Syntax

Description of the illustration con_id_to_con_name.eps

Purpose

CON_ID_TO_CON_NAME takes as an argument a container CON_ID and returns the container NAME.

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). If you use this function in a non-CDB, then it returns 0.

Example

SELECT CON_ID, NAME FROM V$CONTAINERS;
    CON_ID         NAME 
   –--------       –------------
       1           CDB$ROOT
       2           PDB$SEED
       3           CDB1_PDB1
       4           SALESPDB   

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

SELECT CON_ID_TO_CON_NAME(4) "CON_NAME" FROM DUAL;
     CON_NAME
     –-------
