Question

I am trying to find out how many comments there are in a question that has been made by the owner of the page (the admin).

tblQuestion: (question table)

queID
queUserID
queCompanyID (the owner of the page where questions are asked)

tblReplies: (where comments in the question are saved)

repQuestionID (queID = parent ID)
repUserID (the user ID who made the comment)

tblUsers: (where the users are stored)

uID (user ID, autoincrement)
uCompanyID (if this id is the same as a company id, the user is admin of that page)

So, I want to know how many reply posts are made by the company owner (a user with uCompanyID the reply posts’ parent companyID – queCompanyID).

I tried doing this to get number of posts made by page admin, but does not seem to work:

SELECT COUNT(*) tblReplies.repID
FROM tblReplies
JOIN 
    tblQuestions ON tblQuestions.queID = tblReplies.repQuestionID
JOIN 
    tblUsers ON tblQuestions.queCompanyID = tblUsers.uCompanyID
WHERE tblQuestions.queID = 68 AND tblUsers.uCompanyID = 1

I really hope there is a ninja out there who can help me, I’ve spent hours and still nothing.

Thanks!

Answer 1

This should work (assuming there is a userID on the tblUsers table.:

SELECT 
    count(*), 
    tblReplies.repID
FROM 
    tblReplies, 
    tblQuestions, 
    tblUsers
WHERE
    tblQuestions.queID = tblReplies.repQuestionID AND
    tblQuestions.queCompanyID = tblUsers.uCompanyID AND
    tblUser.uID = tblReplies.repUserID AND
    tblUsers.uCompanyID = 1 AND 
    tblQuestions.queID = 68 

GROUP BY tblReplies.repID
