45e35f2745For SELECT queries that have GROUP BY ... WITH ROLLUP, reinitialise join->rollup when a GROUP BY vcol index substitution has happened. The (partial) reinitialisation reconstructs the rollup counterparts to all_fields/ref_pointer_array and fields_list since they may have changed during the substitution. It also sets up relevant fields of tmp_table_param after call to count_fields_types. We also add a new field vcol_back to ORDER that points to the original GROUP BY item on substitution, so that JOIN::make_rollup_fields masks the correct fields as NULL for super-aggregated rows. The partial reinitialisation does not repeat the setup of Item_refs in Item_funcs. This prevent breaking the reference which causes failure in the following case, where the a in a + 1 would no longer refers to the correct address after rollup reinit CREATE TABLE t (a INT,b INT,a1 INT GENERATED ALWAYS AS (a) VIRTUAL,INDEX (a1)) ENGINE=INNODB; insert into t (a, b) select seq / 10, seq from seq_1_to_100; SELECT a, a + 1, count(b) FROM t GROUP BY a WITH ROLLUP; drop table t; |

MariaDB: The innovative open source database
MariaDB was designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance.
MariaDB is brought to you by the MariaDB Foundation and the MariaDB Corporation. Please read the CREDITS file for details about the MariaDB Foundation, and who is developing MariaDB.
MariaDB is developed by many of the original developers of MySQL who now work for the MariaDB Corporation, the MariaDB Foundation and by many people in the community.
MySQL, which is the base of MariaDB, is a product and trademark of Oracle Corporation, Inc. For a list of developers and other contributors, see the Credits appendix. You can also run 'SHOW authors' to get a list of active contributors.
A description of the MariaDB project and a manual can be found at:
https://mariadb.com/kb/en/mariadb-vs-mysql-features/
https://mariadb.com/kb/en/mariadb-versus-mysql-compatibility/
https://mariadb.com/kb/en/new-and-old-releases/
Getting the code, building it and testing it
Refer to the following guide: https://mariadb.org/get-involved/getting-started-for-developers/get-code-build-test/ which outlines how to build the source code correctly and run the MariaDB testing framework, as well as which branch to target for your contributions.
Help
More help is available from the Maria Discuss mailing list https://lists.mariadb.org/postorius/lists/discuss.lists.mariadb.org/ and MariaDB's Zulip instance, https://mariadb.zulipchat.com/
