Im looking for information but I didnt find how.

I have two tables:

* Remesas

> 
> 
> ```
> |codigo_prod|  nombre   |codigo_proveedor|
> -----------------------------------------
> |    1001   | product1  |     EST        |
> |    1002   | product2  |     ASM        |
> 
> - Proveedores 
> 
> |codigo_proveedor|  mail         |
> ----------------------------------
> |    EST        | pro@mail.com  |
> |    ASM        | pro2@mail.com |  
> |    DAM        | pro3@mail.com |
> 
> ```
> 
> 

I have to delete from Proveedores the row that dont have codigo\_proveedor on Remesas
in this case delete DAM that its not on Remesas.

Thank you!
