It throws an error:

If I remove the LIMIT 1, it works, but I want it on for security measures.
As I see it, the LIMIT is only valid for single table deletions
http://dev.mysql.com/doc/refman/5.0/en/delete.html
For the multiple-table syntax, DELETE deletes from each tbl_name the rows that satisfy the conditions. In this case, ORDER BY and LIMIT cannot be used.
LIMIT cannot be used on a multi-table delete. See the DELETE syntax documentation.

I am trying to Update Some row in my database. If I run without limit its working fine but if I run it with limit its giving me error like below
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 '35' at line 1
My Query is like below
UPDATE number_list SET sync = 0 WHERE server = 1 ORDER by id ASC LIMIT 0,35
Let me know if someone can correct me.
You can use limit in an update (in MySQL) but not an offset. So just do:
UPDATE number_list
SET sync = 0
WHERE server = 1
ORDER by id ASC
LIMIT 35;
This is a bit subtle, because SELECT supports offsets. However, it is clear in the syntax diagram for UPDATE.
I try this query
INSERT INTO shop.product(prod_id,model,desc) SELECT product.id_prod,prod_lang.name,product.ref from product left join product_lang on product_lang.id_prod = product.id_prod
However I got this error
SQL execution error # 1065.Response from the database:

Two problems:
DESC is a reserved keyword. Use backquote (``) for desc.
Change prod_lang to product_lang in the query.
Solution:
INSERT INTO shop.product (prod_id,model,`desc`)
SELECT product.id_prod,product_lang.name,product.ref
from product left join
product_lang on product_lang.id_prod = product.id_prod
Note:
It is a good practice to use backquotes for all columns eventhough it is not a reserved keyword.
I have such sql-query:
DELETE `LINK_LA_TYP`
FROM
`LINK_LA_TYP`
JOIN `LINK_ART` ON `LINK_LA_TYP`.LAT_LA_ID = `LINK_ART`.LA_ID
JOIN `ARTICLES` ON `LINK_ART`.LA_ART_ID = `ARTICLES`.ART_ID
WHERE
(
`ARTICLES`.ART_SUP_ID IN(
10008,
10439,
11005,
...
...
441
)
)
LIMIT 50000;
But i get error.... From mysql-doc i get that with delete+join+limit i will get errors....
But how can i change my code? (new to mysql and sql in all). How to change my code? To limit rows to delete....
Also in phpmyadmin i get

From the docs For the multiple-table syntax, DELETE deletes from each tbl_name the rows that satisfy the conditions. In this case, ORDER BY and LIMIT cannot be used. dev.mysql.com/doc/refman/5.0/en/delete.html – Michael Berkowski 2 mins ago
I concur with this. Additionally,
The DELETE command cannot have a LIMIT clause. Also, generally speaking you cannot DELETE from multiple JOINed tables.
It MIGHT be possible to rewrite the statement using a subselect something like:
delete from LINK_LA_TYP
where LAT_LA_ID in
(select LA_ID
from LINK_ART
join ARTICLES on ARTICLES.ART_ID = LINK_ART.LA_ART_ID
where ARTICLES.ART_SUP_ID in (...));
Im looking to add all products that dont have attribute_id = 12 into oc_product_attribute,
But getting a syntax 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 '12) select ocp.product_id from oc_product ocp where ocp.product_id not in (SE' at line 1
insert into `oc_product_attribute` (ocp.product_id, 12)
select ocp.product_id from oc_product ocp where ocp.product_id not in (SELECT oca.`product_id`
FROM `oc_product_attribute` oca where oca.attribute_id = 12)
Am I missing something here, quite new to SQL.
Usually you have to enumerate columns in insert statements.
insert into `oc_product_attribute` (ocp.product_id, 12)
must be
insert into `oc_product_attribute` (ocp.product_id, some_column_name)
and I guess it may be attribute_id.

I tried this with MySQL:
DELETE FROM `contact_hostcommands_relation` AS `ContactHostCommand` WHERE (`ContactHostCommand`.`chr_id` = 999999) LIMIT 1
And I get this:
#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 'WHERE (`ContactHostCommand`.`chr_id` = 999999) LIMIT 1' at line 1
Note: This query is automatically generated and conditions are based on table aliases.
Why I get this error?
Is there any way to use table aliases in where clause?
Is this MySQL specific?
What #Matus and #CeesTimmerman said about MSSQL, works in MySQL 5.1.73 too:
delete <alias> from <table> <alias> where <alias>.<field>...
You can use SQL like this:
DELETE FROM ContactHostCommand
USING `contact_hostcommands_relation` AS ContactHostCommand
WHERE (ContactHostCommand.`chr_id` = 999999)
LIMIT 1
You cannot use AS in a DELETE clause with MySQL :
DELETE FROM `contact_hostcommands_relation` WHERE (`chr_id` = 999999) LIMIT 1
