Summary:

Added in Oracle Database 12c, SQL pattern matching (match_recognize) makes it easy to answer many questions that were hard-to-impossible with SQL.

But turning match_recognize clauses into reusable functions was tricky at best.

No more!

Added in 19.6, SQL macros enable you to define reusable code fragments. These return SQL that becomes part of your final SQL statement. Using macros, you can create reusable pattern matching clauses you can apply to any table.

This session is for developers and DBAs who want to get the best out SQL.
