CON_ID_TO

Syntax

Description of the illustration con_id_to_guid.eps

Purpose

CON_ID_TO_GUID takes as an argument a container CON_ID and returns the container's GLOBAL UNIQUE ID ( GUID). For CON_ID you must specify a number or an expression that resolves to a number. The function returns a NUMBER value.

This function is useful in a multitentant container database (CDB).

Example

The following query displays the CON_ID, NAME and GUID for all containers in a CDB:

SELECT CON_ID, NAME, GUID FROM V$CONTAINERS;

CON_ID      NAME           GUID
–------     –-----------   –--------------
   1        CDB$ROOT       A8C0E03CB11A132FE0532684E80A96B3
   2        PDB$SEED       A8DA5D32F8F5590DE053C4E15A0A6EED
   3        CDB1_PDB1      A8DA63CEAD385A5BE053C4E15A0A774A
   4        SALESPDB       A8DA9AB18CE85BD0E053C4E15A0AE2C3

The following statement returns the container GUID given the container CON_ID 4:

SELECT CON_ID_TO_GUID(4) "CON_GUID" FROM DUAL;
    CON_GUID
