MYSQL copy row to another identical table with AUTO_INCREMENT id field - mysql

Question

I have a movie database where movies are inserted into a table named titles with an AUTO_INCREMENT primary key named titles_id. Users can submit movies anonymously which are inserted into a separate identical table named titles_anon. After reviewing entries in titles_anon I want to insert them into titles but the id column is causing problems
I tried this:
INSERT INTO titles SELECT * FROM titles_anon WHERE
title_id='$title_id';
I either get a duplicate key error, or if the title_id does not already exist in titles it inserts OK but uses the titles_anon id instead of a new AUTO_INCREMENT value which I want.
How do I copy a row between tables when both tables have an AUTO_INCREMENT primary key?

Answer 1

INSERT INTO titles
(column_name1, column_name2, column_name3, column_name4,...)
SELECT title_id, col2, col3, col4,..
FROM titles_anon
WHERE title_id = '$title_id';

Answer 2

You define your fields in SELECT, but omit the PK and add the same fields to INSERT!

Answer 3

You can omit the id column completely, let mysql generate it for you. This need a little longer SQL to specify the exact columns you want to insert.
INSERT INTO titles (columns-other-than-the-primary-key)
SELECT columns-of-the-same-order FROM titles_anon

Answer 4

In PHP you can do something similar to:
$rs = mysql_query("select * from table_orig where RowID=$IDToCopy",$db_conn);
$row = mysql_fetch_assoc($rs);
$sql = '';
$fields = '';
foreach($row as $k => $v){
if($k == "RowID") continue;
$sql .= ",'$v'";
$fields .= ",$k";
}
$sql = "insert into table_copy (".substr($fields,1).") values (".substr($sql,1).")";
mysql_query($sql,$db_conn);

/* copy table with primary key to another table */
$table_old='colaboradores'; // your table old
$table_new='colaboradores2'; //your table new
// sql all columns withou primary key (column_key <> 'pri'
$rs=mysql_query("select column_name from INFORMATION_SCHEMA.COLUMNS
where table_name = '$table_old' and column_key <> 'pri' AND
table_schema = 'your database'");
// get all columns
$rows = mysql_fetch_assoc($rs);
$fields = '';
// mount fields in line
foreach ($rows as $k => $v) {
$fields .= ",$v[0]";
}
// remove first comma
$fields = substr($fields,1);
echo "Sintaxe for Create table in Mysql";
echo "CREATE TABLE $table_new SELECT $fields FROM $table_old ";
echo "Sintaxe for Insert from old table to new table Mysql";
echo "INSERT INTO $table_new $fields SELECT $fields FROM $table_old";
