(SQL Server) SQS Delete Message

Deletes a message from an SQS queue. You specify the message by using the message's receipt handle and not the message ID you received when you sent the message. This example will first receive a message, and then use the receipt handle to delete it.

See SQS DeleteMessage or detailed information.
