I have 5 table,
user, plan, achievement, user_plan, user_achievement
The strucutre
User
id
name
Plan
id
name
achievement
id
name
*planID
user_plan
*planid
*userid
user_achievement
*achievementid
*userid
*createDate
And I use Codeigniter (Doesn't matter , what I would like to have is the mysql query)
$this->db->select('*');
$this->db->from('user');
$query = $this->db->get();
Actually, for each plan , there is a list of achievement, if it is not achieved, it is not stored at the user_achievement, so how can I get "for each user, get 1) his name 2)the plan he joins, and 3)the achievement he achieve and not achieve (need to highlight the achieved)"?
Thanks.
use join
$this->db->select('i.id,u.name,up.planid,p.name as planname,ua.achievementid,ach.name as ach_name');
$this->db->from('user as u');
$this->db->join('user_plan as up','up.userid = u.id','left');
$this->db->join('plan as p','p.id = up.planid','left');
$this->db->join('user_achievement as ua','ua.userid = u.id','left');
$this->db->join('achievement as ach','ach.id = ua.achievementid','left');
$query = $this->db->get();
You need to LEFT JOIN between tables user, plan,achievement and user_achievement like below
select u.name as username,
p.name as planname,
a.name as achivementname
from User u
left join user_achievement ua on u.id = ua.userid
and ua.createDate is not null
left join achivement a on ua.achievementid = a.id
left join Plan p on a.planid = p.id

I made a query that user can see all the post of active users but not of those inactive, but also they should not see the post of users they blocked or blocked them how can I do that?, the block_users table has block_by_userid and blocked_userid column.
I tried INNER JOIN the post table with members table which every inactive users post cannot be seen anymore., How will I combine the block_users table?
$GetPost = "SELECT Post.* FROM Post
INNER JOIN Members ON Post.Poster_user_id = Members.User_id
WHERE Status='active'";
you might try FULL OUTER JOIN
the idea it to get all items in both tables member and block_users and then filter the data using where clause, i am sorry if i miss using the fields name , so please check the tables names, i assume block_users.block_by_userid contained the blocked user id if not use the correct field
$GetPost = "SELECT Post.* FROM Post
INNER JOIN Members ON Post.Poster_user_id = Members.User_id
FULL OUTER JOIN block_users ON Members.User_id = block_users.user_id
WHERE Status='active'
AND
WHERE block_users.block_by_userid != Members.User_id";
Suppose I am doing this for a user xyz whose user_id is 123 then below is a query which will return expected output for user 123.
Query:
SELECT Post.* FROM Post
INNER JOIN Members ON Post.Poster_user_id = Members.User_id
WHERE Status='active' and post.poster_user_id NOT IN(select block_by_userid from block_users where blocked_user_id = 123 UNION select blocked_user_id from block_users where block_by_userid = 123)
First is a user table, second a places table and third a favorites table (having two fk, one from user and another from places). I want to get all the favorite places of one user, how do I do that?
I tried to play around with joins but what I don't know is how to get data of a particular user.
$qry =
"SELECT places.place_id , places.db_image ,places.description from places
inner join favorites on places.place_id = favorites.place_id
inner join user on user.id = favorites.user_id
";
$query=mysqli_query($con ,$qry);
$return_arr = array();
$sql = sprintf(
'SELECT
p.place_id,
p.db_image,
p.description
FROM
places p INNER JOIN
favorites f ON p.place_id = f.place_id INNER JOIN
user u ON u.id = f.user_id
WHERE
u.id = %d'
, $userId);
or if you want simply select all columns from places
SELECT
p.*
FROM
places p INNER JOIN
favorites f ON p.place_id = f.place_id INNER JOIN
user u ON u.id = f.user_id
WHERE
u.id = %d
It is better to use prepared statements, but if you are not familiar with them, this is good enough.
i need help getting data from different tables and insert into other different table Here are the Queries
"SELECT commentID, date, comment, subject, parentID, aBUserID FROM comments WHERE status = 'APPROVED'"
"SELECT topicID, subForumID, aBUserID, lastPostID, views, replies, startDate FROM topic WHERE status = 'APPROVED' AND topicID = $parentid";
// $parentID need to be matched from above query parentID,
"SELECT userName FROM users WHERE aBUserID = $cmtaBUserID";
// $cmtaBUserID = aBUserID from first query
"SELECT userName FROM users WHERE aBUserID = $topicaBUserID";
//$topicaBUserID = aBUserID from second query
Last 2 queries are from same table but using different where clause
i used different inner join left join from solutions posted here but non of these worked for me stuck since last 2 weeks please help
PS data from all above Queries will be inserted to a single table i need these to be combined so i can have them all in one place
If you want to perform the operation in same query use 'OR'
"SELECT userName FROM users WHERE aBUserID = $cmtaBUserID OR aBUserID = $topicaBUserID";
Please try this
SELECT userName from users where aBUserID IN(SELECT aBUserID FROM comments WHERE status = 'APPROVED')
Couldn't test it but Maybe this is what you are looking for.
SELECT c.commentID, c.date, c.comment, c.subject, c.parentID, c.aBUserID,
t.topicID, t.subForumID, t.aBUserID, t.lastPostID, t.views, t.replies, t.startDate,
u.userName
FROM
comments c
left outer join topic t on t.topicID = c.parentID
left outer join users u on u.aBUserID = c.aBUserID and u.aBUserID = t.aBUserID
WHERE
c.status = 'APPROVED' and t.status = 'APPROVED';
try this:
SELECT
comment.[commentID],
comment.[date],
comment.[comment],
comment.[subject],
comment.[parentID],
comment.[aBUserID],
commentuser.[userName],
topic.[topicID],
topic.[subForumID],
topic.[aBUserID],
topic.[lastPostID],
topic.[views],
topic.[replies],
topic.[startDate],
topic.[userName]
FROM comments comment
LEFT OUTER JOIN users commentuser
ON commentuser.aBUserID = comment.[aBUserID]
LEFT OUTER JOIN
(
SELECT
t.[topicID],
t.[subForumID],
t.[aBUserID],
t.[lastPostID],
t.[views],
t.[replies],
t.[startDate],
u2.[userName] --user from users table joined to topics table
FROM topic t
LEFT OUTER JOIN users u
ON u.aBUserID = t.[aBUserID]
WHERE t.[status] = 'APPROVED'
) topic
ON topic.topicID = comment.parentID
WHERE comment.[status] = 'APPROVED'
hello please help me out regarding this query ,I am fetching data from different table The problem i am facing is that in the table there are similar colum name like employee have and user has also name . The query work perfectly but i am wordering about how i can display this data as
$data["employee.name"]
$data["user.name"]
here is the query:
SELECT task.employee_id , task.user_id , task.service_id, user.name,
user.pic_path , employee.name ,employee.pic_path
FROM task
INNER JOIN employee ON employee.pno = task.employee_id
INNER JOIN user ON user.pno = task.user_id
INNER JOIN service ON service.service_id = task.service_id ";
SELECT user.name AS username, employee.name AS employeename
You get the point.
There are two steps:
You need to define a column alias for at least one of the two columns in the SQL statement:
SELECT t.employee_id,
t.user_id,
t.service_id,
u.name AS user_name,
u.pic_path,
e.name AS employee_name,
e.pic_path
FROM TASK t
JOIN EMPLOYEE e ON e.pno = t.employee_id
JOIN USER u ON ur.pno = t.user_id
JOIN SERVICE s ON s.service_id = t.service_id
Then you need to update the PHP logic to use the column aliases:
$empname = $data["employee_name"];
$username = $data["user_name"];
Yes so im building an query from the advanced search form.
I have this:
$query = "SELECT * FROM users WHERE 1 ";
$query .= "AND sex = '$sex' ";
for now, next im going to have AND birthday.. but then i dont know how to do it, because users birthday is stored in users_profile
So please correct me, how can i:
$query .= "AND birthday in users_profile = '1'";
Is this possible even, or should i reconstruct it and put birthday in users instead..
update:
in users, the id column there, is binded with users_profile´s uID.
So in users_profile´s uID column, there is the users id.
I assume your users_profile table is linked to the users table?
SELECT u.*, up.birthday
FROM users u
INNER JOIN users_profile up
ON u.user_id = up.user_id
WHERE sex = '$sex'
Here an Inner Join is used. The reason we can use u instead of users and up instead of users_profile is because we have set up the aliases "users u" and "users_profile up"
You need to look at the syntax for JOIN.
You need a way to join individual related rows in the two tables, something like:
SELECT u.* FROM users u, users_profile p
WHERE u.sex = 'M'
AND p.birthday = '1'
AND u.userid = p.userid;
I don't understand why you have separate tables for user and for users_profile, but you need to JOIN the two tables:
SELECT U.*
FROM users U
LEFT JOIN users_profile P
ON P.uID = U.uID
AND P.birthday = '1'
WHERE U.sex = '$sex'
Very possible, given you have the foreign key to the users_profile table.
Let's say the primary key in the users table is named 'id', and the users_profile table contain a field called 'uid' which point to the users table, you'd normally create the query like this:
SELECT * FROM users u, users_profile p WHERE u.id = p.uid
AND u.sex = '$sex' AND u.birthday = 1
