CON_NAME_TO_ID
takes as its argument a container name and returns the container ID. For container_name
, specify a string, or an expression that resolves to a string, in any data type. The function returns a NUMBER
value.
This function is useful in a multitenant container database (CDB). If you use this function in a non-CDB, then it returns 0.
The following query displays the ID and name for all containers in a CDB. The sample output shown is for the purpose of this example.
SELECT CON_ID, NAME FROM V$CONTAINERS; CON_ID NAME ---------- ---------- 1 CDB$ROOT 2 PDB$SEED 4 SALESPDB
The following statement returns the ID for the container named SALESPDB
:
SELECT CON_NAME_TO_ID('SALESPDB') "Container ID" FROM DUAL; Container ID ------------ 4
