Whilst there are many ways for building and executing SQL queries in Zend Framework 2, the two that I usually use, and which are also used in the ZF2 manual, are closures and the selectWith function. I previously wrote a three part series, showing how to get started using the \Zend\Db\Sql classes with Zend Framework 2, but I didn’t cover how to actually run them. So in today’s tutorial, let’s do that.
Are TableGateways too hard to implement in Zend Framework 2? Too hard to justify the effort? That’s what I was asked recently. So I’ve written this post to show why they’re not, and how they bring great flexibility, when implemented correctly.
In part 3 of this series on \Zend\Db\Sql\Select in Zend Framework 2 We cover the constructor, columns function, aliases and expressions, finishing up with limit and order functions. Come wind up the series in style.
In part two of the \Zend\Db\Sql\Select series, we create inner, outer, left and right joins as well as union queries with ease. Come learn more about building queries simply, effectively and easily in your every day applications with Zend Framework 2.
In this tutorial we’re working through the basics of \Zend\Db\Sql\Where, showing how to build SQL Where clauses for database queries. We’ll show how to create different predicates from simple to nested queries using of and, or, like, between and in conditions.
