Namespace

Drupal\workspaces\EntityQuery

Code

public function prepare() {

  // Aggregate entity queries do not return an array of entity IDs keyed by
  // revision IDs, they only return the values of the aggregated fields, so we
  // don't need to add any expressions like we do in
  // \Drupal\workspaces\EntityQuery\Query::prepare().
  $this
    ->traitPrepare();

  // Throw away the ID fields.
  $this->sqlFields = [];
