Drupal db select

With Drupal 8, significant changes has been brought for developers: new features and backwards-compatible changes, new APIs, deprecated modules, and more. One of the biggest changes is Drupal 8's unified database query API that fundamentally alters the way most Drupal developers will build database queries in Drupal. Allow the use of different database servers using the same code base. Drupal provides a database abstraction layer to provide developers with the ability to support multiple database servers easily. The intent of this layer is to preserve the syntax and power of SQL as much as possible, but also allow developers a way to leverage more complex functionality in a unified way.

The release of Drupal 7 has brought a lot of changes for developers: new features, updated APIs, deprecated modules, and more. One of the biggest changes is Drupal 7's new database API, an object-oriented system that fundamentally alters the way most developers will build database queries in Drupal. In this article, we'll take a look at how the new API dramatically simplified one contrib module's complex code, and how to spot similar opportunities in your own code. First, a bit of background. In addition, it uses an object-oriented approach to building complex SQL queries that delights some developers while baffling and frustrating others. Rather than writing a SQL query in raw text and calling a helper function to execute the query, developers create a "query" object, call methods on it to add fields, filters, sorts, and other query elements, then call the query object's "execute" method. While it may not sound like a big difference, it's a real shift for those who are used to hand-writing their SQL. Take a look at the following example:. Both of these code snippets are doing the same thing: pulling the id, title, and author id from columns in the Node table that match certain criteria, then sorting the results and ensuring only 5 matches are returned.

Jeremy founded Tag1 Consulting in He has been a contributing core Drupal developer since , and helped establish Drupal as a successful CMS through the early popularity of his personal blog, KernelTrap. Over the years, he authored and maintained the core statistics module and throttle module, as well as the pager logic and the initial Drupal 5 installer.
