DELETE en Multitablas asociadas

[NSD]

Código MySQL:

DELETE pedidos_general AS PG , pedidos_datos AS PD , pedidos_info AS PII 
WHERE PG.Fecha<'20120101' AND PG.ID=PD.ID AND PG.ID=PII.ID
 

ese codigo tambien me da error.

y usando una doble declaracion:

Código MySQL:

DELETE 
pedidos_general AS PG, pedidos_datos AS PD, pedidos_info AS PII 
FROM PG, PD, PII 
WHERE PG.Fecha < '20120101' 
AND PD.ID = PG.ID 
AND PII.ID = PG.ID
 

tengo nuevamente el mismo error

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'AS PG, pedidos_datos AS PD, pedidos_info AS PII FROM PG, PD, PII WHERE PG.Fe' at line 2

que molesto que una sentencia tan simple de tantos problemas...
