Question

This query works:

$con = mysql_connect("localhost","root","pw");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("db", $con);

$sql="INSERT INTO l1_clubmsg (msg, subject, status)
VALUES
(1,1,1)";

if (!mysql_query($sql,$con))
  {
  die('Error: ' . mysql_error());
  }
echo "1 record added";

mysql_close($con);

But when i change:

$sql="INSERT INTO l1_clubmsg (msg, subject, status)
VALUES
(1,1,1)";

To:

$sql="INSERT INTO l1_clubmsg (msg, subject, status, to)
VALUES
(1,1,1,1)";

I get 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 'to) VALUES (1,1,1,1)' at line 1

The ‘to’ column does exist in l1_clubmsg

Any ideas why this gets an error? thanks

Answer 1

It not because of 4 or more columns that the error is produced.

The error is produced because to is a keyword and can’t be used like this.

You can write the query as:

$sql="INSERT INTO l1_clubmsg (msg, subject, status, `to`)
VALUES
(1,1,1,1)";

For the list of keywords you could look here

Note: Normally try to avoid keywords in the query. And if you use make sure that you escape it using backticks(`)
