Multiple XMLSchemas Support per XMLType column in Oracle 11gR1 (Doc ID 1550057.1)

Last updated on AUGUST 04, 2018

Applies to:

Oracle Database - Enterprise Edition - Version 11.1.0.7 to 11.1.0.7 [Release 11.1]
Information in this document applies to any platform.

Goal

Is it possible to allow multiple schemas per XMLTYPE column to prevent sparse table handling?

For example,  if there are 10 possible schemas that are contenders for a particular XMLTYPE, then per insertion you would waste 9 columns containing NULLs for the 1 column that will contain the actual XMLTYPE.
