Information in this document applies to any platform.
This article provides an example of a custom rule-based transformation for that renames a schema in the even of certain type of DDL statement and Declarative Rule Based Transformation for renaming the schema name
in the event of DML.Declarative transformations can transform row LCRs only. These row LCRs can be captured by a capture process, captured by a synchronous capture, or constructed and enqueued by an application. Therefore, a DML rule must be specified when you run this procedure. If a DDL is specified, then the procedure raises an error.
And actually, if you try to apply that rule-based transformation to DDL LCR rule, you get the following error:
ORA-26746: DDL rule "STRMADMIN"."SOURCE30" not allowed for this operation
So we need to create custome transformation function for DDL transformation.
