I am trying to create a mysql script that will search for results while at the same time filtering out duplicates of a particular field, I did some research and the code I found came in the format of something like this:
SELECT * FROM sites s INNER JOIN (SELECT h.*, row_number() over (PARTITION by muleid) as seqnum from history h ) h WHERE acceptid=2;
But it came up with the 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 '(PARTITION by muleid) as seqnum from history h ) h WHERE acceptid=2' at line 1
Is there anyone that can help?

Here is an error I don't understand:
mysql> UPDATE gp
-> SET gp.gpid = gp.new_gpid
-> FROM (
-> SELECT gpid, ROW_NUMBER() OVER (ORDER BY [gpid]) AS new_gpid
-> FROM gp
-> ) gp;
ERROR 1064 (42000): 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 'FROM (
SELECT gpid, ROW_NUMBER() OVER (ORDER BY [gpid]) AS new_gpid
' at line 3
As far as I can tell nested SELECT in a FROM statement seems to be depreciated.
Am using mysql 8.0.21
Any help to make this query work would be greatly appreciated.
Thank you
EDIT 1:
What I am trying to achieve is to update the gpid column with row numbers instead of the actual AUTO_INCREMENT id, which contains gaps in between ids, the explanation in this post Change mysql auto increment id column value
The UPDATE... FROM ... syntax is not supported by MySql.
You can do it with a JOIN:
UPDATE gp
INNER JOIN (
SELECT gpid, ROW_NUMBER() OVER (ORDER BY gpid) AS new_gpid
FROM gp
) t ON t.gpid = gp.gpid
SET gp.gpid = t.new_gpid;
See a simplified demo.
Your nested query is selecting from 'gp' but is then aliased as 'gp' it can't select from itself.

anyone can help me to find out from where I can solve this problem?
thank you all,
The problem is in the statement AND i.type_id IN ().
IN() function cannot get an empty value. You should check the php code that creates the query and add a validation to the variable to add the statement only if it not empty.
i have error on sql statment

You have an obvious syntax error using wherer instead of where.
wherer pr.process_id=th2.process_id and
Should be
where pr.process_id=th2.process_id and
When MySQL reports an error similar to Check the manual for the correct syntax to use near..., look exactly to that location or to the character immediately before it for your syntax error.
check the manual that corresponds to your MySQL server version for the right syntax to use near 'wherer pr.process_id=tem.p2
I am attempting to execute the following query:
$query = "SELECT O. * AS NUM FROM (ab_order O)
LEFT JOIN ab_user U ON (O.id_user=U.id)
WHERE O.id IN ( SELECT OT.id_ab_order FROM ab_order_transaction OT

$queryDB = $DB->queryExec($query);
On the live server:
it works with MySql version 3.3.10.
PHP version 5.2.17.
But I need to use localhost:
XAMPP for linux, v. 1.7.7
PHP 5.3.8
MySql version 5.5.16.
On localhost it says:
MySQL 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 'AS NUM
FROM (ab_order O)
LEFT JOIN ab_u' at line 1.
Is any easier way then uprgrade the live server Mysql database?
The aliasing of all the columns seems incorrect: SELECT O. * AS NUM. I'm unsure of why it would work on previous versions, but the as num should either be removed, or each column should be explicitly aliased.
You can define Alias for individual column in SELECT. Here is the issue
SELECT O. * AS NUM
Instead of this use
SELECT O. *
This is useful article Using Column Alias in SELECT Statement
Like this:
SELECT s.*, count( logs.* ) as ssh_count
FROM servers s
LEFT JOIN logs ON s.ip_address = logs.server_ip
But I get an error with that query:
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 '* ) as ssh_count FROM servers s LEFT JOIN logs ON s.ip_address = logs.server_ip LIMIT' at line 1
I think that's because you can't address a table in the count function.
I can do this using a subquery, but that will likely slowly down the query.
What is a better way of doing this?
You can adress a table column, but you can't address table.*, you can do this for example:
SELECT s.*, count( logs.server_ip ) as ssh_count
FROM servers s
LEFT JOIN logs ON s.ip_address = logs.server_ip
