Ejemplo 7: Cláusulas LOB (con las palabras clave %{listValFile} y %{listValDir})

En el ejemplo siguiente se ilustra el uso de las palabras clave de plantilla %{listValFile} y %{listValDir}, especificadas con un rango de números en cláusulas LOBFILE y LOB IN. Las cláusulas LOBFILE y LOB IN se especifican de forma que se puedan generar los archivos LOB con los nombres siguientes:

La tabla EMP_PHOTO_IMP utilizada en este ejemplo tiene 64 filas.
