MySQL Error

Error in SQL Query

select model_categorien.*,count(modelID) as aantal from model_categorien, modellen where modelCategorieID=categorieID and modelThumbnail > 0 and modelLanguage="nl" and categorieLanguage="nl" group by categorieOrder

Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'it-ernity_nxthome.model_categorien.categorieID' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
