For an operation to be completed on an item, you have to specify a condition.
You can define a ConditionExpression that can be constructed from the following:
  • Boolean functions: ATTRIBUTE_EXIST, CONTAINS, and BEGINS_WITH
  • Comparison operators: =, <>, <, >, <=, >=, BETWEEN, and IN
  • Logical operators: NOT, AND, and OR. 

You can also construct a free-form conditional expression that combines multiple conditional clauses which also includes nested clauses.
