What we call the beginning is often the end
And to make an end is to make a beginning.
The end is where we start from. And every phrase
And sentence that is right (where every word is at home,
Taking its place to support the others,
The word neither diffident nor ostentatious,
An easy commerce of the old and the new,
The common word exact without vulgarity,
The formal word precise but not pedantic,
The complete consort dancing together)
Every phrase and every sentence is an end and a beginning,
Every poem an epitaph
– from Little Gidding by T.S. Eliot
A few years ago I wrote some SQL queries to assign dated records into groups defined by each record being within a fixed window of its starting record (the original Scribd document I wrote is embedded at the bottom). This is a bit harder than it sounds in pure SQL, without using PL/SQL, and I could only do it using new features from versions 10 and 11 of Oracle. With companies increasingly migrating to version 12, I thought it might be interesting to compare these queries with a query using the new 12c feature MATCH_RECOGNIZE. It turns out that the 12c query is both simpler and faster than the earlier queries. I’ll describe the problem with a simple functional test data set first, then will give the SQL for each of four methods with the execution plan for a larger data set. At the end I summarise the results from the four methods across a range of problem sizes.
I obtained these results on my Windows 10 home computer with Oracle 12.1, and used my own benchmarking framework that I wrote around the same time as the original queries, and have now published on GitHub, A Framework for Dimensional Benchmarking of SQL Query Performance.
See also Dimensional Benchmarking of General SQL Bursting Problems.
‘Bursting’ Problem Definition
The problem is to determine the break groups using distance from the group start point. In other words, once a group starts, all records that start within a fixed distance from the group start are in the group, and the first record after the end of a group defines the next group start. The data are partitioned by some key in general (here person_id). The problem data structure is based on a question posed in Tom Kyte’s Oracle forum, Activities and breaks, while the test data are my own.
ACTIVITY Table
CREATE TABLE activity (
activity_id NUMBER,
person_id NUMBER,
start_date DATE,
end_date DATE,
activity_name VARCHAR2(10)
)
/
CREATE INDEX activity_N1 ON activity (person_id, start_date, Nvl (end_date, '01-JAN-3000'))
/
CREATE INDEX activity_N2 ON activity (person_id, Nvl (end_date, '01-JAN-3000'), start_date)
/
Functional Test Data
I created test data with a test burst maximum length of 3 days, as follows, with groups shown at detailed level.

500w records are generated for each of three persons, where w is a 'width' parameter, with start dates randomized across a century, and a depth parameter is passed to the query for the number of days group limit via a system context.

Conclusions
- The new 12c feature MATCH_RECOGNIZE is a very powerful technique, and was much faster than the other techniques for this problem
- The results above showed that recursive subquery factoring had timings that increased quadratically with number of records; this was due to a product between the number of starts and full scans on a subquery
- This kind of unscaleable quadratic resource usage can often be avoided by the use of a temporary table with appropriate indexes, as demonstrated
- The depth parameter had little effect on timing, but I included it for the purpose of demonstration of the benchmarking framework
