#1

SELECT IncidentStatus.IncidentStatusName, COUNT(Incident.IncidentID) AS Bob  
  FROM Incident 
INNER JOIN IncidentMember ON Incident.IncidentID = IncidentMember.IncidentId 
INNER JOIN IncidentStatus ON Incident.IncidentStatusID = IncidentStatus.IncidentStatusID 
WHERE (IncidentMember.MemberId = 6)
GROUP BY IncidentStatus.IncidentStatusName

Or maybe you need COUNT(DISTINCT Incident.IncidentID) (depends on your table structure)

或者您可能需要COUNT（DISTINCT Incident.IncidentID）（取决于您的表结构）

#2

take your PK field, Incident.IncidentID, out of the select distinct clause

从您的PK字段Incident.IncidentID中取出select distinct子句
