Question

I don’t know if it can be done with just a sql query or it needs a php code
when a cid is missing

There exist many missing values which I can’t handle manually

For example, here I don’t have cid=1 and cid=6.
I want to insert a row:

cid=1 tcp_sport='undefined' tcp_dport='undefined'

and

cid=6 tcp_sport='undefined' tcp_dport='undefined'

It seems to me I should create a procedure and insert between lines

another solution that I thaught was that I will create a table with cid and undifined values with the respective order and then join this one with that one and this join should have for example ifnull(tcp_sport,”)

would you please help me?

You need to use PHP to automate this.

<?php

$link = mysql_connect("localhost", "mysql_user", "mysql_password");
mysql_select_db("database", $link);

while($i < max_value_cid)//replace max_value_cid by the numeric maximum value of cid (SELECT MAX(cid) as max FROM table)
{
   $result = mysql_query("SELECT * FROM `table` WHERE cid=".$i, $link);
   if(mysql_num_rows($result) == 0)
   mysql_query("INSERT INTO `table` VALUES ($i, NULL, NULL);", $link);
   $i++;
}
?>

Do test the query on a sample set before execution and remember to backup the entire table, just-in-case.
