Informix HPL message 23221: There is no mapping to column %s which cannot accept null values

Oninit® Troubleshooting Guidance

What it means

A column that cannot hold NULL has no field mapped to it in the record map, so a load would insert a NULL into it.

Common causes

• The map was built before the column was added or made NOT NULL.
• The column was left out of the map by mistake.

What to do

• Add a mapping (or a default value) for the column in the map, or change the table definition.
