Question

Here is my query:

query2 = "
INSERT INTO randomnusers 
  SELECT src_ip, vlan_id, video_id, area 
  from video_2 
  WHERE date_pl >= '2011-11-29 00:00' AND date_pl <= '2011-12-05 23:55' 
  as table1 right join (SELECT distinct src_ip, vlan_id 
                        from video_2 
                        WHERE date_pl >= '2011-11-29 00:00' 
                          AND date_pl <= '2011-12-05 23:55' 
                        order by rand() limit 50) 
  as table2 on table1.src_ip = table2.src_ip, table1.vlan_id = table2.vlan_id"

In video_2 table, each users (use the combination of src_ip and vlan_id to identify different users) have several entries about their downloading history.

Now I want to randomly choose 50 different users, list all their downloading history in a new table called randomnusers.

But this syntax has an error around “as table1” can anyone help me to check?

Many thanks

The syntax of SELECT statement is SELECT t1.name, t2.salary FROM employee AS t1, info AS t2 WHERE t1.name = t2.name;

query2 = "INSERT INTO randomnusers (
    SELECT src_ip, vlan_id, video_id, area 
    from video_2  AS table1

    right join (SELECT distinct src_ip, vlan_id 
                    from video_2 
                    WHERE date_pl >= '2011-11-29 00:00' 
                      AND date_pl <= '2011-12-05 23:55' 
                    order by rand() limit 50) 
        as table2 on table1.src_ip = table2.src_ip AND table1.vlan_id = table2.vlan_id
    WHERE date_pl >= '2011-11-29 00:00' AND date_pl <= '2011-12-05 23:55')"
