    1. COThank you for the quick response. I have three questions regarding your answer: 1. Can you please explain "COUNT(IF(ISNULL(pv.private_id) AND p.private<>'0' AND p.user_id<>'1', null, 1))" in detail? It seems to work but I can't figure out what all the parts do/mean. 2. If we use $logged_in_id as 7, which doesn't exist. We still get results. Does this make sense? Also, what if a user is logged out, so $logged_in_id='', would the query be the same? 3.If not using the threads table, I feel the counting will be too heavy on each page reload. Do you suggest this as the most efficient solution?

    2. CO**1.** **COUNT()** will count records where the content of the function is not null. That is what the **IF(,null,1)** is for. **2.** Added af join to users as 'auth' to do authentication. This will return 0 records if user not logged in (both '7' and '') **3.** Yes I agree if the number of posts will be become large over time, then I would prefer maintaining a count rather than query it every time.

    3. COFor easier readability and logic I turned the IF into a CASE like this: COUNT(case when ISNULL(pv.private_id) AND p.private='1' AND p.user_id='3' then null else 1 end) Is this correct? Instead of p.private<>'0', and p.user_id<>'1' (as there will be more than users 1 & 3), I put the above p.private='1', and p.user_id='3'. Also, why would it mess up the count id we put 0 instead of null in the then else?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
