Function Based Index on SUBSTR Not Used When Cursor_Sharing=Force (Doc ID 2276684.1)

Last updated on JUNE 15, 2017

Applies to:

Oracle Database - Enterprise Edition - Version 12.1.0.2 and later
Information in this document applies to any platform.

Symptoms



Changes

Max_string_size=extended was added.


Old function based indexes cannot be created after upgrade to max_string_size=extended because of ORA-1450 <Document 136158.1>.  So indexes must be created on substring (substr(<fnc>,1,n)).
