*

* The condition can optionally perform one of several comparison tests on a single sort key value. This allows * Query to retrieve one item with a given partition key value and sort key value, or several items * that have the same partition key value but different sort key values. *

*

* The partition key equality test is required, and must be specified in the following format: *

*

* partitionKeyName = :partitionkeyval *

*

* If you also want to provide a condition for the sort key, it must be combined using AND with the * condition for the sort key. Following is an example, using the = comparison operator for the sort key: *

*

* partitionKeyName = :partitionkeyval AND * sortKeyName = :sortkeyval *

*

* Valid comparisons for the sort key condition are as follows: *

*
    *
  • *

    * sortKeyName = :sortkeyval - true if the sort key value is equal to * :sortkeyval. *

    *
  • *
  • *

    * sortKeyName < :sortkeyval - true if the sort key value is less than * :sortkeyval. *

    * sortKeyName <= :sortkeyval - true if the sort key value is less than or * equal to :sortkeyval. *

    *
  • *
  • *

    * sortKeyName > :sortkeyval - true if the sort key value is greater than * :sortkeyval. *

    *
  • *
  • *

    * sortKeyName >= :sortkeyval - true if the sort key value is greater * than or equal to :sortkeyval. *

    *
  • *
  • *

    * sortKeyName BETWEEN :sortkeyval1 AND * :sortkeyval2 - true if the sort key value is greater than or equal to :sortkeyval1, and * less than or equal to :sortkeyval2. *

    *
  • *
  • *

    * begins_with ( sortKeyName, :sortkeyval ) - true if the sort * key value begins with a particular operand. (You cannot use this function with a sort key that is of type * Number.) Note that the function name begins_with is case-sensitive. *

    *
  • *
*

* Use the ExpressionAttributeValues parameter to replace tokens such as :partitionval and * :sortval with actual values at runtime. *

*

* You can optionally use the ExpressionAttributeNames parameter to replace the names of the partition * key and sort key with placeholder tokens. This option might be necessary if an attribute name conflicts with a * DynamoDB reserved word. For example, the following KeyConditionExpression parameter causes an error * because Size is a reserved word: *

*
    *
  • *

    * Size = :myval *

    *
  • *
*

* To work around this, define a placeholder (such a #S) to represent the attribute name Size. * KeyConditionExpression then is as follows: *

*
    *
  • *

    * #S = :myval *

    *
  • *
