Can't find my Query syntax error

[brainintraining]

Maybe my eyes are just tired...
Can anyone help me spot the syntax error in this code:
[PHP]$sql = "INSERT INTO `images` ( 'imgid' , 'lstid' , 'descrip' )
VALUES (
'', '" ."$pid". "', ''
);";


$result = @mysql_query("$ sql") or die(mysql_error ());[/PHP]

I get the error:

You have an error in your SQL syntax near ''imgid' , 'lstid' , 'descrip' ) VALUES ( '', '15', '' )' at line 1

thanks in advance for your help!!!

Use backticks (`) for column names and single quotes (') for values:

[code=php]
$sql = "INSERT INTO `images` (`descrip`) VALUES ('$pid')";

if(! ($result = mysql_query($sq l)))
throw new Exception(mysql _error());
[/code]

Couple of minor things:

• If a value will be null, you don't have to include it in the list of fields.
• You're not supposed to end your queries with a semi-colon when you pass them to mysql_query. Don't believe me? http://php.net/mysql_query. Look under "query".
