Unknown Column Left Join MySQL - mysql

Question

I've used the "NOT IN (select)" Function, but it takes too long to load on several registers. So I want to improve the query using LEFT JOIN, but I don't know what's wrong. I'm getting #1054 - Unknown column 'a.id_logistica' in 'on clause'.
The column "id_logistica" in table "logistica" does exists, as it does in "det_log" table. This is the code:
SELECT
a.*, a.id_logistica,
b.nombre username, c.placa,
b.nombre scliente, e.nombre ruta,
d.nombre_con, clase
FROM
logistica a, cliente b,
vehiculo c, conductores d, ruta e
LEFT OUTER JOIN
det_log t2 ON t2.id_logistica = a.id_logistica
WHERE
a.id_cliente = b.id_cliente AND a.id_ruta = e.id_ruta
AND t2.id_logistica IS NULL AND a.id_vehiculo = c.id_vehiculo
AND a.id_conductor = d.id_conductor AND activo = 1
and finalizado = 0 AND ( a.id_ruta > 1 OR a.borrado = 9 )
ORDER BY
fecha_des DESC

if your query was running, you can try this one :
SELECT
a.*, a.id_logistica,
b.nombre username, c.placa,
b.nombre scliente, e.nombre ruta,
d.nombre_con, clase
FROM logistica a
Left Join cliente b On b.id_cliente = a.id_cliente
Left Join vehiculo c On c.id_vehiculo = a.id_vehiculo
Left Join conductores d On d.id_conductor = a.id_conductor
Left Join ruta e On e.id_ruta = a.id_ruta
Left Join det_log t2 On t2.id_logistica = a.id_logistica
WHERE ( a.id_ruta > 1 OR a.borrado = 9 )
And activo = 1
And finalizado = 0
And t2.id_logistica IS NULL
ORDER BY fecha_des DESC
but, if i look the error. it's mean nothing column "id_logistica" in table "logistica".
please check column in table "logistica".
desc logistica;
maybe, you wrong to write.
