	System

DeleteItemRequest() public method

Instantiates DeleteItemRequest with the parameterized properties

public DeleteItemRequest ( string tableName, AttributeValue>.Dictionary key, ReturnValue returnValues ) : System
tableName	string	The name of the table from which to delete the item.
key	AttributeValue>.Dictionary	A map of attribute names to AttributeValue objects, representing the primary key of the item to delete. For the primary key, you must provide all of the attributes. For example, with a simple primary key, you only need to provide a value for the partition key. For a composite primary key, you must provide values for both the partition key and the sort key.
returnValues	ReturnValue	Use ReturnValues if you want to get the item attributes as they appeared before they were deleted. For DeleteItem, the valid values are: `NONE` - If ReturnValues is not specified, or if its value is `NONE`, then nothing is returned. (This setting is the default for ReturnValues.) `ALL_OLD` - The content of the old item is returned. The ReturnValues parameter is used by several DynamoDB operations; however, DeleteItem does not recognize any values other than `NONE` or `ALL_OLD`.
