Update a column on rows of which another column has multiple values - mysql

I am having trouble with something like this:
UPDATE `database` SET `col1` = 0 WHERE `col2` in (1,2,3,4);
Following is an actual failed query.
Error Message:
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 '#cc3.biz, sales#allservico.com)' at line 1
SQL:
UPDATE `CubeCart_customer` SET `optIn1st` = 0 WHERE `email` in (markscarts#cc3.biz, sales#allservico.com);
I have searched the web, and here, and tried several variations in my code to produce the query, but I just can't pinpoint where I'm failing.
Any light on this matter would be greatly appreciated.


You need quotes around your string values
UPDATE CubeCart_customer
SET optIn1st = 0
WHERE email in ('markscarts#cc3.biz', 'sales#allservico.com');

mysql syntax error for update rows

update amazon-crawler set `flag_images`= '0' where `id`='966'
i get #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 '-crawler set flag_images= '0' where id='966'' at line 1
why syntax error?
amazon-crawler is the table
flag images and id are columns

My guess is that the hyphen in the table name is causing problems, because it is an arithmetic operator. Try also escaping the table name:
UPDATE `amazon-crawler` SET `flag_images`= '0' WHERE `id` = '966';
Note that you should try to avoid using backticks in your query, unless absolutely needed. Using backticks means that any name would potentially work, even one which happens to be a MySQL reserved keyword. Also, I'm guessing that flag_images and id are numeric columns, in which case you should be comparing them against numbers, not strings. So I would write your update as this:
UPDATE `amazon-crawler` SET flag_images= 0 WHERE id = 966;
Here, only the table name has to appear in backticks.

Update longtext field in mysql

Im trying to update a longtext type field called 'comment' using a simple sql query in mysql client like this :
Update mytable set comment='Test' where id = 1;
But i'm getting this error
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 'comment='Test' where id = 1' at line 1
Am i missing something ?, thanks in advance.

comment is a reserved word, if you want to have a table/field with that name, you have to quote it (or use the table.fieldname syntax, in case of a field). default in mysql is the backtick for that, so:
update mytable set `comment`='Test' where id = 1;

Found it, it gets solved with this:
update mytable as a set a.comment='Test' where id = 1;

select inside insert with more data to be inserted

I'm facing a problem with select inside insert statements.
I've take a look at the questions similar to this but still the query is not working.
first, I'm working with MySQL version 5.6.24 with engine InnoDB, and I'm trying to insert this row:
INSERT INTO form (SELECT course_name FROM course WHERE course_id ='1' ), '123456','5','3','6','1','3','6','1','2','5','6','1','4','1','2','3','good','not bad','bad')
I want the first column to be retrieved (which is only one value), but not the other.
I've tried many syntax formats, with VALUES, with semicolon, with more parentheses, etc... but non work. Here is the 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 ' '123456','5','3','6','1','3','6','1','2','5','6','1','4','1','2','3','good','no' at line 1
Thanks.

Use an INSERT-SELECT:
INSERT INTO form
SELECT course_name, '123456','5','3','6','1','3','6','1','2','5','6','1','4','1','2','3','good','not bad','bad'
FROM course
WHERE course_id = '1'

MySQL query with enum values

I've the following structure in MySQL 5.6.19.
CREATE TABLE `metadata` (
`md5` char(32) NOT NULL,
`match` enum('none','md5','similarity') DEFAULT NULL
)
And I got an error doing a query like this:
select * from metadata where match = 'md5';
The error is:
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 '= 'md5'' at line 1
There're multiple entries in the table and rows that could match the query. But MySQL refuse to do it. Any idea about the reason?
Thanks!

MATCH is reserved keyword in MySQL: http://dev.mysql.com/doc/mysqld-version-reference/en/mysqld-version-reference-reservedwords-5-5.html. You should enclose your field name in backticks to make it work:
select * from metadata where `match` = 'md5';

what wrong with my mySQL query using REGEX and or operator?

I have a script that is generating queries like this one by grabbing categories and keywords from the database. However something is wrong with the syntax it seems. here is the code first:
UPDATE `mrhowtos_main`.`eng-jap` SET `category` = 'travel' WHERE `eng` REGEXP 'abroad|country|sight seeing|foreign|plane|train|bus' and where `category` REGEXP 'misc|none';
and here is the error returned by mySQL:
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 category REGEXP 'misc|none'' at line 1
I have looked at it for a long time and still dont seem to see what is wrong with it. im certain the error is not in the table or column names in the DB.

The second where shouldn't be there. Try:
UPDATE `mrhowtos_main`.`eng-jap` SET `category` = 'travel' WHERE `eng` REGEXP 'abroad|country|sight seeing|foreign|plane|train|bus' and `category` REGEXP 'misc|none';
