Overview
When making an API call, you may pass Delete data as a hash:
{
key: { # required
"AttributeName" => "value", # value <Hash,Array,String,Numeric,Boolean,IO,Set,nil>
},
table_name: "TableName", # required
condition_expression: "ConditionExpression",
expression_attribute_names: {
"ExpressionAttributeNameVariable" => "AttributeName",
},
expression_attribute_values: {
"ExpressionAttributeValueVariable" => "value", # value <Hash,Array,String,Numeric,Boolean,IO,Set,nil>
},
return_values_on_condition_check_failure: "ALL_OLD", # accepts ALL_OLD, NONE
}
Represents a request to perform a ‘DeleteItem` operation.
