[SOLVED] Mysql Query not working

nate2099 · #1 Dec 30th, 2007, 08:27

Hi, this query:

mysql_query("UPDATE messages SET read_message = '1' WHERE key = '$value'") or die(mysql_error());

Throws this 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 'key = '4'' at line 1

The table definately exists, the field is set to int-1, and is the primary key. I've tried:

Code: Select all

WHERE key = $value

and also

Code: Select all

WHERE key = '$value'

and it always throws that same problem.

Thanks,

Nate.

Thanks for posting the solution

... I never knew that -- but I've never named a column key either lol

Sure you can name a column 'key'. Your problem is that 'key' is a keyword in MySQL.....

If "key" is a keyword in MySQL, that means you can't name you database column as "key"

OK, you're probably right....

I had the same problem with "id." Almoste tore all of my hair out before I figured that one out.....

You're right again.... I meant "index".....

haha.. ok!

I had some nightmare with "no" few years ago!
You can't name a database field as "no"
It's a reserved word!

There's quite a few apparently:

Yeah, "key" is in the list

Does MySQL and MSSQL have different reserved word?
"no" is a reserved word in MSSQL, and it's not in the list ^

alexgeek · #13 Jan 3rd, 2008, 01:41

I assume they have a few differences, it is a different language but most of the words are the same.

Found one here! [Reserved Word]
