ODI Loading Empty Strings from Flat File as Whitespace Instead of NULL (Doc ID 2759160.1)

Last updated on AUGUST 31, 2023

Applies to:

Oracle Data Integrator - Version and later
Oracle Data Integrator on Marketplace - Version and later
Information in this document applies to any platform.


After upgrading Oracle Data Integrator (ODI) to, flat files that contain a field which has a blank value such as an empty string, are resulting in whitespace being inserted into the target. Previously, the behavior was to insert a NULL value.

Additionally, If the mapping is attempting to insert data from a source file column specified as "String" into a "Numeric" column in an Oracle target, the issue can surface as an "ORA-01722: invalid number" error message.
