Instantiates UpdateItemRequest with the parameterized properties
public UpdateItemRequest( String tableName, Dictionary<String, AttributeValue> key, Dictionary<String, AttributeValueUpdate> attributeUpdates, ReturnValue returnValues )
The name of the table containing the item to update.
The primary key of the item to be updated. Each element consists of an attribute name and a value for that attribute. 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.
This is a legacy parameter. Use UpdateExpression instead. For more information, see AttributeUpdates in the Amazon DynamoDB Developer Guide.
Use ReturnValues if you want to get the item attributes as they appear before or after they are updated. For UpdateItem, 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 - Returns all of the attributes of the item, as they appeared before the UpdateItem operation. UPDATED_OLD - Returns only the updated attributes, as they appeared before the UpdateItem operation. ALL_NEW - Returns all of the attributes of the item, as they appear after the UpdateItem operation. UPDATED_NEW - Returns only the updated attributes, as they appear after the UpdateItem operation. There is no additional cost associated with requesting a return value aside from the small network and processing overhead of receiving a larger response. No read capacity units are consumed. The values returned are strongly consistent.
