[Monetdb-developers] ODBC driver

by Max Kad

Hi Guys, I've installed MonetDB yesterday on Ubuntu 11.10 and it seems working fine. I've 2 questions though: 1) I'm trying to install MonetDB ODBC driver for UnixODBC following the instructions at (http://www.monetdb.org/Documentation/Manuals/SQLreference/Programming/ODBC ) but for some reason I can't find the Monet ODBC libMonetODBC.so or libMonetODBCs.so driver. ( I found the following files: libmonetdb5.so.11, libmonetdb5.so.11.0.2 but I'm not sure what they are for. ) 2) Are there similar Date functions available on MonetDB as the following MySQL functions: UNIX_TIMESTAMP(), DATE() ) or an epoch function. I couldn't find it on the following link. ( http://www.monetdb.org/Documentation/SQLreference/Temporal ) Thanks in advance, Max

[Monetdb-developers] Announcement: New Apr2012-SP2 Bugfix release of MonetDB suite

by Sjoerd Mullender

The MonetDB team at CWI/MonetDB BV is pleased to announce the Apr2012-SP2 bugfix release of the MonetDB suite of programs. More information about MonetDB can be found on our website at <http://www.monetdb.org/>. For details on this release, please see the release notes at <http://www.monetdb.org/Downloads/ReleaseNotes>. As usual, the download location is <http://dev.monetdb.org/downloads/>. Apr 2012-SP2 bugfix release Client Package * Resolved a cosmetical error where tab-characters would cause misalignments in tabular result views. For the time being, tabs are now represented as a single space in tabular view. MonetDB Common * Limit number of detected CPU cores to 16 on 32-bits systems to avoid running quickly out of addressable resources followed by a kill from the OS. Bug Fixes * 2594: NULL cannot automatically be casted to every other type * 3085: assertion fails upon execution of a valid SQL query * 3086: Modulo function does not work in select from table * 3087: query causes "Not yet implemented" message * 3089: mserver5 crashed if join condition has two column and incorrect order * 3090: crashed if using single identifier for where condition * 3096: Type of median error
