Drupal 7.43 / CIVICRM 4.7.7
I am trying to find contacts with no emails (any type eg/ Home, Other) using Search Builder. Using either IS EMPTY or IS NULL, I end up with no result but get a DB error. Viz: Sorry but we are not able to provide this at the moment. One of parameters (value: Home-email) is not of the type MysqlColumnName
It doesn't seem to matter what operator I use, the result is the same. Please help. Ian
