copying and inserting related records into 2nd table? error...

Recommended Posts

hi people

i'm trying to copy all the records that is related to my search.
my first table is 'topics',
and the 2nd table is 'topics_tmp'.

and the codes that producing an error is here below,
[code]
//Empty temporary table topics_tmp then fill again with contents from topic_rel[]
for($x=0; $x<=$total_rec; $x++){
//select records from table TOPICS first
$query  = "SELECT * FROM topics WHERE id='$topic_rel[$x]'";
$result = mysql_query($query) or die('Error, query failed');
$row = mysql_fetch_array($result, MYSQL_ASSOC);
$id_tmp = $row['id'];
$title_tmp = $row['title'];
$descrip_tmp = $row['description'];
$url_tmp = $row['url'];

//then insert selected data into TOPICS_TMP temporary table
$query = "INSERT INTO topics_tmp (id, title, description, url) VALUES ('$id_tmp', '$title_tmp', '$descrip_tmp', '$url_tmp')";
mysql_query($query) or die('Error, insert query failed');

}
[/code]

when i execute it the error message is showing up -->'Error, insert query failed'.
now what was my mistake here? am i doing the right copying from 1st table
and inserting the records into 2nd table?
Or do i have syntax error here?

Thank you very much in advance... for your kind help.
