[MonetDB-users] Insert tuples with special characters especially umlauts
by Sebastian Bräuer 09 Jun '09

09 Jun '09

Hallo everybody, I would like to know whether there exist any possibilities to add tuples with umlauts as characters (ä,ö,ü) or other special characters like ß to tables. I tried to use the regular INSERT-statement as well as the COPY INTO-statement with a csv input file but without success (unexpected end of input error or missing ' to close the string). Example: CREATE TABLE Umlautnamelist(CUST_ID numeric(9,0) not null, CUST_NAME varchar(100) not null, constraint Umlautnamelist_PK primary key (CUST_ID)); INSERT INTO Umlautnamelist (123456789,'Bräuer'); Are there any chances to get it working? Thank you in advance. Sebastian

[MonetDB-users] possible bug in monetdb-install.sh
by Ying Zhang 09 Jun '09

Hi, I was using moentdb-install.sh to install the May 2009 release with the following command, which ends in an error: ================================ $ monetdb-install.sh --prefix=[pathto]/mdb_may2009 --enable-optimize --enable-xquery --22:11:36-- http://www.ins.cwi.nl/~monet/tars/latest/release/MonetDB.tar.bz2 => `/private/var/tmp/MonetDB-1244491895/MonetDB/ MonetDB.tar.bz2' Resolving www.ins.cwi.nl... 192.16.196.21 Connecting to www.ins.cwi.nl|192.16.196.21|:80... connected.

[MonetDB-users] connecting to mserver
by Henrik Vendelbo 08 Jun '09

08 Jun '09

I've installed mserver in a fresh Ubuntu Jaunty running in vmware, but cannot seem to connect. At first I thought it was just because I hadn't opened port 50000 in iptables, but things are a bit odd even now that I have opened the port. within Ubuntu port 50000 only seems to be open on the lo interface, while on the eth0 interface it is closed. Can this be an issue with mserver or is it just my iptables conf that is screwed?

[MonetDB-users] CRT and GKLoad errors
by Florian Joßbächer 08 Jun '09

08 Jun '09

Hi, I am trying to run the Star Schema Benchmark with Scale Factor 10 on MonetDB and get the following errors while loading the tables from a csv. The GKLoad-Errors occur just once in a while, the CRT-error is reproducible. Every time I try to run SF10, the server crashes while loading the lineorder-table (SF10) - with SF1 everything works fine. I googled this issue but only found a hint deleting a registry-key which is not existing on my machine. What can I do? Best regards, Florian.

Re: [MonetDB-users] [Monetdb-developers] problems with starting the monetDB4xquery server
by Mtekel 07 Jun '09

07 Jun '09

Hello, I have carefully read the link you have sent me. Too bad comments are closed. I have now uninstalled my 20090424 version and installed the newest 20090530. However I still have problems running the server. The 2009 4 24 version wouldn't start even after loading all the modules by hand from the Mserver interactive commandline - nor the client or browser would connect. They would just hang, connecting forever. Now this works for the 05 30 version, but I can't use the web interface (which now works) for adding the files - I get a bug (I'm not sure If I am allowed to send attachements, so I'll include them in the next mail). Adding from commandline, mclient --language=xquery -I %1 -C WOcollection < %1 , where %1 is filename, works, but the collection name is %1 WOcollection (e.g. three different files end up in different collections instead of one). What is more interresting, if I try to run pf:add-doc("DATA_wo3.xml", "DATA_wo3.xml", "WOcollection", 1) from the client's interactive commandline, I get this error (no matter where the file really is): MAPI = monetdb@localhost:50000 QUERY = pf:add-doc("DATA_wo3.xml", "DATA_wo3.xml", "WOcollection", 1) ERROR = !ERROR: interpret: no matching MIL operator to 'ws_create(int)'. I have run procmon and created trace as described in the link, the file is attached (to the second mail). I hope this issue can be solved somehow, Best regards, Michael -----Original Message----- From: Ying Zhang [mailto:Y.Zhang@cwi.nl] Sent: 2. júna 2009 10:41 To: Mtekel Cc: monetdb-developers(a)lists.sourceforge.net Subject: Re: [Monetdb-developers] problems with starting the monetDB4xquery server Hello Michael, Thanks for using MonetDB, and sorry for the inconvenience!

[MonetDB-users] Announcement: New feature release of MonetDB suite
by Sjoerd Mullender 05 Jun '09

05 Jun '09

The MonetDB team at CWI/MonetDB BV are pleased to announce the new "May2009" feature release of the MonetDB suite of programs. This is a feature release, however it is is (mostly) backward compatible with the previous releases (Nov2008 and Feb2009). The two slight incompatibilities are: - The way string data is stored was changed for 64-bit architectures with 32-bit OIDs. There is however an automatic conversion on startup of the server. The biggest problem is, you can't go back to an older version once the new version has run. This incompatibility affects only the Windows 64 bit build (the other 64 bit builds use 64-bit OIDs). - The default location of the write-ahead log (WAL) has changed. This is relevant for both MonetDB5/SQL and MonetDB4/XQuery on all platforms. When the server first starts on an existing database, it will notice that the WAL is missing and will refuse to continue with a message which indicates where the WAL is now expected. You can either use a command line option to tell the server where the WAL is, or you can manually move the WAL to the new location. This latter option is done automatically on Windows when you use the Start menu to start the server. More information on the new release (and the above mentioned incompatibilities) is available at <http://monetdb.cwi.nl/projects/monetdb/Development/Releases/May2009/>. The sources and binaries are available at <http://monetdb.cwi.nl/projects/monetdb/Download/>. -- Sjoerd Mullender

[MonetDB-users] Best way to lookup a varchar field?
by Henri Asseily 04 Jun '09

04 Jun '09

Hi, I've got a very simple table structure in SQL, with a non-unique varchar field and a few other fields including a CLOB. I found that it's abnormally slow to filter the varchar field with an 'IN' statement and simply return the CLOB. i.e.: select clob from x where varchar in ('a','b','c') With a couple million rows, the query is in multiple seconds if the results are around a couple thousand rows. Is there something I'm doing wrong? I should be just the varchar BAT filter, then join on the CLOB BAT. Should I manually assign the varchars to integers in another table and use ints on this table? That would be surprising... Thanks. H
