The Unit Test ezfSolrDocumentFieldBaseTest::testGetFieldName() throws an error because of the following SQL statement which assumes one column more than actually exists in the table ezcontentobject_link:

$q4 = "INSERT INTO ezcontentobject_link VALUES( {$ezcca4->attribute( 'id' )}, $srcObjId4, 1, 123456, 0, 8, $imageId4 );";
