Can Siebel Tools Create Custom Index on one column with the Oracle SQL Syntax that Includes Null Values in Oracle RDBMS Index? (Doc ID 1993281.1)

Last updated on FEBRUARY 01, 2023

Applies to:

Siebel Tools - Version 8.2.2.4.2 [IP2013] and later
Information in this document applies to any platform.

Is it possible to use Siebel Tools to create an index like this so that the Oracle RDBMS index will include columns with null values?

Note: Starting in Oracle 11g, there is new "create index" syntax that allows NULL values to be included in the index:

create index
    emp_ename_idx
on
   emp
   (ename asc, 1)
;

Here, the "1" tells Oracle that to index on NULL values within the tables.
