A Database Error Occurred

Error Number: 1055

Expression #12 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'eastwell_breeze3.forms_formPart.formPart_PK' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

SELECT *, COUNT(`form_PK`) AS form_count FROM (`forms_field`) LEFT JOIN `forms_formPart` ON field_PK = formPart_fieldFK LEFT JOIN `forms_form` ON formPart_formFK = form_PK WHERE (form_deleted IS NULL OR form_deleted = 0) GROUP BY `field_PK` ORDER BY `field_name`
