In older Oracle, a Unique Index was created (*I think*) whenever a Primary Key was created. I think this is no longer true. My objective is to automate insert, update, and deletes in ~1000 oracle tables based on uniqueness, using dynamic SQL. <br />

Thanks,<br />

When a Oracle Unique Index is defined for a table, and no Primary Key or Unique Key is defined for the table (Or a Primary Key or Unique Key is defined that has less columns than the Unique Index) Is the unique index enforced for table updates and inserts for Oracle 11 and/or previous releases?

Oracle Unique Index without matching Primary Key or Unique Key

Oracle is an object-relational database management system. It supports a large number of languages and application development frameworks. Its primary languages are SQL, PL/SQL and Java, but it also includes support for C and C++. Oracle also has its own enterprise modules and application server software.
