[−][src]Struct assemblylift_iomod_dynamodb_guest::structs::ConditionCheck
Represents a request to perform a check that an item exists or to check the condition of specific attributes of the item.
Fields
condition_expression: String
A condition that must be satisfied in order for a conditional update to succeed.
expression_attribute_names: Option<HashMap<String, String>>
One or more substitution tokens for attribute names in an expression.
expression_attribute_values: Option<HashMap<String, AttributeValue>>
One or more values that can be substituted in an expression.
key: HashMap<String, AttributeValue>
The primary key of the item to be checked. Each element consists of an attribute name and a value for that attribute.
return_values_on_condition_check_failure: Option<String>
Use ReturnValuesOnConditionCheckFailure
to get the item attributes if the ConditionCheck
condition fails. For ReturnValuesOnConditionCheckFailure
, the valid values are: NONE and ALL_OLD.
table_name: String
Name of the table for the check item request.
