Description copied from class: SQLStringVisitor

Take the specified derived group and element short names and determine a replacement element name to use instead. Most commonly, this is used to strip the group name if the group is a pseudo-group (DUAL) or the element is a pseudo-group (ROWNUM). It may also be used to strip special information out of the name in source value in some specialized cases. By default, this method returns null, indicating that the normal group and element name logic should be used (group + "." + element). Subclasses should override and implement this method if desired.

Overrides:

replaceElementName in class SQLStringVisitor

Parameters:

group - Group name, may be null

element - Element name, never null

Returns:

Replacement element name to be used as is (no modification will occur)
