If It Exists

Quick one guys.

 

I'm running an INSERT INTO script and what I'm trying to do is get it to check if what it's trying to insert is already present in my database and therefore skip it.

 

mysql_query("INSERT INTO names ( firstname ) VALUES ( 'Bob')") or die(mysql_error());

 

Running a for loop and basically, if Bob is already present in database under the firstname column, sjip it - how do i put that into the WHERE clause.

 

Many thanks and happy hols

Or, use INSERT.... ON DUPLICATE.

 

$sql = "
  INSERT INTO names (firstname)
  VALUES ('Bob')
  ON DUPLICATE KEY UPDATE firstname = 'Bob';
";

 

The 'firstname' field would still however need to have a unique constraint. See here for more details.
