FYI, I'm using the DBD::monetdb test suite to test the MonetDB ODBC Driver: set DBI_DSN=dbi:ODBC:driver=MonetDB ODBC Driver dmake test Here is the test summary: Failed Test Stat Wstat Total Fail Failed List of Failed --------------------------------------------------------- t\02cxn.t 5 1280 8 4 50.00% 7-8 t\12bind.t 1 256 6 1 16.67% 3 t\13count.t 16 4096 30 16 53.33% 12-27 t\23null.t 255 65280 14 22 157.14% 4-14 1 test and 2 subtests skipped. Failed 4/22 test scripts, 81.82% okay. 30/382 subtests failed, 92.15% okay. In light of all the additional layers, this is an unexpected good result. (Admittedly, my tests are not very aggressive.) And, even better, all is on the mend: t\02cxn.t This is a bug in DBD::ODBC: http://www.xray.mpe.mpg.de/mailing-lists/dbi/2005-02/msg00061.html fixed in svn: http://svn.perl.org/viewcvs/modules/dbd-odbc/trunk/dbdimp.c?rev=858&r1=561&r2=858 t\12bind.t This is bug #1229018: http://sourceforge.net/tracker/index.php?func=detail&aid=1229018&group_id=56967&atid=482468 t\13count.t This is a bug in DBD::ODBC. It looks like DBD::ODBC doesn't expect that an ODBC driver is able to return the number of rows of a result set. t\23null.t This is bug #1225455: http://sourceforge.net/tracker/index.php?func=detail&aid=1225455&group_id=56967&atid=482468 Steffen
