March 24th, 2008, 03:10 AM
HI I am getting a syntax error. is there somthing worng or missing in my code?? here is the code
$c1="UPDATE Images SET on ='1' WHERE file ='$rm1';";
//query on top and bottom is mysql command to do the query.
$r1 = $db->query($c1);
the error says that I have an syntax error by on ='1' WHERE file ='$rm1';";
I have looked at the mysql website and it says it needs to be like this
$query="UPDATE table SET colum='1' WHERE username='bob';";

If on is a integer field I am not sure you should have it quoted.

I know on postgres you can put quotes around everything and it works.
I haven't used MySQL in a while and it most likely doesn't like the quotes.
Also, if you are trying to get the value out of $rml should it be something like this
Concatenate the sql string with the value of rml
$c1="UPDATE Images SET on ='1' WHERE file ='".$rm1."';";
I haven't used PHP in a bit, but in most languages putting a variable name in quotes just gives you a string literal. You would literally be getting $rml instead of the value stored in it.
Hope that helps.

well I tried what you guys said and I still get a syntax error.
here is what I exactly get as an 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 'on ='1' WHERE file =/home/linuxuser/WebPages/domainname.com/files/images/12063055' at line 1
I looked at the mysql page and still I can't find anything that might be wrong.

Well, it seems like from the MySQL error message that the file path string isn't quoted and the 1 is... did you really try removing quotes from the integer and made sure you've got your filename quoted?

'on' is a mysql keyword - as in 'left join x on..', so it doesn't make sense. If you have a column called 'on' and you can't change it, try wrapping in backticks `on`
