Not

import "github.com/aws/aws-sdk-go/service/dynamodb/expression"

func Not(conditionBuilder ConditionBuilder) ConditionBuilder

Not returns a ConditionBuilder representing the logical NOT clause of the argument ConditionBuilder. The resulting ConditionBuilder can be used as a part of other Condition Expressions or as an argument to the WithCondition() method for the Builder struct.

Example:

// condition represents the condition where the item attribute "Name" // does not begin with "test" condition := expression.Not(expression.Name("Name").BeginsWith("test")) // Used in another Condition Expression anotherCondition := expression.Not(condition) // Used to make an Builder builder := expression.NewBuilder().WithCondition(condition)

Expression Equivalent:

expression.Not(expression.Name("Name").BeginsWith("test")) // Let :prefix be an ExpressionAttributeValue representing the value // "test" "NOT (begins_with (:prefix))"

conditionBuilder

ConditionBuilder represents Condition Expressions and Filter Expressions in DynamoDB. ConditionBuilders are one of the building blocks of the Builder struct. Since Filter Expressions support all the same functions and formats as Condition Expressions, ConditionBuilders represents both types of Expressions.
