Lee Feigenbaum's SPARQL by Example is always a good place to start.

If you have specific questions you'll find a helpful bunch of people containing many SPARQL experts at answers.semanticweb.com

Please pardon the shameless plug, but O'Reilly recently released my book "Learning SPARQL," which so far is the only book on the query language. As title implies, it's more about getting up to speed with SPARQL than about providing a complete reference work. The book covers both SPARQL 1.0 and 1.1. See learningsparql.com for more; all sample queries and data are available on the website.

If you like jumping to examples first, you can refer the official W3C specifications document http://www.w3.org/TR/2013/REC-sparql11-query-20130321/

Contains a good amount of examples , and are edited by top people . Should take about less than 10 minutes to finish too
