Perhaps it works better for you in this case if you use the xquery language, instead of mil from your PHP script.

You might need to connect using xquery otherwise, but I'm not sure on that.

In PHP 4, OnUpdateInt is declared in Zend/zend_ini.h, in the same block which also declares OnUpdateString. Note that in your output there is no indication that OnUpdateString is not defined. zend_ini.h is include by php_ini.h which is included by php_monetdb.c. -- Sjoerd Mullender

[Monetdb-developers] license issues
by Sjoerd Mullender 13 Jun '05

13 Jun '05

There is a problem with the MonetDB and Pathfinder licenses. - The new (1.1) license is not yet available on the main web site; - On the staging web site (stem), the license is available with the wrong URL: .../Legal/MonetDBLicense-1.1/index.html instead of .../Legal/MonetDBLicense-1.1.html. I don't know whether the Development that is also stuck into the stem URL is a problem (that depends on how the URLs get translated when this moves to the real web site), but the ending is certainly a problem. The URL must end with MonetDBLicense-1.1.html and not MonetDBLicense-1.1/index.html. And the same for the Pathfinder license. -- Sjoerd Mullender

[Monetdb-developers] About MonetDB's modules
by Rodrigo Schmidt 01 Jun '05

01 Jun '05

Hello, I am PhD student at EPFL, Switzerland, and I am working on database replication. I just started looking at MonetDB and I have a simple doubt. Are modules like the SQL module written in MIL or in C/C++? I downloaded the sources of the SQL front end and I found some files whose extension is ".mx" and which seem to implement the SQL translator into MIL. The code looks pretty much like C++. Moreover, I read somewhere in your web page that two-phase-locking is implemented outside the database kernel. Where exactly is it implemented for the SQL front end? Thank you very much in advance! Best regards, Rodrigo Schmidt

[Monetdb-developers] DBD::monetdb: DBI registration
by Steffen Goeldner 01 Jun '05

01 Jun '05

I'd like to register DBD::monetdb as an official DBI driver: <http://search.cpan.org/~timb/DBI-1.48/lib/DBI/DBD.pm#Registering_a_new_driv…> Of course, the driver and prefix names should be stable. I think, after the last change from 'monet' to 'monetdb', this is the case. Any objections? Steffen

[Monetdb-developers] SQL upgrade instructions
by Sjoerd Mullender 27 May '05

27 May '05

I wrote the following text to help with upgrading the SQL database. I think something like this should be prominently displayed (or a prominently displayed pointer to the text) so that people read it *before* attempting to upgrade. Comments? Dumping the SQL database. ------------------------- Start the SQL Server and SQL Client as usual. In the SQL Client, type the following three commands. Type them without any extra white space: >.../dump.sql \D > That is, first a line consisting of a greater than symbol followed by the full (!) name of the file in which you want to store the dump. This will redirect future output to the file mentioned. Then a line consisting of just backslash-capital D. This command does the actual dump which is, because of the previous line, stored in the dump file. And finally a line with just a greater than symbol. This closes the file and redirects the output again to the screen. It is also possible to dump from the command line. Start a SQL Server, and then issue the command MapiClient -lsql -umonetdb -Pmonetdb --dump > dump.sql This command will connect to the SQL Server and dump the database into the file dump.sql in the current directory. Restoring the SQL database. --------------------------- After having dumped the database per the preceding instructions, it is possible to restore the database using the following commands. Start the SQL Server and SQL Client as usual. In the SQL Client, type the following command. <.../dump.sql That is, a less than symbol followed by the full (!) path name of the dump file that was produced using the dump instructions. It is also possible to restore from the command line. Start a SQL Server, and then issue the command MapiClient -lsql -umonetdb -Pmonetdb < dump.sql
