I have a Database with the following two tables, member, POSTS I am looking for a way to get the count of how many posts a user has.

I have tried many variations of the following SQL command with out any success. instead of showing the count of posts for a single user it shows a single row with all the posts as the count.

In the end I want something like this

Might be that I’m missing something here, but this query would seem to give you the results you want:

SELECT member.ID,
       member.Name,
       (SELECT COUNT(*) FROM Posts WHERE member.ID = Posts.user_id) AS total
FROM   member;

I have left comment out of the query as it is not obvious what comment you want to be returned in that column for the group of comments that is counted.

See a SQL Fiddle demo here.

Edit
Sorry, misinterpreted your question 🙂 This query will properly return all the comments, along with the person who posted them and the total number of comments that the person made:

SELECT Posts.ID,
       member.Name,
       (SELECT COUNT(*) FROM Posts WHERE member.ID = Posts.user_id) AS total,
       Posts.comment
FROM   Posts
INNER JOIN member ON Posts.user_id = member.ID
GROUP BY Posts.ID, member.Name, member.ID, Posts.comment;
