Same name in other branches
- 9 core/modules/views/views.api.php \hook_views_query_substitutions()

- 11.x core/modules/views/views.api.php \hook_views_query_substitutions()
Replace special strings in the query before it is executed.
The idea is that certain dynamic values can be placed in a query when it is built, and substituted at run-time, allowing the query to be cached and still work correctly when executed.
Parameters
\Drupal\views\ViewExecutable $view: The View being executed.
Return value
array An associative array where each key is a string to be replaced, and the corresponding value is its replacement. The strings to replace are often surrounded with '***', as illustrated in the example implementation, to avoid collisions with other values in the query.
