CON_ID

The ID of the container to which the data pertains. Possible values include:

•0: This value is used for rows containing data that pertain to the entire CDB. This value is also used for rows in non-CDBs.

•1: This value is used for rows containing data that pertain to only the root

•n: Where n is the applicable container ID for the rows containing data

所以CON_ID =1 是rootcontainer，
