Comments in SQL
If a source DDL statement contains a comment in the middle of an object name, that comment will appear at the end of the object name in the target DDL statement. For example:
Source:
CREATE TABLE hr./*comment*/emp ...
Target:
CREATE TABLE hr.emp /*comment*/ ...
This does not affect the integrity of DDL synchronization. Comments in any other area of a DDL statement remain in place when replicated.
