If SQLyog is complex then it is basically because MySQL is I think!
Anyway .. have you seen these: http://www.webyog.co…estimonials.php ? But I'd advice that you simply take time to read the help file (help .. help menu). Take the paragraphs for each feature as you start using them. And then there is of course the MySQL documentation: http://dev.mysql.com…/refman/5.5/en/ . The most important paragraphs for beginners are
* 10 Data Types
* 11 Functions and Operators
* 12 SQL Statement Syntax
