ConditionalOperator (legacy) - Amazon DynamoDB (original) (raw)

Note

We recommend that you use the new expression parameters instead of these legacy parameters whenever possible. For more information, see Using expressions in DynamoDB.

The legacy conditional parameter ConditionalOperator is a logical operator used to apply to the conditions in a Expected,QueryFilter or ScanFilter map:

• AND - If all of the conditions evaluate to true, then the entire map evaluates to true.
• OR - If at least one of the conditions evaluates to true, then the entire map evaluates to true.

If you omit ConditionalOperator, then AND is the default.

The operation will succeed only if the entire map evaluates to true.

Note

This parameter does not support attributes of type List or Map.
