CICS VSAM Transparency for z/OS, Version 1.2


Handling nullable columns in an IRD

The sample FBE CNULLCL shows you how CICS® VT supports nullable DB2® columns.

You can only use an FBE for a field that is mapped to CICS VT. MULTIRD shows that when you migrate a file to multiple DB2 tables, the IRD is responsible for building DB2 column values for the secondary tables. The secondary tables are not mapped to CICS VT, so your IRD is responsible for maintaining nullable secondary table columns.
