What is the difference between Primary key and
unique index?

Answer Posted / guest1

Using the Primary Key you can establish referential
integrity. Unix index will be created upon the Primary Key
column, and the data will be seperately placed in the Index
space. If you have not created Unix Index, while accessing
the table it leads to SQLCODE = -540
