I'm looking for the right syntax using Zend db to show a table that is sorted by the count. For example, my mysql table looks like this:
Users Description
1 topic1
1 topic2
2 topic3
I want the output to look like:
User 1 (2 descriptions)
User 2 (1 description)
The raw query you're looking for
SELECT users, COUNT(*) count
FROM table1
GROUP BY users
ORDER BY COUNT(*) DESC
Output:
| USERS | COUNT |
|-------|-------|
| 1 | 2 |
| 2 | 1 |
Here is SQLFiddle demo
I'm not an expert in Zend but your query may look something between the lines of
$select = $db->select()
->from('table1', array('users', 'count' => '(COUNT(*))'))
->group('users')
->order('(COUNT(*)) DESC');
$stmt = $db->query($select);
$result = $stmt->fetchAll();

This is my sql outcome:
What I am trying to achieve is to show the garden and under that it shows the hose pipe ,lawn moar etc.
How to write the query?
If I understand you correct you would normaly do that somehow like that.
cat_id | parent_id | cat_name | cat order
1 0 Garden 1
2 1 Hose Pipe 1
3 1 Lawn Moar 2
in this case Garden for example would have the cat_id 1 and parent_id 0 and all subcategories have their own incremented id and the parent_id of garden, which would be 1 in this case!
then you can query for your categories and foreach of them query for the subcategories where the parent_id is the cat_id of the maincategory!
here you have a nice tutorial on how to display it recursive:

that way you also only need to save the imagepath only once in your maincat!

In my MySQL database, I'm trying way of creating a table to track daily views on 100 items. Each day would insert a new row for each item. So the table columns would look like this:
| ItemID | ItemName | Hits |
Is there a way to store daily hits for items?
What you could do is have a table with a structure like:
| item_hits |
|---------------|
| itemID | date |
Then your SQL query could look like
SELECT count(*) FROM item_hits WHERE date = '2015/04/15' and itemID = 7;
You wouldn't need to save the itemName in the table, because you should be able to get the itemName by joining it to your items table.

I am really not good at math, but can someone help me though how i can get the place the user has on all entries? Etc. "You are now number 43 out of 20.403.044 entries"?
SELECT ?myPlace? FROM entries WHERE userid = 1 ORDER BY time ASC
ok, i think you want
SELECT COUNT(*) FROM TABLE WHERE id <= YOUR_USER_ID
You can get the rank with this query:
SELECT COUNT(*) + 1
FROM entries entries1
INNER JOIN entries entries2 ON (entries1.id != entries2.id AND entries2.time < entries1.time)
WHERE entries1.id = 4
You just need to count the number of people with a better time, and add 1 (since the first rank is 1).
Unfortunately MySQL lacks windowing functions. Therefore you have emulate them. One way to do it is something like this
SELECT userid,
(
SELECT 1 + COUNT(*)
FROM entries
WHERE time < e.time
) place
FROM entries e
WHERE userid = 1
Sample output:
| USERID | PLACE |
|--------|-------|
| 1 | 2 |
If you need total number of entries in the same query
SELECT userid,
(
SELECT 1 + COUNT(*)
FROM entries
WHERE time < e.time
) place,
(
SELECT COUNT(*)
FROM entries
) total
FROM entries e
WHERE userid = 1;
Sample output:
| USERID | PLACE | TOTAL |
|--------|-------|-------|
| 1 | 2 | 5 |

I have a table which looks like this one:
| id | fk_book | name |
-----------------------
| 1 | 2 | test1|
| 3 | 2 | test3|
| 6 | 3 | notes|
| 7 | 2 | test2|
No I want to get the entry with the id 3. select * from test where id=3 AND fk_book=1;
but is there also a way to get the item with id 1 and 7?
and I dont know the ids of the other entries
thanks
I think you need this:
select * from test where id=3 AND fk_book = 2
union all
select * from test where id < 3 AND fk_book = 2 order by id desc limit 1
union all
select * from test where id > 3 AND fk_book = 2 order by id asc limit 1
Try following sql query:
select * from test where id in(1,3,7);
