This Note is intended to illustrate how you can rename columns in the LCR using a DML Apply Handler. The illustration is by example.
You may want to do this when you are capturing and applying between tables of different structures. In this case, the apply site has
table column names which are not present at the capture site table.  Alternatively, this can also be achieved by using a Transformation
Function at the capture or apply site.


To be used by DBA's as a reference when configuring and implementing the Oracle Streams apply process for table level replication.
