Tips and Techniques
Hierarchical queries in Oracle have always been a challenge, even for advanced SQL practitioners, with Oracle-specific SQL language elements which are not part of the SQL standards. Beyond the SQL-92 standard, the ANSI SQL:1999 standard added the definition of a recursive query which has now been adopted by Oracle. In this presentation, we'll talk about how to translate common CONNECT BY statements and use the new construct to solve more esoteric problems. The attendee will benefit by using this new standard, portable construct for hierarchical queries in Oracle and other databases.
