I have two tables I am selecting from them 1 I want to get the user information and 2 I want to get all images belonging to the user . but the query does not retrieve the images but in query window I get them . Also in the script if I decide to select from the images table the images are displayed but when I do the joining stuff it does not work. I know there is something am not doing well . please any help will be appreciated
Bellow is the code
$query='SELECT
tish_clientinfo.lastname, tish_clientinfo.address,
tish_clientinfo.firstname,
tish_images.image_name
FROM tish_clientinfo
INNER JOIN tish_images
ON tish_clientinfo.user_id = tish_images.user_id
WHERE user_id= '. intval($_GET['user_id']);
$result = $con->prepare($query);
$result->execute();
May be the server got confused about user_id. Try this
$query='SELECT
tish_clientinfo.lastname, tish_clientinfo.address,
tish_clientinfo.firstname,
tish_images.image_name
FROM tish_clientinfo
INNER JOIN tish_images
ON tish_clientinfo.user_id = tish_images.user_id
WHERE tish_clientinfo.user_id= '. intval($_GET['user_id']);
You just having a little problem just after the where clause on the user_id specify the table just like I have done in the bellow answer
$query='SELECT
tish_clientinfo.lastname, tish_clientinfo.address,
tish_clientinfo.firstname,
tish_images.image_name
FROM tish_clientinfo
INNER JOIN tish_images
ON tish_clientinfo.user_id = tish_images.user_id
WHERE tish_clientinfo.user_id= '. intval($_GET['user_id']);
$result = $con->prepare($query);
$result->execute();

$read = "SELECT * FROM elmtree
WHERE id ='$getid' AND
INNER JOIN elmtree_users ON elmtree.userid = elmtree_users.id";
The above query will not pull the information from the database to publish to the website.
Im trying to pull the item from the database with the $getid but also join the item id with the userid who uploaded it. Then using a while loop to print out the item to screen.
Any help would be greatly appreciated.
The SQL syntax you show isn't correct. A join clause describes which tables will be available for the rest of the query; all tables you mention need to be part of the ‘FROM’ clause, so that is where the ‘JOIN’ also belongs.
SELECT *
FROM elmtree
INNER JOIN elmtree_users ON elmtree.userid = elmtree_users.id
WHERE id ='$getid'
Your SQL query was not correctly written. The AND is not used in joining tables and the WHERE statement should be after the JOIN.
Try the following:
$read = "SELECT * FROM elmtree INNER JOIN elmtree_users ON(elmtree.userid = elmtree_users.id) WHERE elmtree.id ='$getid'";
UPDATE
Could you try the following in your code (replacing $this->database with your database variable) and post the result:
if ($result = $conn->query($read)) {
while ($row = $result->fetch_assoc()) {
...
}
} else {
throw new Exception("Database Error [{$this->database->errno}] {$this->database->error}");
}
$read = "SELECT * FROM elmtree INNER JOIN elmtree_users ON(elmtree.userid = elmtree_users.id) WHERE elmtree.itemid ='$getid'
Big thanks to Omari Celestine to finding the answer to the problem!
I have a simple blog where I'm practicing some php and mysql. I'm trying to display the username of the post author (you know where it says posted by Author).
I have two tables blog_members and blog_posts which are related 1 to many so I got a memberID field into the blog_posts. I'm trying to get the username of the member who's the author of the post.
I was thinking to do a join or something but I can't figure this out.
Here's what I was trying to do but it's not working because I'm sure I'm not using it properly.
$query1 = "SELECT username from blog_members JOIN blog_posts ON memberID = memberID ";
$result1 = mysqli_query($link, $query1);
$row1 = mysqli_fetch_array($result1);
PS: I got it working one way by using SESSION to get the userID but that works only if the user is logged is which is not the case, I want to display the name in any case.
Thanks!
Use inner join this way
And with a proper sanitize use $your_user_id for match
$query1 = "SELECT username
from blog_members
INNER JOIN blog_posts ON blog_members.memberID = blog_posts.memberID
WHERE blog_posts.memberID = '" .$your_user_id . "';";
JOIN syntax is wrong in your query.
Use following query:
$query1 = "SELECT username from blog_members JOIN blog_posts ON blog_members.memberID = blog_posts.memberID ";
$result1 = mysqli_query($link, $query1);
$row1 = mysqli_fetch_array($result1);
Try something like this, usng INNER JOIN :
$query1 = "SELECT blog_members.username FROM blog_members INNER JOIN blog_posts ON blog_members.memberID = blog_posts.memberID ";
reference : http://www.w3schools.com/sql/sql_join.asp
Here is a solution using a simple WHERE condition (same performance Explicit vs implicit SQL joins) :
SELECT a.username FROM blog_members a, blog_posts b WHERE a.memberID = b.memberID

I'm using prepared statements and I need to "select" other table, apart from these two, to get data but I get this:
Fatal error: Call to a member function bind_param() on a non-object in C:\xampp\htdocs\views\user\referral.php on line 16
If I add in SELECT table1.* , table.* , "theothertable.*"
$stmt = $mysqli->prepare("SELECT friends.*, rc_usuario.* // or just *
FROM friends
INNER JOIN rc_usuario ON rc_usuario.id = friends.friendID
WHERE friends.userID = ?");
$stmt->bind_param('s', $connectedUserID);
This is working fine, I get what i need, but I also need to get data from another table and I can't make other select because i need it all in a while to print all the data together.
The question is, can I SELECT something like that from 2 tables and also get data from other table/s?
Thank YOU!
EDIT: Add the new statement:
if ($stmt = $mysqli->prepare("SELECT friends.*, members.*, account_type.*
FROM friends
INNER JOIN members ON members.id = friends.friendID
INNER JOIN account_type ON account_type.name = members.acc_type
WHERE friends.userID = ? AND members.acc_type = ?")) {
$stmt->bind_param('is', $connectedUserID, $connectedAcc_type);
$stmt->execute();
} else echo $mysqli->error;
You can join more tables by using another INNER JOIN, like as follows;
INNER JOIN rc_usuario ON rc_usuario.id = friends.friendID
INNER JOIN rc_another ON rc_another.col = friends.coljoin
Just make sure you select all the columns you want in the joined table.
It might also help to run your prepare statement in an if, like this;
if($stmt = $mysqli->prepare("SELECT ...")) { // ... where the rest of your query is
$stmt->bind_param('s', $connectedUserID);
$stmt->execute();
}
else {
echo $mysqli->error;
}
which will give you an idea of any problems with the SQL syntax.
Hope this helps.
I have a system where I getting images out of my database, but when it does that, there is 3x of the same images.
I have tried with different ways, DISTINCT and such, but I have no clue how I fix this.
Here is my query code:
<?php
$id = $_GET['id'];
$query = "SELECT DISTINCT * FROM billeder INNER JOIN album ON fk_album_ID = $id";
$result = mysqli_query($con, $query);
while($row = mysqli_fetch_assoc($result))
{
$thumb_src = 'billeder/thumb_'.$row['billeder_sti'];
$full_src = 'billeder/'.$row['billeder_sti'];
echo "
<div class='ikon'>
<a href='$full_src'>
<img src='$thumb_src' alt='' />
</a>
</div>
";
}
?>
Hope someone can help me on the way to fix this :)
Without being able to see your table structure I won't be able to give an exact answer but the likely reason is because your INNER JOIN is not setup correctly.
SELECT DISTINCT *
FROM billeder
INNER JOIN album
ON (billeder.fk_album_ID = album.pk_album_ID)
WHERE
billeder.fk_album_ID = $id
Something like the above would be the correct way to JOIN a table and using a WHERE clause to then limit the date received.
JOIN must be used with two tables columns. See example:
SELECT * FROM tableA a INNER JOIN tableB b ON a.id = b.a_id;
What you're trying to make is something like this:
"SELECT DISTINCT * FROM billeder INNER JOIN album ON
billeder.fk_album_ID = album.album_id WHERE billeder.id = $id"
You shouldn't pass an argument to the JOIN. The arguments must be used on the WHERE clause.
Hey guys need some more help
I have 3 tables USERS, PROFILEINTERESTS and INTERESTS
profile interests has the two foreign keys which link users and interests, they are just done by ID.
I have this so far
$statement = "SELECT
InterestID
FROM
`ProfileInterests`
WHERE
userID = '$profile'";
Now I want it so that it selects from Interests where what it gets from that query is the result.
So say that gives out 3 numbers
1
3
4
I want it to search the Interests table where ID is = to those...I just don't know how to physically write it in PHP...
Please help.
Using a JOIN:
Best option if you need values from the PROFILEINTERESTS table.
SELECT DISTINCT i.*
FROM INTERESTS i
JOIN PROFILEINTERESTS pi ON pi.interests_id = i.interests_id
WHERE pi.userid = $profileid
Using EXISTS:
SELECT i.*
FROM INTERESTS i
WHERE EXISTS (SELECT NULL
FROM PROFILEINTERESTS pi
WHERE pi.interests_id = i.interests_id
AND pi.userid = $profileid)
Using IN:
SELECT i.*
FROM INTERESTS i
WHERE i.interests_id IN (SELECT pi.interests_id
FROM PROFILEINTERESTS pi
WHERE pi.userid = $profileid)
You are on the right track, lets say you execute the query above using this PHP code:
$statement = mysql_query("SELECT InterestID FROM `ProfileInterests`
WHERE userID = '$profile'");
Then you can use a PHP loop to dynamically generate an SQL statement that will pull the desired IDs from a second table. So, for example, continuing the code above:
$SQL = "";
while ($statementLoop = mysql_fetch_assoc($statement)) {
//Note the extra space on the end of the query
$SQL .= "`id` = '{$statementLoop['InterestID']}' OR ";
}
//Trim the " OR " off the end of the query
$SQL = rtrim($SQL, " OR ");
//Now run the dynamic SQL, using the query generated above
$query = mysql_query("SELECT * FROM `table2` WHERE {$SQL}")
I haven't tested the code, but it should work. So, this code will generate SQL like this:
SELECT * FROM `table2` WHERE `id` = '1' OR `id` = '3' OR `id` = '4'
Hope that helps,

Most likely you want to join the tables
select
i.Name
from
ProfileInterests p
inner join
interests i
on
p.interestid = i.interestid
where
p.userid = 1
