You are right, I have problem to revese index. I do have index in the database oracle 12c.
I have both indexes and constraints in the database oracle12c. The index name and coresponding constraint name are the same. I reverse engineered the model from the database, and found no index in the entitie list in the model generted. I modified one of the index name in the database, the index with the new name appeared in the entity list of model generated. It seems Toad modeler 5.5 assume there is no index when the name of index and the constraint is the same.
My headach is that I have an existing system with many indentical index name and corresponding contraint name. The indexes DO exist. How can I reverse engineer to generate model with the indexes?
