This article describes why Oracle imposes restrictions on these and how to get around them, if possible.

Scope

Oracle7 and Oracle8 server releases imposed many restrictions on materialized views; some of these restrictions have been removed with Oracle 8i, 9i, and on up through 12c. This note applies to those that persist among all the versions.
