JDBC Input from last document_id


I´m using Logstash with JDBC to connect to a Microsoft SQL Server.
My Table (or query) return a datetime and a id field.
Since last_run_metadata_path saves on a different time format than SQL Server, I´d like to query new data from my id field.
Is it possible?

PS: Logstash 2.0 / Elasticsearch 2.0 / Kibana 4.2.1
