What about change all these tests to use mclient? It is a slave job, but it will make the things a lot easier because not every one has Java. So me and other users are not obliged to install Java package to check if all the tests are Green. It just a suggestion... Regards, Romulo

[Monetdb-developers] New MonetDB Release
by Stefan Manegold 28 Jun '08

28 Jun '08

Dear MonetDB users and developers, The MonetDB team at CWI is pleased to announce the new "Jun2008" release of the MonetDB suite of programs. For MonetDB/XQuery, this release marks the roll forward from the old "milprint_summer"-based Pathfinder compiler to the new "Algebra"-based Pathfinder compiler. MonetDB/SQL has been extended with initial support for OpenGIS via the "Geom[etry]" extension module, aka. MonetDB/SQL/GIS. Additionally, the configure defaults for compilation from sources on Unix(-like) systems as well as the Windows installers have been cleaned-up. For more information, please see the detailed release notes at http://monetdb.cwi.nl/Development/Releases/Version4.24/ IMPORTANT NOTE: Before upgrading to the latest "Jun2008" release from any previous release of MonetDB, please make a dump of your database, and rename/move/backup the database directories (dbfarm, sql_logs, xquery_logs). After the upgrade, restore your database, again. Once you have checked and confirmed the correctness of the restore, you can delete the above renamed/moved/backed-up old database directories. For more information, please see the detailed release notes at http://monetdb.cwi.nl/Development/Releases/Version4.24/ The new release consists of the following packages: MonetDB Common 1.24.0 MonetDB Clients 1.24.0 MonetDB4 Server 4.24.0 MonetDB4 XQuery 0.24.0 MonetDB5 Server 5.6.0 MonetDB5 SQL 2.24.0 MonetDB5 Geom 0.4.0 monetdb-1.8-jdbc.jar There is of course also a new "Super Source Ball", a tarball containing the combined sources. All this is available on our SourceForge project page. See https://sourceforge.net/project/showfiles.php?group_id=56967 for the downloadable files. Enjoy! The MonetDB development team. -- | Dr. Stefan Manegold | mailto:Stefan.Manegold@cwi.nl | | CWI, P.O.Box 94079 | http://www.cwi.nl/~manegold/ | | 1090 GB Amsterdam | Tel.: +31 (20) 592-4212 | | The Netherlands | Fax : +31 (20) 592-4312 |

[Monetdb-developers] Question about subquery to calculate median
by Rt Ibmer 20 Jun '08

20 Jun '08

Hello, I am trying to write a subquery that can serve as a poor man's median function. However I am running into issues every angle I try and cannot find any details about this in the docs or list archives. Question 1: Currently I can calculate the median manually as two steps: sql> select count(*)/2 from mytable where myIntVal is not null; +----------------+ | sql_div_count_ | +================+ | 10 | +----------------+ sql> select myIntVal as median from mytable order by myIntVal limit 1 offset 10; +--------+ | median | +========+ | 1172 | +--------+ However I cannot figure out how to combine these two queries into one query so that the count/2 can be done together with the query, so that I don't have to manually first get the count and then hard code it into the second query that does the median. How can these be combined? For instance I tried this which does not work: sql> select myIntVal as median from mytable order by myIntVal limit 1 offset (select count(*)/2 from mytable where myIntVal is not null); but this gives me: !syntax error, unexpected '(', expecting IDENT or sqlINT So I assume you can not dynamically substitute a subquery for an OFFSET value. But is there then another way to combine these statements into one statement? Question 2: Once I get the above resolved, I need to be able to get the median as an aggregate function, so that I can get medians in a group by query for each element in the group. For instance, if there really was a median() aggregate function I would do this: select median(myIntval), customerid from mytable group by customerid; However of course there is no median function. So I understand the work around for not having a median function is to get the total rows, sort the rows and then take the row in the middle. But how can I do that if it is in a group by statement like the above? What I am trying desperately to avoid is having to make a query to get all the group by results, and then for each result having to do a separate individual query to get its median separately. Please tell me this is possible! :) And if so, how? Thank you!!

[Monetdb-developers] database 'mydbname' does not allow connections error
by Rt Ibmer 18 Jun '08

18 Jun '08

Hello, I have a start up script as part of a server image that runs the first time a new instance of the server is started. It performs the following: # start the monetdb server /usr/bin/merovingian # create and start the db monetdb create mydb monetdb start mydb # create tables mclient -lsql --time --database=mydb < /db/schemas.sql However the mclient fails to execute the schemas. The consoles shows the following: successfully created database 'mydb' database 'bhtg' does not allow connections However, if I execute the same exact commands from a bash shell once the system is booted, then it works fine and the mclient executes the .sql script and creates the tables as expected. What could then be causing the error about not allowing connections? The startup script is running with this: # chkconfig: 345 15 95 So I think the network is fully initialized and operational by the time this runs. Any advice please? Thank you.

Yes. Thanks! One open questions: Was the change in pf_support that you committed with the same checkin on the development trunk (see below) related to the bug fix or not? If not, what was it for?

[Monetdb-developers] Pathfinder (MonetDB/XQuery) testing results
by Stefan Manegold 17 Jun '08

17 Jun '08

Dear all, after I finally switched the compile time default for Pathfinder from using the old MPS ("milprint_summer") back-end to using the new ALG ("Algebra") back-end last night, the nightly testing result for Pathfinder (aka. MonetDB/XQuery) are available at (`make check` using default ALG back-end): http://monetdb.cwi.nl/testing/projects/monetdb/Stable/pathfinder/.mTests103… http://monetdb.cwi.nl/testing/projects/monetdb/Current/pathfinder/.mTests10… (`RunMtest -g` explicitly using the old MPS back-end): http://monetdb.cwi.nl/testing/projects/monetdb/Stable/pathfinder/.mTestsg10… http://monetdb.cwi.nl/testing/projects/monetdb/Current/pathfinder/.mTestsg1… The TestWeb pages at http://monetdb.cwi.nl/Development/TestWeb/Stable/pathfinder/index.html and http://monetdb.cwi.nl/Development/TestWeb/Current/pathfinder/index.html will be updated accordingly as soon as we manage to re-buld the web-site ...

[Monetdb-developers] Question on monetdb PHP support
by Rt Ibmer 17 Jun '08

17 Jun '08

I am building Monetdb using the stable nightly builds. I would like to write queries against Monetdb using PHP. I came across this in the docs and have two questions about it: ---------------- The unix configure process normally tries to detect if you have PHP including developer packages installed and builds the PHP module only if you have it. With the --with-php option you could tell 'configure' where to find the PHP installation. ---------------- 1) Regarding "detect if you have PHP including developer packages" - can you please tell me what packages exactly MonetDB will look for. Obviously it wants the main php package. But I am not sure what development packages I need to install so that Monetdb will build in the PHP support and make me the DB/monetdb.php file. I am using Fedora 8. What yum packages (or equiv) should I have installed for this? 2) Regarding the "--with-php" compile option - which of the PHP base directories would I want to point the build .sh script for MonetDb at? Thanks!
