Lets say we have following tables
Table Pages:
id | short_name | long_name | token
1 | Mail | My mail box | mail
2 | All mails | All mails | all
3 | Inbox | Inbox only | inb
4 | Users | Users | users
5 | All users | All users | all
and table navigation:
id | parent_id | page_id
1 | 0 | 4
2 | 0 | 1
3 | 1 | 2
4 | 1 | 3
5 | 4 | 5
I was working with only page ids for a long time. It was easy to find details of page with only 1 value - $_GET['id'], because ids of pages all are unique.
Now, I want to create human readable (token based) navigation system.
But there is 1 problem. Tokens are not always unique.
For ex. index.php?page=mail&subpage=all and index.php?page=users&subpage=all
Can't figure out, how to find short_name and long_name (or other information of page) for these 2 pages (by 2 - $_GET['page'] and $_GET['subpage'] or more variables)?
Maybe I'm in wrong way. If you think so, please suggest your idea, and explain. Thx in advance.
Sorry if this doesn't work out of the box, but does this help?
SELECT * FROM Pages
JOIN navigation ON Pages.id=navigation.page_id
WHERE navigation.parent_id=(SELECT id FROM Pages WHERE token={$page})
AND Pages.token={$subpage}

Hello I am facing hard time trying to realized this task. The problem is that I am not sure in which way this have to be proceeded and couldn't find tutorials or information about realizing this type of task.
The question is I have 2 tables and one connecting table between the two of them. With regular query usually what is displayed is the table header which is known value and them then data. In My case I have to display the table horizontally and vertically since the header value is unknown value.
Here is example of the DB
Clients:
+--------+------ +
| ID | client|
+--------+------ +
| 1 | Sony |
| 2 | Dell |
+--------+------ +
Users:
+--------+---------+------------+
| ID | name | department |
+--------+--------+-------------+
| 1 | John | 1|
| 2 | Dave | 2|
| 3 | Michael| 1|
| 4 | Rich | 3|
+--------+--------+-------------+
Time:
+--------+------+---------------------+------------+
| ID | user | clientid | time | date |
+--------+------+---------------------+------------+
| 1 | 1 | 1 | 01:00:00 | 2017-01-02 |
| 2 | 2 | 2 | 02:00:00 | 2017-01-02 |
| 3 | 1 | 2 | 04:00:00 | 2017-02-02 | -> Result Not Selected since date is different
| 4 | 4 | 1 | 02:00:00 | 2017-01-02 |
| 5 | 1 | 1 | 02:00:00 | 2017-01-02 |
+--------+------+---------------------+------------+
Result Table
+------------+--------+-----------+---------+----------+
| Client | John | Michael | Rich | Dave |
+------------+--------+-----------+---------+----------+
| Sony |3:00:00 | 0 | 2:00:00 | 0 |
+------------+--------+-----------+---------+----------+
| Dell | 0 | 0 | 0 | 2:00:00 |
+------------+--------+-----------+---------+----------+
First table Clients Contains information about clients.
Second table Users Contains information about users
Third Table Time contains rows of time for each users dedicated to different clients from the clients table.
So my goal is to make a SQL Query which will show the Result table. In other words it will select sum of hours which every user have completed for certain client. The number of clients and users is unknown. So first thing that have to be done is Select all users, no matter if they have hours completed or not. After that have to select each client and the sum of hours for each client which was realized for individual user.
The problem is I don't know how to approach this situation. Do I have first to make one query slecting all users then foreach them in the table header and then realize second query selecting the hours and foreaching the body conent, or this can be made with single query which will render the whole table.
The filters for select command are:
WHERE MONTH(`date`) = '$month'
AND YEAR(`date`) ='$year'
AND u.department = '$department'
Selecting single row for tume SUM is:
(SELECT SUM( TIME_TO_SEC( `time` ) ) FROM Time tm
WHERE tm.clientid = c.id AND MONTH(`date`) = '$month' AND YEAR(`date`) ='$year'
This is the query to select the times for a user , here by my logic this might be transformed with GROUP BY c.id (client id), and the problem is that it have to contains another WHERE clause which will specify the USER which is unknown. If the users was known value was for example 5, there is no problem to make 5 subsequent for each user WHERE u.id = 1, 2, 3 etc.
So here are the 2 major problems how to display in same query The users header and them select the sum of hours for each client corresponding the user.
Check out the result table hope to make the things clear.
Any suggestion or answer which can come to resolve this situation will be very helpful.
Thank you!
I have a problem that I can't figure out, I'm not experienced enough (or it can't be done!) I've trawled Google for the answer with no luck.
I have a system where I need to assign an ID to each row, with the ID from another table. The catch is that the ID must be unique for each row created in this batch.
Basically I'm selling links on my Tumblr accounts, I need to assign a Tumblr account to each link that a customer purchases but I want to assign all possible Tumblr accounts so that duplicates are kept to the minimum possible.
The URLs - each link that a customer buys is stored in this table (urls_anchors):
+----------+--------------------+------------+-----------+------+
| clientID | URL | Anchor | tumblrID | paid |
+----------+--------------------+------------+-----------+------+
| 1234 | http://example.com | Click here | 67 | Yes |
| 1234 | http://example.com | Click here | 66 | Yes |
| 1234 | http://example.com | Click here | 65 | Yes |
| 1234 | http://example.com | Click here | 64 | Yes |
+----------+--------------------+------------+-----------+------+
All of the Tumblr accounts available for allocation are stored in this table (tumblrs):
+----------+-------------------+------------+
| tumblrID | tumblrURL | spacesLeft |
+----------+-------------------+------------+
| 64 | http://tumblr.com | 9 |
| 65 | http://tumblr.com | 9 |
| 66 | http://tumblr.com | 9 |
| 67 | http://tumblr.com | 9 |
+----------+-------------------+------------+
My best attempt at this has been the following query:
INSERT INTO `urls_anchors` (`clientID`, `URL`,`Anchor`, `tumblrID`, `paid`) VALUES ('$clientID','$url','$line', (SELECT #rank:=#rank+1 AS tumblrID FROM tumblrs WHERE #rank < 68 LIMIT 1), 'No')
Which works but keeps adding incrementally indefinitely, when there are only X number of Tumblrs to assign. I need the query to loop back around when it reaches the last row of Tumblrs and run through the list again.
Also i'm using this in a PHP script, I'm not sure if that's of any significance.
Any help would be MASSIVELY appreciated!
Thanks for looking :)
You can use a SELECT query as the source of data to insert.
INSERT INTO urls_anchors (`clientID`, `URL`,`Anchor`, `tumblrID`, `paid`)
SELECT '$clientID','$url','$line', tumblrID, 'No'
FROM tumblrs
LIMIT $number_of_rows
DEMO
This will assign $number_of_rows different tumblrID values to the rows.
If you need to assign more tumbler IDs than are available, you'll need to do this in a loop, subtracting the number of rows inserted from $number_of_rows each time. You can use mysqli_affected_rows() to find out how many rows were inserted each time.
i want to store views and like counts for the particular page .
im using page url is the unique key (index.php),
in my table i have the following columns
common table
id | page name | views | likes | timestamp
1 | index.php | 5 | 3 | 6-2-2014
2 | abount.php | 15 | 77 | 6-2-2014
for views table
id | page name | date | ip
1 | index.php | 6-2-2014 | 127.0.0.1
2 | index.php | 6-2-2014 | 127.0.0.2
3 | index.php | 6-2-2014 | 127.0.0.3
4 | index.php | 6-2-2014 | 127.0.0.4
5 | index.php | 6-2-2014 | 127.0.0.5
for like table
id | page name | date | ip
1 | index.php | 6-2-2014 | 127.0.0.1
2 | index.php | 6-2-2014 | 127.0.0.2
3 | index.php | 6-2-2014 | 127.0.0.3
what im did here means , every time i insert new record in count table i increase the count for particular page in the common table ,
1) Here i allowed only one time to like particular page from one IP.
2) i need to know how i get daily views and likes reports .
I know i have maintaining complicated tables , any simplification for this approach
sorry for my english
The comments about creating a foreign key for the page_id are good and you should look at those. However, your question was about how to get daily summary reports.
This will give you daily views (the same will apply for likes):
SELECT page_name, date, COUNT(ip) as viewcount
FROM views
GROUP BY page_name, date
ORDER BY page_name, date -- you can select any ordering...
OK, so this might sound complicated, let me explain... i've been banging my head on this for a while, and i'm stuck in a loop now... can't figure it out!
T1 is a simple alert data table. It's got theses headers :
| ID | TITLE | DATA |
---------------------------------
| 1 | Title1 | Text1 |
| 2 | Title2 | Text2 |
T2, is just a simple user table
| ID | Name |
-------------------
| 1 | Fred |
| 2 | Bill |
| 3 | Brad |
T3 is a link table between T1 and T2. Basically, the first time a user (T2.ID) views an alert (T1.ID) he hasn't viewed, his ID is added to this table so I know he's viewed it.
| ID | T1ID | T2ID |
--------------------------
| 1 | 1 | 1 |
| 2 | 1 | 2 |
| 3 | 1 | 3 |
| 4 | 2 | 2 |
| 5 | 2 | 3 |
| 6 | 3 | 1 |
| 7 | 3 | 3 |
I can tell user 1 has not viewed alert 2 nor has user 2 viewed alert 3. So next time they login, I should popup these alerts to them... So if i'm user 1, when I login my admin site, I want MySQL to tell me I havn't viewed alert 2, then UPDATE that table when I do.
As I sayed, T3 should build up everytime a user views an alert where his ID does not match an alert ID. I feel, i'm so damn close...
Simple enough, now how do I do it? I ain't going to post what doesn't work...
Please help...
The first thing, you want to start with the alert table as it is applicable to all uers. From there, doing a LEFT-JOIN to the already viewed table specifically for the login user ID in question AND the alert IDs are the same.
The where clause is looking ONLY for those entries that it CAN NOT find the corresponding login user ID as having viewed the alert. For those, get the alert's title and data.
After that, and presentation to the user, you can insert after the alerts have been viewed.
I would ensure the already viewed table has an index on both keys (T1ID, T2ID) to help optimize the join
SELECT
T1.Title,
T1.Data
from
YourAlertTable T1
LEFT JOIN AlreadyViewedTable T3
ON T3.T2ID = TheUserIDParameterWhoLoggedIn
AND T1.ID = T3.T1ID
where
T3.T2ID IS NULL
try :
Select * from t1 where id not in (select t3.t1id from t3 where t3.t2id = <loggedin userid>)
I used UserCake and it works fine, but now I need to connect created user accounts with modules (tables created in phpMyAdmin).
Simple I need to create menu with modules I managed and assigned to user.
User 1 after login will see for example; module2, module4
next User 2 will see: module3, module4
User 3: module1, module4
...
Assign must be managed only by me as admin. User only will get username & password and his package of assigned modules.
I hope I explained it good :).
You could make another table based on sth like:
[TABLE] user-has-modules:
id | userid | moduleid
0 | 0 | 0
1 | 0 | 1
2 | 0 | 2
3 | 1 | 0
4 | 1 | 1
5 | 2 | 0
6 | 2 | 2
[TABLE] users:
id | username | etc...
0 | 'blabla1'
1 | 'blabla2'
2 | 'blabla3'
3 | 'blabla4'
4 | 'blabla5'
[TABLE] modules:
id | name
0 | 'module1'
1 | 'module2'
2 | 'module3'
3 | 'module4'
4 | 'module5'
And then for the given user add or remove a table row afterwards. Later on you can choose the user over SQL and give/load the modules for the menu.
