I was wondering if SPARQL had an equivalent of the SQL "update" query? Where would I find a tutorial for it for beginners?

SPARQL and SQL have very similar UNION and MINUS operators, which respectively add and remove solutions from a solution set. Because the datatypes of an SQL table are assumed to be uniform across all rows, care must be taken to align the datatypes of the SELECT.
SPARQL/Update supports two categories of update operations on a Graph Store: Graph Update - addition and removal of triples from one of the graphs in the graph store. Graph Management - creating and deletion of graphs within the graph store.
SPARQL, short for “SPARQL Protocol and RDF Query Language”, enables users to query information from databases or any data source that can be mapped to RDF. The SPARQL standard is designed and endorsed by the W3C and helps users and developers focus on what they would like to know instead of how a database is organized.
SPARQL is a recursive acronym, which stands for SPARQL Protocol and RDF Query Language. SPARQL consists of two parts: query language and protocol. The query part of that is pretty straightforward. SQL is used to query relational data. XQuery is used to query XML data.
Yes – SPARQL Update, new in SPARQL 1.1. I highly recommend Bob DuCharme's Learning SPARQL book. I'm not aware of any good beginner's tutorials, but if you know how to query data with SPARQL, then the examples in the SPARQL Update specification should help you to get started.
