ESTIMATE.: 40 PROGRESS NOTES: DESCRIPTION: Add a DELETE operations that returns a result set of the deleted rows to the client. Suggested syntax: The DB2 syntax: DELETE from (SELECT column_list from single_table WHERE ... ORDER BY) another option would be DELETE FROM table_name WHERE ... [LIMIT #]] SELECT expression_list but I think that the first syntax is more clear. It's also easier to expand it to handle multiple tables. Oracle supports the following syntax: DELETE <table or expression> <alias> WHERE <where_clause> RETURNING <exprs> INTO <data_items> but this is not useful as it can only be used to record single row deletes.

[Maria-developers] Philip please test: Duplicate Elimination for outer joins + semi joins
by Sergey Petrunya 30 Jun '11

30 Jun '11

Hello Philip, I'd like to get the tree at lp:~maria-captains/maria/5.3-subqueries-mwl90 tested for Duplicate Elimination with outer+semi-join processing. I'm interested in crashes, as well as wrong query result bugs. The code path that needs to be tested is selected with this @@optimizer_switch setting: semijoin=on,materialization=off,firstmatch=off,loosescan=off this set of switches disables all semi-join subquery strategies except DuplicateElimination, so you should have no problem with hitting the If you also set "semijoin=off" then you get the execution path that we assume will always produce correct results. Query pattern SELECT .... FROM complex_join WHERE top_where AND (SELECT ... FROM complex_join WHERE ...) where - subqueries must be "mergeable semi-joins": = no aggregates, unions, or ORDER BYs - both correlated and ucorrelated subqueries are OK. - complex_join is arbitrary join structure (comma join, "t1 JOIN t2", various kinds of outer joins - everything should work) - multiple sibling subqueries, as well as nested subqueries are covered by what you're testing. EXPLAIN - Should have id=='1' && select_type='PRIMARY' on all lines. - Should use Start Temporary/End temporary.

Re: [Maria-developers] [Commits] Rev 2983: WL#77 - INSTALL PLUGIN * in http://bazaar.launchpad.net/~maria-captains/maria/5.2/
by Alexey Botchkov 29 Jun '11

29 Jun '11

I'm fine with this last patch. One thing i can think of is if we should add a new error instead of adding static english texts to the ER_CANT_OPEN_LIBRARY like 'API version for ... plugin ... not supported'. Second question if we should have INSTALL PLUGIN ... IF NOT INSTALLED; to be even more user-friendly.

[Maria-developers] MariaDB 5.3 docs
by Daniel Bartholomew 29 Jun '11

29 Jun '11

All, We're getting closer to the first beta release of MariaDB 5.3 and several of the new features have been documented in the Knowledgebase and linked to from this page: http://kb.askmonty.org/en/what-is-mariadb-53 What I don't know is if there are any features which have either: 1. not been documented in the Knowledgebase at all, -or- 2. been incompletely documented in the Knowledgebase but not added to the above page, -or- 3. been added to the page but incompletely documented. If you have worked on 5.3, please review the above page to make sure the items you worked on are present and fully documented. If they aren't please document them in the Knowledgebase and add them to the above page (or send me enough information about them so that I can document them). If they are present, but inadequately documented, please add what is missing or let me know what is missing. Don't worry about your documentation being perfect, I will clean it up. If you need any help, please contact me via email or on IRC. Thanks. -- Daniel Bartholomew MariaDB - http://mariadb.org Monty Program - http://montyprogram.com AskMonty Knowledgebase - http://kb.askmonty.org
