insert into tables from another tables

Well, I trying insert into tables to another but I get this error;

WordPress database error: [You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ''lcl_user_agent' (user_agent, hitcount, click_timestap) SELECT visite_useragent,' at line 1]

This is my code;

$addagent = "INSERT INTO $wpdb->prefix.'lcl_user_agent' (user_agent, hitcount, click_timestap) SELECT visite_useragent, visite_hitcount, click_timestap FROM $wpdb->prefix.'lcl_visite_agent' .agent_id IN (' . $agent_id . ')";

$wpdb->query($addagent);

I want insert into lcl_user_agent the visites from visite_useragent then I get the visite for block with $agent_id from the form

Answer

It looks like you’re messing up at the very end. It should be this form:

INSERT INTO table2 (column1, column2, column3, ...)
SELECT column1, column2, column3, ...
FROM table1
WHERE condition;

So maybe this is what you’re going for?

$addagent = '
 INSERT INTO 
        '.$wpdb->prefix.'lcl_user_agent
        (user_agent, hitcount, click_timestap) 
    SELECT 
        visite_useragent, visite_hitcount, click_timestap 
    FROM 
        '.$wpdb->prefix.'lcl_visite_agent
    WHERE
        agent_id IN (' . $agent_id . ')
 ';
