Scalable Database Server, HiRDB Version 8 UAP Development Guide
During table manipulation, it is possible to add new indexes or to change the configuration of an index to change the processing or to improve retrieval efficiency. However, adding unnecessary indexes reduces retrieval efficiency.
If a UAP is running using a schema, you cannot add or delete an index for the table in the schema.
