Delete

interface Delete

The Delete clause may be used to remove elements from sets. See the low-level DynamoDB documentation for more details on the underlying features and capabilities.

Set values may be removed by using the -= operator (or the minusAssign method):

delete {
    attr["foo"] -= setOf(42) // Removes the element `42` from attribute `foo`
}

Properties

abstract val attr: Attr

Accesses an attribute path reference from a top-level attribute name in this update expression (e.g., attr["foo"] references the "foo" attribute of items being updated)
