For example: @SET myNum = myNum + :val@ -- -- @SET@ supports the following functions: -- -- - @if_not_exists (path, operand)@ - if the item does not contain -- an attribute at the specified path, then @if_not_exists@ -- evaluates to operand; otherwise, it evaluates to path. You can -- use this function to avoid overwriting an attribute that may -- already be present in the item. -- -- - @list_append (operand, operand)@ - evaluates to a list with a -- new element added to it. You can append the new element to the -- start or the end of the list by reversing the order of the -- operands. -- -- These function names are case-sensitive. -- -- - @REMOVE@ - Removes one or more attributes from an item. -- -- - @ADD@ - Adds the specified value to the item, if the attribute does -- not already exist. If the attribute does exist, then the behavior of -- @ADD@ depends on the data type of the attribute: -- -- - If the existing attribute is a number, and if @Value@ is also a -- number, then @Value@ is mathematically added to the existing -- attribute. If @Value@ is a negative number, then it is -- subtracted from the existing attribute. -- -- If you use @ADD@ to increment or decrement a number value for an -- item that doesn\'t exist before the update, DynamoDB uses @0@ as -- the initial value. -- -- Similarly, if you use @ADD@ for an existing item to increment or -- decrement an attribute value that doesn\'t exist before the -- update, DynamoDB uses @0@ as the initial value. For example, -- suppose that the item you want to update doesn\'t have an -- attribute named @itemcount@, but you decide to @ADD@ the number -- @3@ to this attribute anyway. DynamoDB will create the -- @itemcount@ attribute, set its initial value to @0@, and finally -- add @3@ to it. The result will be a new @itemcount@ attribute in -- the item, with a value of @3@. -- -- - If the existing data type is a set and if @Value@ is also a set, -- then @Value@ is added to the existing set. For example, if the -- attribute value is the set @[1,2]@, and the @ADD@ action -- specified @[3]@, then the final attribute value is @[1,2,3]@. 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. -- -- Both sets must have the same primitive data type. For example, -- if the existing data type is a set of strings, the @Value@ must -- also be a set of strings. -- -- The @ADD@ action only supports Number and set data types. In -- addition, @ADD@ can only be used on top-level attributes, not nested -- attributes. -- -- - @DELETE@ - Deletes an element from a set. -- -- If a set of values is specified, then those values are subtracted -- from the old set. For example, if the attribute value was the set -- @[a,b,c]@ and the @DELETE@ action specifies @[a,c]@, then the final -- attribute value is @[b]@.
