For example, suppose that the item you want to update does not yet have an attribute named <i>itemcount</i>, but you decide to <code>ADD</code> the number <code>3</code> to this attribute anyway, even though it currently does not exist. DynamoDB will create the <i>itemcount</i> attribute, set its initial value to <code>0</code>, and finally add <code>3</code> to it. The result will be a new <i>itemcount</i> attribute in the item, with a value of <code>3</code>.</p> </note> </li> <li> <p>If the existing data type is a set, and if the <code>Value</code> is also a set, then the <code>Value</code> is added to the existing set. (This is a <i>set</i> operation, not mathematical addition.) For example, if the attribute value was the set <code>[1,2]</code>, and the <code>ADD</code> action specified <code>[3]</code>, then the final attribute value would be <code>[1,2,3]</code>. An error occurs if an Add action is specified for a set attribute and the attribute type specified does not match the existing set type. </p> <p>Both sets must have the same primitive data type. For example, if the existing data type is a set of strings, the <code>Value</code> must also be a set of strings. The same holds true for number sets and binary sets.</p> </li> </ul> <p>This action is only valid for an existing attribute whose data type is number or is a set. Do not use <code>ADD</code> for any other data types.</p> </li> </ul> <p> <b>If no item with the specified <i>Key</i> is found:</b> </p> <ul> <li> <p> <code>PUT</code> - DynamoDB creates a new item with the specified primary key, and then adds the attribute. </p> </li> <li> <p> <code>DELETE</code> - Nothing happens; there is no attribute to delete.</p> </li> <li> <p> <code>ADD</code> - DynamoDB creates an item with the supplied primary key and number (or set of numbers) for the attribute value.

For example, suppose that the item you want to update doesn't have an attribute named <code>itemcount</code>, but you decide to <code>ADD</code> the number <code>3</code> to this attribute anyway.

An error occurs if an <code>ADD</code> action is specified for a set attribute and the attribute type specified does not match the existing set type. </p> <p>Both sets must have the same primitive data type. For example, if the existing data type is a set of strings, the <code>Value</code> must also be a set of strings.</p> </li> </ul> <important> <p>The <code>ADD</code> action only supports Number and set data types. In addition, <code>ADD</code> can only be used on top-level attributes, not nested attributes.</p> </important> </li> <li> <p> <code>DELETE</code> - Deletes an element from a set.</p> <p>If a set of values is specified, then those values are subtracted from the old set.
