Rob,

I never said this had anything to do with the "catalog" per se ...


AFAIK, the SQL "catalogs" are not the official "repository" of the actual "definitions" on the IBM i platform -- (it could be quite a different story with Db2 LUW, Db2z, mariaDB, mySQL, Oracle, postGreSQL, SQL Server, SYBASE, etc.)


AFAIK, for IBM i and Db2i, that information resides inside the "objects" e.g. the *FILEs that house the "tables" or "views" or "indexes" etc. -- and the "catalog" is then subsequently updated to reflect that information and make it more easily accessible (via queries) and also to conform to the ANSI SQL standards.

Mark,
What I suspect here is that your DROP CONSTRAINT is being pointed to a specific table and can read the information from the table and not from the system catalog.
