SQL is a 4GL type language used by the majority of database systems (Sybase, MSSQL, Oracle etc) to access and manipulate the data in the databases. In my opinion it is easy to learn and does not really require great efforts. You just need to practice. I would like to take this opportunity and recommend the most recent Sybase Transact SQL book written by myself and Ryan Putnam titled Sybase Transact SQL Guidelines Best Practices. This book is recently published by Sybase Inc. and covers up to ASE 12.5.2.
Good luck and happy reading.
