Drupal DB : Have to move some data from one table to another by cheking the condition at remote server..!

Question

I am working with a portal, where there is content type. The front end developer who made this portal added a CCK field for file attachment & there is already File attachment field given by core. Now we won't go to discuss why did he do that as I also don't know.

Now I have to removed that CCK field & if I remove directly, I will loose all the data uploaded by this field as it will remove the table of it.

So now I am trying to replace the value from this CCK field table to default upload table & update the filepath in files table..so that it would come in view for attached files.

Because I am not very good at PHP or MySQL I am seeking some help from you guys..

Here is the basic code, which I have written...please suggest the correction & please tell me will I be able to connect remote server DB in doing it so -

<?php

mysql_connect("http://edlabs.in/connect:22","connect","");
mysql_select_db("connect");

for($i=0; $i<=1; $i++){

    $fid_cck = array(mysql_query("SELECT field_upload_doc_fid FROM content_field_upload_doc WHERE field_upload_doc_list > 0"));
    $fid_core = array(mysql_query("SELECT fid FROM upload"));

    foreach($fid_cck as $fid_cck_value){

        foreach($fid_core as $fid_core_value)
        {
            if($fid_cck_value != $fid_core_value){

                $file_name = mysql_query("SELECT filename FROM files WHERE fid = $fid_cck");
                $nid_cck = mysql_query("SELECT nid FROM field_upload_doc_fid WHERE fid = $fid_cck");
                $vid_cck = mysql_query("SELECT vid FROM field_upload_doc_fid WHERE fid = $fid_cck");

                mysql_query("INSERT INTO upload VALUES('$fid_cck', '$nid_cck', '$vid_cck', '$file_name', 1, 0)");

                $filepath = array(mysql_query("SELECT filepath FROM files WHERE fid = $fid_cck"));

                $new_filepath = str_replace("/background_docs", "", $filepath);

                mysql_query("UPDATE files SET filepath=$new_filepath WHERE fid = $fid_cck");

            }
        }
    }


}

I have solved this problem by following these steps-

1. Created a DB with the same name as my portal at my local phpmyadmin.
2. Exported three table named content_field_upload_doc, files & upload from DB of my portal.
3. Wrote a custom PHP code with some MySQL query to make query and find DIFF of those files which are in content_field_upload_doc but not in upload table & picked the name of that from table files.(I am giving the code below).
4. Ran the code on my wamp and echoed the INSERT query.
5. Copied all the query & executed that with SQL on my phpmyadmin at portal DB.
6. Copied all the files from previous used folder inside public folder & pasted that to default public folder.

7. Removed the CCK field from content type...and it's DONE..!

   die('Could not connect: ' . mysql_error()); } else{

   mysql_select_db("connect");
   
   $rs_fudl = mysql_query("SELECT vid, nid, field_upload_doc_fid FROM content_field_upload_doc WHERE field_upload_doc_list > '0'");
   while($rs_fudl_row = mysql_fetch_array($rs_fudl))
   {
   
       $fid_fudl = $rs_fudl_row['field_upload_doc_fid'];
   
       $rs_file = mysql_query("SELECT filename,filepath FROM files WHERE fid = '$fid_fudl'");
   
       //echo mysql_num_rows($rs_file)."<br />";
   
       while($rs_file_row = mysql_fetch_array($rs_file)){
   
               $rs_upload = mysql_query("SELECT * FROM upload where fid='".$fid_fudl."'");
   
               if ( mysql_num_rows($rs_upload) == 0) {
   
               /*  $new_filepath = str_replace("/background_docs", "", $rs_file_row['filepath']);
   
                   $filepath = $new_filepath;
               */
                   $filename = $rs_file_row['filename'];
                   $vid_fudl = $rs_fudl_row['vid'];
                   echo "<br />";
   
                   $nid_fudl = $rs_fudl_row['nid'];
                   echo "<br />";
   
                   echo "INSERT INTO upload VALUES ('$fid_fudl','$nid_fudl', '$vid_fudl', '$filename','1', '0');" ;
                   echo "<br />";
               //  echo "UPDATE files SET filepath= '$filepath' WHERE fid = '$fid_fudl';";     
   
               }
       }
   }
   mysql_close($con);
   

   } ?>
