MySQL schedule update syintax wrong? - mysql

I'm trying to set a trigger in my MySQL database, so I'm using below query:
CREATE EVENT pwdupdate
ON SCHEDULE EVERY 3 MINUTE
DO
UPDATE 'passwords'
SET 'pass'= SUBSTRING((RAND())
Basically I want it to update the pass field of a table with a random string, but it keeps telling me that there's a syintax 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 ''passwords' SET 'pass'= SUBSTRING((RAND())' at line 5
Any help ?
EDIT : I removed the single quotes as suggested, but still the error remains

You do not need single quotes for table and column name and its invalid in mysql however you can use backticks ``
UPDATE passwords
SET pass= substring(RAND(),8)

Request Update phpMyadmin

I want Update an SQL tablein phpMyAdmin, to change a values of a column.
My request is:
Update article set Id_LRU where ID_Article='DIEPRESTATION'
It return an error:

Update article set Id_LRU where ID_Article like 'DIEPRESTATION'
Also it got the same error.
How can I correct it please .
You have syntax error.
Update article set Id_LRU ='YOURVALUE' where ID_Article like 'DIEPRESTATION'
Try above query.

Syntacts error in mysql query

Someone gave me this query to delete community from a database on my server using phpMyAdmin, it worked when he use it so I asked him to send it to me, but I get a error
MySQL said:
Documentation
#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 * FROM `connections` WHERE 1" :
delete from connections where communit' at line 1
I did a search on the error but could not figure it out.
"SELECT * FROM `connections` WHERE 1" :
delete from connections where community="XYZ"
You should separate your queries with ; and not :
The error you are receiving as you've shown it is because this line is incorrect:
SELECT * FROM `connections` WHERE 1"
First because it's ending in an unnecessary double quotation mark. MySQL does not use double quotes but single quotes, and even still the other single quote is not there to match it.
The single quotes are also a problem for community="XYZ", this should read: community = 'XYZ'
Secondly, you don't have a condition for your where statement, you must be missing something like:
WHERE columnName = 1;
If you were trying to select everything from connections, you can just remove that where clause all together.
EDIT
In addition, MySQL queries are separated by a semi-colon, not a colon, so MySQL will not realize you are trying two different queries.

Error while updating inMySQL

I am working with MySQL and I am facing issues while updating the below command:
UPDATE group_access_mst SET
access='0',view='0',add='0',modify='0',delete='0',save='0',xl='0',import='0' WHERE role_id='1' AND page_id='1';
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 'add='0',modify='0',delete='0',save='0',xl='0',import='0' WHERE
role_id='1' AND p' at line 1
If I remove add,delete from the quesry it works fine!!
Is there any way i can make these command to work. I can understand that in MySQL ADD,DELETE,SELECT,INSERT are commands so it is not working.
In this case i need to change the fields names?
You should enclose the field names within back quote:
UPDATE group_access_mst
SET `access`='0',
`view`='0',
`add`='0',
`modify`='0',
`delete`='0',
`save`='0',
`xl`='0',
`import`='0'
WHERE role_id='1'
AND page_id='1';

MySQL Syntax with DELETE FROM?

I have this bit of SQL that always returns an error, though I can't find why it is returning the error. I have connected to the database with no errors. I'm running PHP 5.2.17, MySQL 5.5.25a, and Apache 2.4.2.
The SQL:
DELETE FROM mail WHERE to=1
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 'to=1' at line 1
TO is a reserved word, you need to use backticks:
DELETE FROM mail WHERE `to` = 1
By adding backticks on the column name escapes in from MySQL Reserved Word
DELETE FROM mail WHERE `to`=1
if the column to is not e.g. INT or DEC you should make it to = "1"

MySQL query sanity check, for update query

I have this query
update user_remember_me set
when='2012-07-06 05:44:27',
hash='c8e9d2c0dd156b5c68d0b048e5daa948e6b8fac7'
where user = '21';
and I am getting this error
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 'when='2012-07-06 05:44:27', hash='c8e9d2c0dd156b5c68d0b048e5daa948e6b8fac7' wher' at line 1
Im failing to miss the connection here, I've used simple updates like this everywhere without issue til this, maybe Im getting to tired, but this is gonna drive me nuts til I have an answer
When is a key word in mysql, change the column name
or you can use it as
`when`='2012-07-06 05:44:27'
when is a reserved word in mysql
update user_remember_me set
`when`='2012-07-06 05:44:27',
`hash`='c8e9d2c0dd156b5c68d0b048e5daa948e6b8fac7'
where user = '21';
So you must backtick your column
when is a keyword within MySQL. You have to escape it, if you want to use it as a column identifier (as you should with all column identifiers!):
UPDATE user_remember_me
SET
`when`='2012-07-06 05:44:27',
`hash`='c8e9d2c0dd156b5c68d0b048e5daa948e6b8fac7'
WHERE `user` = '21';
