Documentation for OLAP extension
Introduction
------------
MySQL will first support CUBE and ROLLUP operators from entire OLAP
functionality.
The CUBE and ROLLUP extensions to SQL make querying and reporting
easier in data warehousing environments. ROLLUP creates subtotals at
increasing levels of aggregation, from the most detailed up to a grand
total. CUBE is an extension similar to ROLLUP, enabling a single
statement to calculate all possible combinations of subtotals.
Syntax:
------
The syntax supported by the enhanced mysql for CUBE and ROLLUP
operators.
CUBE
----
SELECT field1, field2, ... AGGR(fieldn) FROM
table GROUP BY field1, field2 field(n-1) WITH CUBE
This would generate the aggregates with group bys of all the
combinations of dimensions.
ROLLUP:
-----
SELECT field1, field2, ... AGGR(fieldn) FROM table
GROUP BY field1, field2 field(n-1) WITH ROLLUP
Example:
-------
mysql> select * from sales;
+------------+---------------+------+--------+

MySQL supports now CUBE and ROLLUP extensions, with all functions
that one wishes to use with them.
Those extensions already work in all tested combinations. They work
with UNION's, should work with sub-selects in 4.1 and derived tables.
TODO
----
For the moment, ORDER and LIMIT are disabled for CUBE and ROLLUP. This
however remains to be added later.
Another feature that has to be added later is grouping of select list
itmes in order to alleviate user errors. For the moment, missing
(hidden) columns are not used at all.
