mysql - how to include zeros in the count in only one single query -

enter image description here

will appreciate answers! thanks!

if there lookup-table, engagementtypes, possible values of engagement types stored, can query table full list of types , left join events table in order corresponding count:

select t1.engagement_type name, count(t2.engagement_type) y engagementtypes t1 left join events t2 on t1.engagement_type = t2.engagement_type group t1.engagement_type order t1.engagement_type
