Hook_views_query_alter Drupal 8

Views query alter is used to edit the query in views that we created using Drupal. In cases where we cannot add fields in views, we can use hook_views_query_alter to change the query in views.

Example of views query alter by using join.

Here we added join using class views_join in Drupal. It's a built-in function to represent a join and to create the SQL necessary to implement the join.

Configure views for debugging in the advanced settings. Celebrate 20 years of Drupal with us! April is DrupalFest, a month-long series of virtual events focused on community, contribution, and the positive impacts made possible with Drupal. Define functions that alter the behavior of Drupal core. One way for modules to alter the core behavior of Drupal (or another module) is to use hooks. Hooks are specially-named functions that a module defines (this is known as 'implementing the hook'), which are discovered and called at specific times to alter or add to the base behavior.
