protected function ViewsQueryAlter::moveEntityTable in Drupal 8

Same name and namespace in other branches

1. 9 core/modules/workspaces/src/ViewsQueryAlter.php \Drupal\workspaces\ViewsQueryAlter::moveEntityTable()

Moves a 'workspace_association' table to appear before the given alias.

Because Workspace chains possibly pre-existing tables onto the 'workspace_association' table, we have to ensure that the 'workspace_association' table appears in the query before the alias it's chained on or the SQL is invalid.

Parameters

\Drupal\views\Plugin\views\query\Sql $query: The SQL query object.

string $workspace_association_table: The alias of the 'workspace_association' table.

string $alias: The alias of the table it needs to appear before.
