OLL Live webcast - Using SQL for Pattern Matching in Oracle Database

You've visited our new web page on OTN, you've downloaded the pattern matching iBook, now register for the webcast!

If you are interested in learning about our exciting new 12c SQL pattern matching feature then mark your diaries. On Wednesday, October 30th at 8:00 am (US/Pacific time zone) Supriya Ananth, who is one of our top curriculum developers at Oracle, will be hosting an OLL webcast on our new SQL pattern matching feature.

The ability to recognize patterns in a sequence of rows has been a capability that was widely desired, but not possible with SQL until now. Row pattern matching in native SQL improves application and development productivity and query efficiency for row-sequence analysis.

With Oracle Database 12c you can use the new MATCH_RECOGNIZE clause to perform pattern matching in SQL to do the following:

  • Logically partition and order the data using the PARTITION BY and ORDER BY clauses
  • Use regular expressions syntax to define patterns of rows to seek using the PATTERN clause. These patterns a powerful and expressive feature, applied to the pattern variables you define.
  • Specify the logical conditions required to map a row to a row pattern variable in the DEFINE clause.
  • Define measures, which are expressions usable in the MEASURES clause of the SQL query.
