What are the different clause necessary for manipulating with tables in DynamoDB

Question

Updating tables in MySQL is easier it seems. In DynamoDB i have tried the same but always found something missing. Can someone help me with the clause necessary for updating a table in DynamoDB?

Answer 1

The different update clause in DynamoDb are as follows:

• SET: Used to add an attribute to an Item or modify an existing attribute.
• REMOVE: Used to delete attributes from an Item.
• ADD: Used to increment/decrement a Number or insert elements into a Set.
• DELETE: Used to remove items from a Set.
