Add FORCE INDEX with drupal query builder
问题 I am developing a website using Drupal 7 . I was using a query with the help of function db_query . But now I am planning to restructure it and use the db_select format. But at one portion, I am using a FORCE INDEX() to force the use a particular index to overcome a drawback of old MySql version. Is there any way to add this force index with the join() in db_select? 来源： https://stackoverflow.com/questions/52215360/add-force-index-with-drupal-query-builder
