I’m definitely glad to know that this blog post back from 2006 helped you achieve the state of life you seem to like/enjoy Sharing this feedback was very kind of you – thanks!

Yes, I’m fine, too. I had somewhat departed from [professional] web-development, including Drupal… I’m moving towards higher involvement into various data analysis projects. Right now I’m a “microbial bioinformatician”

Within the next few weeks I’ll need to develop a web-interface to one of the tools I’ve developed, but since my favourite language is Python, I’ll most probably do that using Django. It will be interesting to see how different Django and Drupal are from the developer’s viewpoint…

Best wishes,
Bogdan

Here’s an example of the proper use of db_query (with 2 substitution variables):

  $query = "SELECT nid, title, created FROM " .
    "{node} WHERE created >= '%d' " .
    " AND created < = '%d'";
  $query_result =  db_query($query, $start_time, $end_time);

For SELECT, we could then proceed with e.g.

while ($links = db_fetch_object($query_result)) {
  // $content .=  $links;
}

Still working on the script.

I was able to figure out the solution to my previous problem, since I created another connection to the drupal database outside the function I had to declare the global database link in the function. I added this in all areas that the global d_sequences was declared.

$d_sequences = $GLOBALS["d_sequences"];
$link_drupal = $GLOBALS["link_drupal"];

I am now able to get the max id at least for users, but I think this should work for the other areas of the code too.

The second problem that I’m running into is copying the Nuke users and moving them to the Drupal database. Initially in the script this was done with a single INSERT … SELECT query. This is doable in the script if you have the same username and password for both databases. This was not going to work with me however. I decided then to divide the query into two sections.

First to execute the SELECT query on the Nuke database. Then loop through the results and INSERT them individually into the drupal database.

Here is that section of the code, and this is all I have so far.

$maxuid = get_max_id("users_uid");
message("Transferring User Details to Drupal.");
$query = "SELECT user_id, username, user_password, user_email, user_regdate, user_lastvisit, user_email";
$query .= " FROM $n_users";
$query .= " WHERE 1=1";
for ($i = 0; $i < count($user_array); $i++) {
	$query .= " AND username != '$user_array[$i]' ";
}
message("$query");
$result = mysql_query($query, $link);
while ( $row = mysql_fetch_array($result, MYSQL_NUM) ) {
	//set user id
	$u_id = $row[0]+$maxuid+1;
	$date_c = strtotime($row[4]);
	//$date_created = UNIX_TIMESTAMP(STR_TO_DATE($row[4], '%b %d, %Y'));
	$query = "INSERT into $d_users(uid, name, pass, mail, created, access, status, init, data) ";
	$query .= "VALUES ($u_id, '$row[1]', '$row[2]', '$row[3]', $date_c, '$row[5]', 1, '$row[6]', '$role_string') ";
	message(" $query ");
	$result = mysql_query($query, $link_drupal);
	if ($result) {
		// ...
	}
	else {
		failure("Users could not be added.");
		echo "Query used: $query ; \n";
		echo "Error returned by MySQL: (" . mysql_errno() . ") " . mysql_error() . " \n";
		exit();
	}
}

Your problem is similar to what is discussed in comments 65-68 on this page. This shouldn’t be happening for Drupal 5. However, you could try using my suggestions in comments 65-68 (from comment 68, for users, you would only need to set sequences.users_uid to whatever is the maximum or maximum+1 of the users table).

Thats exactly the approach i made. I was easily able to find all insert and update queries to adjust to the drupal database. Where do I post my final working version?

I think I’ve done all I could now I’m still stuck at the beginning and I’m not sure why.

Here’s what the script has done and the error I recieved.

Giving blank user names a default value (their login)
UPDATE d*******1.nuke_users set name=username where name=”
Default values set..(1 rows affected)
MySQL Error: Max ID for users_uid could not be retrieved
Back To Main?
Query used to get the Max ID: SELECT id FROM d*******7.sequences WHERE name=’users_uid’ ; Error returned by MySQL: (0)

I’ve placed the *** for the database names for safety.

Here is the code I’ve changed in the get_max_id function:


function get_max_id($field)
{
//message("Getting Max ID for $field");
$d_sequences = $GLOBALS["d_sequences"];
$query = "SELECT id FROM $d_sequences WHERE name='$field'";
$result = mysql_query($query, $link_drupal);
if ($row = mysql_fetch_object($result))
{
//success("Max ID for $field retrieved!");
return($row->id);
}
else
{
failure("MySQL Error: Max ID for $field could not be retrieved");
echo " Query used to get the Max ID: $query ; \n";
echo " Error returned by MySQL: (" . mysql_errno() . ") " . mysql_error() . " \n";
exit();
}
}


As you can see i’ve changed the $link to $link_drupal.

First, in addition to these:

$host = “localhost”; //Host address for MySQL
$username = “root”; //Username to connect to MySQL
$password = “”; //Password to connect to MySQL

add something like

$host_drupal = “localhost”; //Host address for Drupal MySQL
$username_drupal = “root”; //Username to connect to Drupal MySQL
$password_drupal = “”; //Password to connect to Drupal MySQL

It might be nice to rename $host and company into $host_nuke, …

Then, around lines 268-282, modify the code to connect to 2 databases, and store an extra database link in e.g. $link_drupal variable.

After that, you will have to look for each and every MySQL $query to modify it, so that is uses either $link[_nuke] or $link_drupal.

I’m not doing that myself, as I am currently very badly pressed for time, and wouldn’t be able to test the modified version anyway. However, feel free to ask if you encounter any problems while modifying the script.

Also, please do not forget to share your final working version.

I’m making my first migration from Nuke 7.5 to drupal 5 and hopefully next to 6 from there.

I love the migrate script and it seems to be very handy. My main object is to move the users and articles/stories.

The problem I’m having is with the database connections. Your script assumes that there is only one MySql host username and password for both nuke and drupal. However my domain host has my drupal and nuke databases with different user names and passwords. I attempted to add the same users and passwords in each but when I create new users I’m not given permission to specify the username and when I attempt to change the password I get massive errors.

The script is able to connect to the nuke database but the drupal database being seperate is the issue.

My next option is to change the migrate code to reflect the two different databases and their respective usernames. I think I have a general idea just by reading the code but if you can instruct me as to what areas need to have what changed so I don’t miss anything it would be greatly appreciated.

Thank You.

I’m not sure if you have to pre-populate the table with some values, but it won’t hurt if you do – just set all the values to whatever is the maximum of the mentioned ID.

To modify the script, you will only need to know this:
http://drupal.org/node/114774#db_last_insert_id

It is clear that set_max_id() function is now obsolete, and get_max_id() will have to be modified (I believe one could either call Drupal’s db_last_insert_id(), or just SELECT the ID column, ORDERED BY ID DESC).

Alternatively, you can manually create the “sequences” table in your Drupal 6 database (preserving the structure it had in Drupal 5), run the import (if there are no other errors), then just delete the sequences table you created.

no new version. If you are willing to create such a version, I’ll do my best to help you. Also, if you could come up with the list of changes necessary to make the current script work for nuke7-2-drupal6 conversion, I might modify the script appropriately for you to test.
