How To Change VARCHAR (Byte) to VARCHAR (Char) for all tables in a Relational Model

(Doc ID 1948782.1)

Last updated on OCTOBER 27, 2016

Applies to:

Oracle SQL Developer Data Modeler - Version All and later
Information in this document applies to any platform.

Goal

There may be situations where modelers are required to work with tables in different database that have different NLS_LENGTH_SEMANTICS (Char vs. Byte).  This note suggests a possible way to convert the length semantics of an imported Relational Model to conform to the length semantics used by the target database.

It should be noted that this ony one possible approach, and that the design and code of Custom Transformation Scripts are the responsibility of customers and not Oracle Support.
