Properties

ConditionExpression

Gets a condition on the existing item that must hold, for example "attribute_exists(pk) AND version = :expected". When it does not hold, the whole transaction is cancelled and the reason for this action is ConditionalCheckFailed. Attribute names that are DynamoDB reserved words, such as name, status, size, order or total, must be aliased with a #placeholder defined in ExpressionAttributeNames; written directly, DynamoDB rejects the request with a ValidationException. See the list of reserved words.

public string? ConditionExpression { get; init; }

Property Value

string

ExpressionAttributeNames

Gets the substitutions for #name placeholders in ConditionExpression. Use it to alias attribute names that are DynamoDB reserved words, such as name, status, size, order or total, which DynamoDB rejects with a ValidationException when an expression uses them directly (the check is case-insensitive), and names with a dot or other special characters. See the list of reserved words.

public IReadOnlyDictionary<string, string>? ExpressionAttributeNames { get; init; }

Property Value

IReadOnlyDictionary<string, string>

ExpressionAttributeValues

Gets the substitutions for :value placeholders in ConditionExpression.

public IReadOnlyDictionary<string, AttributeValue>? ExpressionAttributeValues { get; init; }

Property Value

IReadOnlyDictionary<string, AttributeValue>

Key

Gets the full primary key of the item: the partition key and, if the table has one, the sort key.

public required IReadOnlyDictionary<string, AttributeValue> Key { get; init; }

Property Value

IReadOnlyDictionary<string, AttributeValue>

ReturnValuesOnConditionCheckFailure

Gets whether a failed condition returns the existing item in Item.

public ReturnValuesOnConditionCheckFailure ReturnValuesOnConditionCheckFailure { get; init; }

Property Value

ReturnValuesOnConditionCheckFailure

TableName

Gets the table name (or table ARN).

public required string TableName { get; init; }

Property Value

string
