function EntityFieldQuery::addCondition

Adds a condition to an already built SelectQuery (internal function).

This is a helper for hook_entity_query() and hook_field_storage_query().

Parameters

SelectQuery $select_query: A SelectQuery object.

$sql_field: The name of the field.

$condition: A condition as described in EntityFieldQuery::fieldCondition() and EntityFieldQuery::entityCondition().

$having: HAVING or WHERE. This is necessary because SQL can't handle WHERE conditions on aliased columns.

    $like_prefix = '';
    switch ($condition['operator']) {
        case 'CONTAINS':
            $like_prefix = '%';
        case 'STARTS_WITH':
            $select_query->{$method}($sql_field, $like_prefix . db_like($condition['value']) . '%', 'LIKE');
            break;
        default:
            $select_query->{$method}($sql_field, $condition['value'], $condition['operator']);
    }
