Morgan's Library Page Footer
The Library is currently in the process of being upgraded from Oracle Database Version 126.96.36.199 to
188.8.131.52. Demos are being upgraded to reflect the new Container paradigm as well as EBR (Edition Based Redefinition) and may contain
references to CDBs, PDBs, and other objects you may not be familiar with such as CDB_OBJECTS_AE: Welcome to 12c.
These functions are specific to obtaining character set related information. String functions are on a separate page linked at page bottom.
