Wrong syntax (MySQL, PHP) - php

This line of code
$SQL = "SELECT * FROM stats ORDER BY Team WHERE Team='$teamval'";
is returning with the following MySQL error:
You have an error in your SQL syntax; check the manual that corresponds to
your MySQL server version for the right syntax to use near 'WHERE Team='OTT''
at line 1
I can't find anything wrong with the syntax, what's wrong with it?

The ORDER BY clause must appear after the WHERE clause. So, your query should, instead, be:
SELECT * FROM stats WHERE Team='$teamval' ORDER BY Team

You have used in correct syntax of using order by before where clause , ORDER BY should be used at the end of query if you have used limit in your query then put order by before limit
SELECT * FROM stats WHERE Team='$teamval' ORDER BY Team

Replace:
$SQL="SELECT * FROM stats WHERE Team='$teamval' ORDER BY Team";

Use of CONCAT in FROM clause

I have a non-working query as the sub-query FROM clause doesn't understand CONCAT():
SELECT *
FROM `events` e
WHERE EXISTS (SELECT *
FROM CONCAT('prefix_', e.`event_id`) registrations
WHERE registrations.`attendee` = 123456
)
Is there any way to make this work in a single-statement?
The error message I receive is:
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '('prefix_', e.event_id) registrations
You are trying to dynamically come up with a table name? I don't think this is possible...because doesn't the FROM clause table name need to be resolved prior to the SQL being able to be evaluated and executed?
SELECT * FROM (SELECT *,
CONCAT('prefix_', `event_id`) as prefix FROM `events`
WHERE events.attendee = 123456
);

ORDER BY FIELD does not work with php

I need the MySQL parameter ORDER BY FIELD to order threads from a forum.
Here the exact SQL command: $ids is "19,3,12,256,1023"
SELECT*
FROM
Threads
WHERE
ID IN ($ids)
LIMIT
$untere_schranke, 50
ORDER BY FIELD(ID,$ids)
In phpMyAdmin it works fine but when I use php i get this:
You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use
near 'ORDER BY FIELD(ID, 19,3,12,256,1023)' at line 15
Order by statement should be before the limit
order by FIELD(ID,$ids)
LIMIT
$untere_schranke, 50

MySqli and PHP: Not in statement

I'm trying to get data by an mysqli query.
Query looks like:
SELECT * FROM pxldr_drawings
ORDER BY RAND()
WHERE id NOT IN (1,3,4,2)
LIMIT 1
But i get the following error message
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE id NOT IN (1,3,4,2) LIMIT 1' at line 3
I also tried NOT IN ('1','3','4','2') and NOT IN(1,3,4,2), but neither worked.
Thanks, LB
WHERE clause must be before ORDER BY clause.
try this
SELECT * FROM pxldr_drawings
WHERE id NOT IN (1,3,4,2)
ORDER BY RAND()
LIMIT 1
The order of clauses is important, order by should come after where.
SELECT * FROM pxldr_drawings
WHERE id NOT IN (1,3,4,2)
ORDER BY RAND()
LIMIT 1
For the proper syntax of where different clauses need to be placed, please refer to "Select Syntax" documentation.

SQL/PHP query error

I have the following error:
1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'select manufacturers_id, manufacturers_name, manufacturers_image, date_added, la' at line 1
The query:
SELECT COUNT(
SELECT manufacturers_id,
manufacturers_name,
manufacturers_image,
date_added,
last_modified
FROM manufacturers
ORDER BY manufacturers_name
) AS total
This happens also to some other categories in my website. All finish their line incomplete.
This query would do what you want:
SELECT COUNT(*) AS total
FROM manufacturers
What's wrong with your query:
COUNT() accepts an expression or single column as parameter - you're passing multiple
ORDER BY doesn't make much sense as soon as what you need is just number of rows (for obvious reason that number doesn't depend on order)
Maybe because the code is not on here full but what I can see is the mysql/mysqli_query is missing, and the ";" at the end of the code.

Error when using SQL_CALC_FOUND_ROWS()

I'm doing a simple MySQL query to count the number of rows a query is returning without the effect of the LIMIT clause. I'm using Active Records with Codeigniter PHP framework.
Problem: I'm getting an error when SQL_CALC_FOUND_ROWS is used. Why is this so?
Query
SELECT `listing_id`, SQL_CALC_FOUND_ROWS listing_id FROM (`listings`) LIMIT 100
Error
You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use
near 'SQL_CALC_FOUND_ROWS listing_id FROM (listings) LIMIT 100' at
line 1
Codeigniter Active Records
$this->db->select('listing_id')
->select('SQL_CALC_FOUND_ROWS listing_id', FALSE)
->from('listings')
->where('price < 1000')
->limit($limit, $offset)
->order_by('listing_id', 'desc');
SQL_CALC_FOUND_ROWS doesn't return a value, it's simply a modifier to indicate that the number of rows —where the LIMIT clause is not taken into account— should be saved so it can be retrieved later on, by using a second query (without generating the complete result set twice). Think of it the same as the DISTINCT keyword.
For more information, please read the documentation on this topic.
You can use MySql's count() function to achieve what you are looking for ie.
SELECT `listing_id`, count(*) FROM (`listings`) LIMIT 100
